Trust1Connector API DNS

The Trust1Connector API v3 exposes a secure REST API on the client device. Trust1Team has created a t1c.t1t.io DNS entry (or customer-specific DNS entry) that points to 127.0.0.1 in order to facilitate SSL communication. This means that if the customer infrastructure uses a proxy for all network traffic, an exemption must be made for t1c.t1t.io to always point to the origin device's loopback address. The same holds true for the localhost domain name, this should redirect to 127.0.0.1 on the user's local system, not the localhost of the proxy server.

If no exemption is made and https://t1c.t1t.io is handled by a proxy, it will redirect to 127.0.0.1 IP of the proxy server instead of the local machine, and the Trust1Connector API will be unreachable.

The reserved domain from Trust1Team (t1c.t1t.io) has been registered with DNSSEC on the aforementioned URI. When a PARTNER uses its own DNS, we strongly recommend applying DNSSEC on the domain used in production.

DNS rebind protection

Some (corporate) networks have a policy that disables the ability to bind a domain to a local network IP. The Trust1Connector relies on this for t1c.t1t.io which resolves in to 127.0.0.1 which is a local ip for localhost

If DNS rebind protection is enabled it is unable to use t1c.t1t.io for connection towards the Trust1Connector because the network does not allow this Domain to be a local ip-address.

To resolve the issue either DNS rebind protection can be disabled or you can whitelist the domain t1c.t1t.io to allow this domain.

Applications using the Trust1Connector

Applications that want to make use of the Trust1Connector will be run from a specific domain. This means that the Trust1Connector needs to know that certain domains/applications want to make use of the Trust1Connector's functionality.

For these applications to gain access to the Trust1Connectors API we need to whitelist the domain in whats called the cors list. This list contains all the accepted domains that can make use of the Trust1Connector.

Distribution Service

In order to correctly function, the Trust1Connector API must be able to connect to its configured Distribution Service. You must allow REST traffic to the following URLs (if applicable):

• Acceptance: https://acc-ds.t1t.io

• Production: https://ds.t1t.io

A partner can opt for its own Distribution server, whereas the URIs mentioned above, will be defined by the hosting party.

The option of working without Distribution Service is also possible. You can find all the possibilities to run the Trust1Connector here

In some cases (environments) the Domain acc-ds.t1t.io or ds.t1t.io are not accessable. If this is because the domain cannot be resolved we do recommend to either ask the network/system administrator to make sure that those domains can be resolved on the network. Or changing the DNS server to the google DNS (8.8.8.8 & 8.8.4.4), this has solved the issue for some of our customers.

Disk Space

Windows

Trust1Connector installer is about 20Mb in size. The installed size comes to 40-50Mb.

This includes the Trust1Connector API, Registry and Sandbox.

MacOS

Trust1Connector installer is about 20Mb in size. The installed size comes to 40-50Mb.

This includes the Trust1Connector API, Registry and Sandbox.

The increased size over windows mainly comes to the way MacOS handles dialogs. These are distributed with the Trust1Connector as seperate binaries.

API Key

This API key must be requested from TRUST1TEAM, or created by the customer if they are hosting their own Distribution Service. The API key must never be used in a front-end application (where the API key can be compromised). The API key is needed to exchange the token, using a Distribution Server, resulting in a short-lived Json Web Token.

A PARTNER can decide to distribute a version without the use of a JWT. In those cases, the liability of the security flow resides completely in the context of the web application, thus Trust1Team can not guarantee the security context where the Trust1Connector is integrated upon.

Operating System

Trust1Connector support two operating systems for all tokens, Linux (Debian/Ubuntu) for PKCS11 tokens; On request, a Google Chromebook can be supported depending on the deployment or target installer.

• MacOS 11.x or higher

  • X86 architecture

  • M1/M2/ARM architecture

• Windows 810 or higher

Trust1Team support Windows/Mac OSX OS families where lifecycle support is guaranteed from the Vendor of the Operating System. The moment the OS version has been marked as ‘end of life’, Trust1Team can not guarantee the functionality anymore.

When PARTNERS are in need to support an older version or keeping the support running on the level of Trust1Team, no guarantees can be made. Trust1Team can setup a custom project, on demand of the PARTNER. Those requirements, changes or other adaptations needed, are not covered in the Trust1Connector license fee.

Windows 8.1 or higher

To run in user-space on Windows 8.1 or higher some components have to be set on the operating system

Registry keys

Below you can find a list of all registry keys that will be created for the working of the Trust1Connector, All these keys are added to HKCU

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

HKEY_CURRENT_USER\SOFTWARE\Trust1Team\Trust1Connector

Cookies

Since 3.5.x no more cookies are used.

Browsers

The Trust1Connector is browser agnostic so it does not matter what browser is being used as long as it support HTTP communication (HTTP 1.1) (which should all of them).

Version wise we do recommend to use the latest versions of your browser for security reasons but the versions below is was we accept as a minimum

• Chrome >80

• Firefox >75

• Edge 88 or higher

• IE 11 (End of Life is June 15 2022)

• All other browsers. As recent as possible

Introduction

The Trust1Connector core services address communication functionality with local devices. The Trust1Connector core exposes 2 main interfaces:

• interface for web/native applications using JavaScrip/Typescript

• REST API as a new approach and to incorporate the Trust1Connector as a microservice in the application architecture

In this guide, we target only the use of Trust1Connector's core interface for web/native applications. The T1C-SDK-JS exposes protected resources for administration and consumer usage.

Consumer resources

Consumer resources are typically used from an application perspective:

• Get pub-key certificate

• Get version

• Get Information (operating system, runtime, user context, variable configuration)

• List card-readers (with active card)

• Get card-reader

• List card-readers (with active cards)

• List card-readers (with or without active card)

• Trigger a push of the log files towards the DS

Executing these functionality is explained further.

Core Functionalities

The Trust1Connector functionalities are about secured communication with device hardware. The document highlights communication with smart card readers - contact and contact-less. Other hardware devices can be enabled or integrated as well in the solution. Some of the already are, for example printer drivers, signature tablet drivers, ...

List card readers

Returns a list of available card readers. Multiple readers can be connected. Each reader is identified by a unique reader_id.

T1CSdk.T1CClient.initialize(config).then(res => {
    var coreService = res.core();
    core.readers(callback);
}, err => {
    console.error(err);
});)

The response will contains a list of card readers:

{
  "success": true,
  "data": [
    {
      "id": "57a3e2e71c48cee9",
      "name": "Bit4id miniLector",
      "pinpad": false,
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": [
          "Belgium Electronic ID card (eID)"
        ],
        "module": "beid"
      }
    }
  ]
}

When multiple readers are attached to a device, the response will show all connected card readers:

{
  "data": [
    {
      "id": "ec3109c84ee9eeb5",
      "name": "Identiv uTrust 4701 F Dual Interface Reader(2)",
      "pinpad": false
    },
    {
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": [
          "Belgium Electronic ID card"
        ]
      },
      "id": "57a3e2e71c48cee9",
      "name": "Bit4id miniLector",
      "pinpad": false
    },
    {
      "id": "c8d31f8fed44d952",
      "name": "Identiv uTrust 4701 F Dual Interface Reader(1)",
      "pinpad": false
    }
  ],
  "success": true
}

Important to notice:

• The response adds a card-element when a card is inserted into the card reader.

• The response contains card-reader pin-pad capabilities

Card Inserted

As mentioned in the List card-readers, when a smart-card is inserted/detected, the reader will contain the cart-type based on the ATR. The ATR (Anwser To Reset), is the response from any smart-card when powered, and defines the card type. The Trust1Connector recognized more than 3k smart-card types.

{
  "data": [
    {
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": [
          "Belgium Electronic ID card"
        ]
      },
      "id": "57a3e2e71c48cee9",
      "name": "Bit4id miniLector",
      "pinpad": false
    }
  ],
  "success": true
}

Pin-Pad Capabilities

As mentioned in the List card-readers, when a card-reader has pin-pad capabilities, this will be mentioned in the response (notice the pinpadproperty):

{
  "data": [
    {
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": [
          "Belgium Electronic ID card"
        ]
      },
      "id": "57a3e2e71c48cee9",
      "name": "Bit4id miniLector",
      "pinpad": false
    }
  ],
  "success": true
}

List Card-Readers - Explained Example

The following example is the response for List card-readers on a device with 4 different card-readers attached:

{
  "data": [
    {
      "id": "ec3109c84ee9eeb5",
      "name": "Identiv uTrust 4701 F Dual Interface Reader(2)",
      "pinpad": false
    },
    {
      "card": {
        "atr": "3B67000000000000009000",
        "description": [
          "MisterCash & Proton card",
          "VISA Card (emitted by Bank Card Company - Belgium)"
        ]
      },
      "id": "e5863fcc71478871",
      "name": "Gemalto Ezio Shield Secure Channel",
      "pinpad": true
    },
    {
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": [
          "Belgium Electronic ID card"
        ]
      },
      "id": "57a3e2e71c48cee9",
      "name": "Bit4id miniLector",
      "pinpad": false
    },
    {
      "id": "c8d31f8fed44d952",
      "name": "Identiv uTrust 4701 F Dual Interface Reader(1)",
      "pinpad": false
    }
  ],
  "success": true
}

In the above example you notice that 4 card-readers are connected. Each card-reader receives his temporary id which can be used for other functions where a card-reader id is needed. This method can be requested in order to list all available card-readers, and optional cards-inserted. Each card-reader has a vendor provided name, which is retrieved from the card-reader itself. An additional property pinpad, a boolean value, denotes if the card-reader has pin-pad capabilities. A pin-pad is a card-reader, most of the times with its own display and key-pad. From a security perspective, it's considered best practice to use as much as possible pin-pad capabilities of a pin-pad card-reader. When a reader has a smart-card inserted (contact interface) or detected (contactless interface), the card type will be resolved by the GCL in order to respond with a meaningful type. In the above examples you see that; one card-reader has a Belgian eID card; another card-reader has a MisterCash or VISA Card available for interaction.

The readers returned, are the card-readers with a card available. The card-readers where no card is presented, are ignored.

Get card reader with card inserted

Returns a list of available card readers with a smart card inserted. Multiple readers can be connected with multiple smart cards inserted. Each reader is identified by a unique reader_id and contains information about a connected smart card. A smart card is of a certain type. The Trust1Connector detects the type of the smart card and returns this information in the JSON response.

T1CClient.initialize(config).then(client => {
    var coreService = client.core();
    core.readersCardAvailable(callback);
}, err => {
    console.error(err);
});

Response:

{
  "data": [
    {
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": []
      },
      "id": "57a3e2e71c48cee9",
      "name": "Bit4id miniLector",
      "pinpad": false
    }
  ],
  "success": true
}

Get the Javascript SDK version

To retrieve the version of the Javascript SDK you can use the version function available in the CoreService

You can follow the example below to retrieve the version number

T1CSdk.T1CClient.initialize(config).then(client => {
    var coreService = client.core();
    core.version().then(version => {
        console.log(version)
    });
}, err => {
    console.error(err);
});

The ouput in the log of the code above should look like the following

3.5.3

Get device public key

via the getDevicePublicKey endpoint you're able to fetch the public key information of the device. This requires an authenticated client to be able to access this endpoint.

This endpoint is used in the library to encrypt pin, puk and pace information so that it is not exposed in the network logs of the browser.

Encryption of pin, puk and pace is only possible when the Trust1Connector is registered via a DS and has a valid device key-pair. The SDK will automatically switch to send the pin, puk or pace info in clear text if its not able to encrypt. The Trust1Connector API will also detect if it has no valid device key-pair it will not try to decrypt the incoming pin, puk or pace information.

Push log files

Via the pushLogs function you can trigger the Trust1Connector to send out the log files towards the Distribution service.

Core interface

export interface AbstractCore {
  getImplicitConsent(codeWord: string, durationInDays?: number, callback?: (error?: T1CLibException, data?: T1CClient) => void): Promise<T1CClient>;
  validateConsent(consent: string, callback?: (error?: T1CLibException, data?: T1CClient) => void): Promise<T1CClient>;
  updateJWT(jwt: string, callback?: (error: T1CLibException, data?: T1CClient) => void): Promise<T1CClient>

  getUrl(): string;
  getDevicePublicKey(): void;
  dsCorsSync(): Promise<boolean>;
  pushLogs(): Promise<boolean>;
  version(): Promise<string>;
}

Introduction

The Trust1Connector API requires a valid JWT token to be provided in the Authorization header. This JWT token can be retrieved by asking the Distribution Service to generate a token for a specific API-key. It is important that this API-key is not exposed in the front-end application as this is a security violation.

When you've received a valid JWT token from the DS you can provide this into the configuration object when initialising the Trust1Connector JS client.

// Config object definition
export class T1CConfigOptions {
  constructor(
    public t1cApiUrl?: string,
    public t1cApiPort?: string,
    public t1cProxyUrl?: string,
    public t1cProxyPort?: string,
    public jwt?: string
  ) {}
}



// example
const configoptions = new T1CSdk.T1CConfigOptions(
  environment.t1cApiUrl,
  environment.t1cApiPort,
  environment.t1cProxyUrl,
  environment.t1cProxyPort,
  environment.jwt
);
config = new T1CSdk.T1CConfig(configoptions);

When using the Trust1Connector Javascript SDK the Authorization header is automatically populated with the JWT provided while initialising.

When the Token has expired there is a function which you can call to provide a new token and which will in turn return an updated client to be used.

Retrieving a JWT token

Retrieving a valid JWT token happens via the DS. When passing a valid API-key to header of the endpoint {{ds-url}}/v3/tokens/application (GET) you wil in turn receive a valid JWT token.

curl --location --request GET 'https://acc-ds.t1t.io/v3_5/tokens/application' \
--header 'apikey: your-api-key'

Example response

{
    "success": true,
    "data": "eyJraWQiOiJ0MWNkcyIsImFsZyI6IlJTMjU2In0.eyJpc3MiOiJ0MWNkcy1hcHAiLCJzdWIiOiJkZXZlbG9wbWVudCIsImV4cCI6MTU5OTA1MTExMywiaWF0IjoxNTk5MDQ5OTEzLCJuYmYiOjE1OTkwNDk5MDh9.LE_AdYv9PWxqSRm6-lkV_3TxInCqbf_hTwHFKCFfYwkuzex6AMkeW6FaVCOxu-EBU158S2g70i4VBpeT2TAr0IoOyjK-nalvVG5aB9MwidZMtiPlidcUfsDhsyhbhwqlhI2dzB5J5KsBmvZwpoG-Pg2koUSidruixg3SxRrCMotBRlRNKItnYgfs6_wvd_OOLXs2OlufYOD876MWcJymBK48wf9ESQ50clR3zwPAQsNnXFq2Augk0gOlCgWO1--WgaFeMnBF28b7genZXIkwZCfT82nRYtiOs0zLK2WtyireTHDgjIZif4nX8pggE7t_63Hbv8wCvv8_Mg2PfdhCMQ"
}

Refresh JWT token

A JWT token is only valid for a certain period. After this period the API will return an error. At this point you need to request a new JWT token to be able to communicate with the API.

In the T1C JS SDK there is a function which you can use to re-initalise the client with a new valid JWT token. This should be done when you receive a 104025 error-code which means you do not have a valid JWT

The updateJWT function can be found in the Core service. After initialising you can retrieve the core as follows:

const configoptions = new T1CSdk.T1CConfigOptions(
  environment.t1cApiUrl,
  environment.t1cApiPort,
  environment.t1cProxyUrl,
  environment.t1cProxyPort,
  environment.jwt
);
config = new T1CSdk.T1CConfig(configoptions);

T1CSdk.T1CClient.initialize(config).then(res => {
        client = res;
        console.log("Client config: ", client.localConfig)
        core = client.core();
    }, err => {});

The function's interface is as follows;

updateJWT(jwt: string, callback?: (error: T1CLibException, data?: T1CClient) => void): Promise<T1CClient>

This function returns an updated client which you can continue to use for your desired use-cases.

core.updateJWT("jwt").then(client => {}, error => {});

Distribution services

Downloading Trust1Connector

The T1C JS SDK no longer has a method to download the T1C installer.

Instead, the T1C installer can be downloaded by navigating the client browser to the /v3_5/downloads/installer endpoint of the Distribution Service (e.g. https://acc-ds.t1t.io/v3_5/downloads/installer). The Distribution Service will analyse the User-Agent header and automatically initiate the download of an OS-appropriate installer of the latest configured version. The user agent string parsing is considered "best-effort"; as they can vary wildly depending OS and browser software.

Alternatively, you can also initiate the download of a T1C installer with the following endpoints:

1. /v3_5/downloads/installers/{{OS}}: This endpoint allows you to specify the OS for which you wish to obtain an installer. The possible values are win32, win64, unix, macos macosarm.

2. /v3_5/downloads/installers/{{OS}}/versions/{{version}}: This endpoint allows you to download a specific version of a T1C installer for a specific OS.

Differentiate between MacOS architectures

For MacOS there are currently 2 supported architectures:

• ARM64 (M1, ...)

• Intel x86_64

Currently, browsers etc do not display which architecture you're running. So in order to provide download links to the users you need to provide them with the option to download any of the 2 architectures. The user needs to decide which platform he is running.

From the DS you can get both links with the following URL's (Production DS is used in the example);

# Intel x86_64
https://ds.t1t.io/v3_5/downloads/installers/macos

# ARM64
https://ds.t1t.io/v3_5/downloads/installers/macosarm

After this, you can provide the user with the choice of which one they want to download. Below you can see an example of how Google does this with their Browser, Google Chrome.

Here you can clearly see they provide two versions, with a recommendation on Intel because the majority of the users still run Intel Apple devices

Distribution services

Below you can find a list of Distribuction services available from Trust1Team. If you are integrating with a 3rd party that uses the Trust1Connector you can contact them for information regarding the Distribution services.

Example upgrade flow

Via the Distribution service you can fetch the latest available version. This can be done via the call

curl --location --request GET 'https://acc-ds.t1t.io/v3_5/versions/latest' \
--header 'Authorization: Bearer eyJh...BCr8Q'

This will return all information needed from the latest version, for example our latest version at this point returns:

{
	"success": true,
	"data": {
		"id": "3.6.0",
		"createdOn": "2022-03-21T07:47:48.590425Z",
		"updatedOn": "2022-05-30T10:46:36.532283Z",
		"recommended": false,
		"mandatory": false,
		"allowed": true,
		"visible": true,
		"uris": [
			{
				"os": "MACOSARM",
				"uri": "https://storage.googleapis.com/t1c-dependen....e/trust1team/Trust1Connector-arm.dmg"
			},
			{
				"os": "UNIX",
				"uri": "https://storage.googleapis.com/t1c-depend....trust1team/trust1connector.deb"
			},
			{
				"os": "MACOS",
				"uri": "https://storage.googleapis.com/t1c-dep....Trust1Connector Acceptance-x86.dmg"
			},
			{
				"os": "WIN64",
				"uri": "https://storage.googleapis.com/t1c-depe....t1Connector-Acceptance-x64.msi"
			},
			{
				"os": "WIN32",
				"uri": "https://storage.googleapis.com/t1c-dependenci...ust1Connector-Acceptance-x86.msi"
			}
		],
		"installationApiKey": "6257cbe3-e25a-.....-9fb9-02ad17d1f193"
	}
}

You can check the boolean values mandatory recommended and allowed to determine a pop-up for example, so that the user can download and use this Trust1Connector.

You can also retrieve the same information for a specific version. This endpoint returns the same response type as the latest version call:

curl --location --request GET 'https://acc-ds.t1t.io/v3_5/versions/3.6.0' \
--header 'Authorization: Bearer eyJh...BCr8Q'

Example screenshot below of our demo-application (rmc.t1t.io)

Below you can find an example of how an version check can be implemented in your front-end application.

🔺Mutex

The API and Registry use a feature called Mutexes to have data that can be shared over multiple OS threads. Using this is necessary for some functionality. In previous versions when you have a Shared environment (citrix for example) you could make the API and Registry get into what's called a DeadlockThis caused the Mutex to never be unlocked for use by another OS thread. Causing the connector to be blocked completely.This has now been solved and has been tested on instances of 1000 concurrent devices.

🔺System time out of sync

We had a user which Operating system had a custom date set (not synced) which caused issues with DS communication. The DS communication also checks wether the time of request is not in the future or in the past (with some slack ofcourse). So if you use the Connector with a custom date you will not be able to contact the DS because it requires a request within a correct time-zone.If this is not the case it could be that a malicious user is trying to exploit the DS at which point the DS refuses the request. The issue was that this caused the Connector to crash.This has been solved so that the Connector does not crash.System time must be correct, otherwise DS communication can not be done (secrity issue)

✅ Private Network Access

Private Network Access is a new CORS draft. Which prevents remote servers to contact local instances without any extra checks. Chrome has already implemented this draft in a non-blocking manner, the implemenation of chrome is to send 2 pre-flight requests. One which is the normal pre-flight and another one where the PNA implementation has been done.At this point the pre-flight for the PNA implementation is non-blocking meaning that if the pre-flight fails it will not block the request.When the PNA Cors draft is final this will become blocking.In this release we've already started adding some required components to support this in an upcoming release.

In this release we've implemented a feature where the Connector will send it's log files towards the DS. This is so that support desks can easily get the log files of the device which is requesting support.

We've added a feature where you can run the Connector in regualr HTTP mode. To still be secure we've added a signature field to the responses which can be verified to not be tampered with at the client's side. This verification is implemented in the JS SDK.

v3.6.3

v3.6.1

The consent error code has been updated in the Trust1Connector API library, and t1c-sdk-js clients have no impact on that change

When using different instances of the Trust1Connector (optionally from another partner) on a Windows system, a port collision could be possible due to a race condition in port assignment upon initialization. Ports are now protected with anti-collision and are salted to make a port less guessable.

When no LaunchAgents folder was present on the system, the installation procedure creates this folder implicitly.

Camerfima is a new PKCS11 token added to the modules of the Trust1Connector. The Camerfirma token pre-requisites the installation of the Carmerfirma middleware.

Chambersign is a new PKCS11 token added to the modules of the Trust1Connector. The Chambersign token pre-requisites the installation of the Chambersign middleware.

The token info endpoint has been implemented before only for identity tokens. We have added support for Token Info of the PKCS11 modules. As the response has a different data structure, an additional type has been added for clients to parse the response correctly.

The PKCS11 token info exposes information on the algorithms which can be used for different use cases (digital signature, validation, authentication, ...). In a future release additional functionality will be provided such as: encryption, decryption, key exchange,...

For the different notification types, many tokens share multiple certificates for a single type. The original interface supported only a single certificate response. To be backwards compatible, those certification function have been adapted to be behave the same as in v3.5.x.

New functions are available to support multiple certificate reponses, they are called: [certificateType]Extended. For PKCS11 tokens the certificate response also returns, besides the base64 encoded certificate and the certificate id, the following properties:

• issuer

• subject

• serial number

• hash sub pub key

• hash iss pub key

• exponent (payment modules)

• remainder (payment modules)

• parsed certificate (ASN1 format of the base64 encoded certificate)

A new function has been added for all PKCS11 modules called the 'validate' endpoint. This endpoint, when available, can be used to validate a signed hash received after calling the 'sign' function. In an next version a variant of the validation function using OpenSSL will be added for all tokens.

For the Trust1Connector to support more PKCS11 functionality, the intermediate PKCS11 layer has been removed in preference of a direct PKCS11 LIB integration. FFI is used in RUST to support any library which need to be loaded.

Additional guard has been implemented to prevent empty algorithms for the digital signature and validation endpoints. PKCS11 tokens will verify as well if the provided algortihm is exposed as an allowed mechanism for the targetted use case.

The Trust1Connector can now detec Java Card Object Platform 3 typed cards

When requesting for a signature or an authentication, the correct certificate must be provided. For PKCS11 tokens the certificate id (or reference) can be ommitted. The PKCS11 token will be default pick the first certificate (for the type needed) and use this with the specified mechanism to sign/authenticate.

Introduction

Mode of operations

The Trust1Connector's architecture is created so that we can support a wide range of system setups. This means we can both support single users using the Trust1Connector but also systems where multiple users make use of the same hardware, we call this shared environments.

Additionally to shared environments, we support remote desktops as an extension on shared environments.

Since Trust1Connector version 3.6.1 we can provide integrators the support to initialise the Trust1Connector in different ways.

Single Instance Without Consent

Using this operation mode, the integrator can decide to use the Trust1Connector and inforce that no consent is needed. making it very straightforward for the end-user to utilise any functionality the Trust1Connector offers.

In this mode we cannot support multiple instances of the Trust1Connector. Meaning shared environments and multiple users logged in on the same system can create unexpected behaviour.

Single Instance With Consent

Using Single Instance with consent as an operational mode, enforeces users to consent unregarded the environment - be it single device or multi user environment. Validity of the consent can be determined by the application.

Multi-user Instance With Consent

This mode support shared environments such as Citrix, terminal server and remote desktop.

Creating the configuration object

We will prepare the SDK's configuration Object, this object is used to pass information about which default port the Trust1Connector is running on, JWT key, API url, ... which is needed to properly contact and use the Trust1Connector.

Now we can create a complete Configuration Options object to be passed to the Trust1Connector.

T1CConfigOptions

The T1C config options is a class that can be used to create a valid configuration object to initialize the Trust1Connector. Below you can find a class definition.

class T1CConfigOptions {
  constructor(
    public t1cApiUrl?: string,
    public t1cApiPort?: string,
    public t1cProxyUrl?: string, // deprecated
    public t1cProxyPort?: string, // deprecated
    public jwt?: string,
    public applicationDomain?: string, // "rmc.t1t.be"
  ) {}
}

Parameters

t1cApiUrl: string Optional The URL that connects to the local Trust1Connector instances. This can be either localhost or a domain that directs towards localhost. By default this will be https://t1c.t1t.io

t1cApiPort: string Optional The port defined to be used for the Trust1Connector. By default this is 51983

t1cProxyUrl: string Optional - Deprecated The URL that connects to the local Trust1Connector Proxy instances. This can be either localhost or a domain that directs towards localhost. By default this will be https://t1c.t1t.io

t1cProxyPort: string Optional - Deprecated The port defined to be used for the Trust1Connector Proxy. By default this is 51983

jwt: string Optional The JWT token that is used to authenticate towards the Trust1Connector. This should be retrieved from the DS and is only needed when the Trust1Connector is configured to work with a DS and requires JWT validation

applicationDomain: string Optional The domain of the application that is using the Trust1Connector. This is used to make sure the consent is only available for a specific web-application. This prevents various clients to interfere with eachother. This domain also tags the Distribution service transactions being sent to the Distribution service. This makes it easy to distinguish between applications/tags for the transactions

// ...

let environment = {
    t1cApiUrl: 'https://t1c.t1t.io',
    t1cApiPort: '51983',
    t1cProxyUrl: 'https://t1c.t1t.io',
    t1cProxyPort: '51983',
    jwt: 'eyJraWQiOiJ0MWNkcyIsImFsZyI6IlJTMjU2In0..._Mg2PfdhCMQ',
    applicationDomain: 'test-app'
};

const configoptions = new T1CSdk.T1CConfigOptions(
        environment.t1cApiUrl,
        environment.t1cApiPort,
        environment.t1cProxyUrl,
        environment.t1cProxyPort,
        environment.jwt,
        environment.applicationDomain
    );
config = new T1CSdk.T1CConfig(configoptions);

// ...

When a remote DS is used you can set the following field with the correct DS url, this will in turn use the DS's capabilities of acting as a Trust1Connector proxy for enchanced security.

// When remote DS is used set the following parameter
config.dsUrl = "https://acc-ds.t1t.io";

Authenticated client

Initializing the Trust1Connector SDK

// ...

T1CSdk.T1CClient.initialize(config).then(res => {
    client = res;
    console.log("Client config: ", client.localConfig);
    core = client.core();
    core.version().then(versionResult => console.log("T1C running on core "+ versionResult));
}, err => {
    if (err.code == 814500 || err.code == 814501) {
        client = err.client;
        // (new) Consent is required
    }
    else if(err.code == 112999) {
        // Could not connect with the Trust1Connector
    } else {
        // an uncatched error occured
        console.error("T1C error:", err)
    }
});

// ...

When either no consent is present or its invalid you will receive a invalid client object (line 8 in example above) that can be used to trigger the getImplicitConsent function in the Core serivce.

The signature of the getImplicitConsent function is as follows;

public getImplicitConsent(codeWord: string, durationInDays?: number, 
    callback?: (error?: T1CLibException, data?: T1CClient) => void
): Promise<T1CClient>

This function expects:

codeword: string The string value that is saved to the user's clipboard needs to be sent to the Consent function.

durationInDays: number Optional Amount of days that the consent is valid.

callback: (error?: T1CLibException, data?: T1CClient) Optional Callback when you're not using ES

Below is a small javascript example of how you can trigger the getImplicitConsent function

client.core().getImplicitConsent(document.querySelector(".clipboard-data").innerHTML).then(res => {
    console.log("Consent Executed")
    client = res;        
    // Use the client for your use-cases
}, err => {
    // Failed, use the error client to retry the consent
    this.client = err.client;
    console.error(err.description ? err.description : err)
})

After this you will have a client that can be used to execute the rest of the functionality that the Trust1Connector has to offer.

Full example

// Global client to be used over the entire application
const client = null

// Prepare the configuration
let environment = {
    t1cApiUrl: 'https://t1c.t1t.io',
    t1cApiPort: '51983',
    t1cProxyUrl: 'https://t1c.t1t.io',
    t1cProxyPort: '51983',
    jwt: 'eyJraWQiOiJ0MWNkcyIsImFsZyI6IlJTMjU2In0..._Mg2PfdhCMQ',
    applicationDomain: 'test-app'
};

const configoptions = new T1CSdk.T1CConfigOptions(
        environment.t1cApiUrl,
        environment.t1cApiPort,
        environment.t1cProxyUrl,
        environment.t1cProxyPort,
        environment.jwt,
        environment.applicationDomain
    );
config = new T1CSdk.T1CConfig(configoptions);

// Initialize the Trust1Connector with the previously created configuration object
T1CSdk.T1CClient.initialize(config).then(res => {
    client = res;
    console.log("Client config: ", client.localConfig);
    core = client.core();
    core.version().then(versionResult => console.log("T1C running on core "+ versionResult));
}, err => {
    if (err.code == 814500 || err.code == 814501) {
        // (new) Consent is required
    }
    else if(err.code == 112999) {
        // Could not connect with the Trust1Connector
    } else {
        // an uncatched error occured
        console.error("T1C error:", err)
    }
});
    
    

// when the user has clicked on the clipboard/consent button we execute the getImplicitConsent function
document.querySelector(".clipboard").addEventListener("click", (ev) => {
    if (client != null) {
        client.core().getImplicitConsent(document.querySelector(".clipboard-data").innerHTML).then(res => {
            console.log("Consent Executed")
            client = res;        
            // Use the client for your use-cases
        }, err => {
            this.client = err.client;
            console.error(err.description ? err.description : err)
        })
    }

})

Enforcing consent flow in a optional consent enabled Trust1Connector

When your instance of the Trust1Connector has the optional consent mode enabled but still want to enforce the consent flow you can use the following explicit consent initialisation.

This will ignore the enabled feature of having the consent being optional and will require a valid consent to operate the Trust1Connector.

// ...

T1CSdk.T1CClient.initializeExplicitConsent(config).then(res => {
    client = res;
    console.log("Client config: ", client.localConfig);
    core = client.core();
    core.version().then(versionResult => console.log("T1C running on core "+ versionResult));
}, err => {
    if (err.code == 814500 || err.code == 814501) {
        client = err.client;
        // (new) Consent is required
    }
    else if(err.code == 112999) {
        // Could not connect with the Trust1Connector
    } else {
        // an uncatched error occured
        console.error("T1C error:", err)
    }
});

// ...

Clipboard

To provide a consent, we suggest you use the clipboard functionality available in browsers. The most supported way is via document.exeCommand and below you can find an example of this.

const tokenNode = document.querySelector('.consent-token');
var range = document.createRange();
range.selectNode(tokenNode);
window.getSelection().addRange(range);
try {
    // Now that we've selected the anchor text, execute the copy command
    document.execCommand('copy');
} catch(err) {
    console.log('Oops, unable to copy');
}

// Remove the selections - NOTE: Should use
// removeRange(range) when it is supported
window.getSelection().removeRange(range);
const clipboardData = tokenNode.textContent;

Retrieve JWT token

GET https://ds.t1t.io/v3_5/tokens/application

This endpoint will return a valid JWT token to use for a certain period based on the API-key you provide in the `apikey` header

Trust1Connector environments

The Trust1Connector has a Develop, Acceptance and production version. The difference between them is mainly the Distirbution service connection and the port number they use.

The port numbers of the Trust1Connector are;

Introduction

Initialize your module

When the user has selected his desired reader to use we can continue to initialize the module to use. This requires at least the readerID to properly initialize.

Some modules like the LuxID module require you to also add a additional pin and pinType for example, this will also need to be provided in the module initialization.

To initialize a module we first need the client as described in the introduction, here's a quick happy flow of how to retrieve a T1CClient

T1CSdk.T1CClient.initialize(config).then(res => {
    client = res;
}, err => {
    console.error(error)
});

When we have the T1CClient we can use this to choose our module. We can also use the generic interface if we want.

Base module initialization

Below is an example of how to iniailize the Belgian EID module. This is a specific module that has all the functionalities for the Belgian EID card. You can see we use the client to fetch an instance of the beid module which we can further use to execute any functionality exposed on the beid module.

const beid = client.beid(reader_id);

now we can use this to for example fetch all the available token data;

beid.allData(filters).then(...).catch(...)

Generic

Generic Token

Ofcourse we can also use the generic interface which has all the functions exposed that you can use for all the modules.

This will require you to always provide the module when you call any of its functions. Because it still needs to know which commands it needs to send to the card/token.

// pin and pin_type are needed for luxid
const generic = client.generic(reader_id, pin, pin_type)

When we now want to execute a getAllData for beid we would call it like this;

generic.allData('beid', filters).then(...).catch(...)

Generic Payment

To initialise a generic payment module its very similar to the token version but the available functions will differ.

const generic = client.paymentGeneric(reader_id)

When we now want to execute a readData for emv we would call it like this;

generic.readData('emv').then(...).catch(...)

Interfaces

Below you can find an overview of the generic interfaces. This shows what functions are available on both. If you want more information about a specific token/module you need to go to their respecitve pages which will explain more in detail what you can do with them.

You can find the trust1connector JS SDK for the Trust1Connector v3 via NPM

A Word of Introduction

The Trust1Connector Javascript SDK is a library that purely functions as a proxy towards the Trust1Connector API. This Library does not contain any business logic.

Include Trust1Connector JS SDK

From now on we will refer to the Trust1Connector JS SDK to the following variances;

• T1C-js/t1cjs

• T1C SDK

Using Trust1Connector in as a library

The Trust1Connector is a Javascript Library with TypeScript typings. This can be easily used in any web-application by loading the javacript files on the web-page.

Loading the T1C SDK onto a web-page can be done as shown in the code example below of a html page

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <script defer src="./T1CSdk.js"></script>
</head>
<body>
    ...
</body>
</html>

In the example you can see that we load the Javascript SDK on line 8

<script defer src="./T1CSdk.js"></script>

The defer attribute means that the script will be downloaded in parallel with the rest of the web-page but will be executed when the page has finished loading in.

This is mostly used to make sure that when the Javascript wants to target a specific element on the page, for example a div, that this element has already been loaded and is accessable.

Using Trust1Connector as a module

We also provide an npm package that makes it easier to load and use the Trust1Connector Javascript SDK as a module.

Architecture Overview

The following schematic seems rather complicated as it explains the inner workings of the Trust1Connector components, the concept is elaborate further on this page. If you are only interested in what the integration impact is for your Web Application in a Shared Environment, you can skip directly to the section: Integration in Web Applications

Components

Web Environment

The Web Application can use the T1C-SDK-JS or a custom REST API client for integration purpose. As the Web Application operates in a browser context, resolving an agent, by means of a consent, will result in a browser cookie being provided.

The T1C-SDK-JS implements the detection of a Shared Environment during the initialisation of the library. When initialisation succeeds without a controlled exception, the setup is a standalone; when the initialisation throws an 401 Error, the T1C-SDK-JS can be used to request the user for a Consent.

When using the REST API directly form your web application, reading the browser cookie and performing the initialisation must be done by the integrating Web Application itself.

Shared Environment Host

Compared to Trust1Connector v2, the v3 release has a separate component to be be installed on a shared host. This component is called the T1C-Proxy and only exposes the following use cases:

• Verify random available ports [in a predefined range] which can be used by an Agent (Session of T1C-API running in user space)

• Port reservation upon installation of a new T1C-API in an active user session

• Port registration upon initialisation of a T1C-API in an active user session

• Management of an in-memory list of active Agents

• Management of user consents in a shared environment by means of browser cookies with an optional configurable TTL (time to live)

The T1C-Proxy operates by Default on the API port defined in the T1C-DS (Distribution Server). From a Web Application perspective, this is the only information known. When a Web Application requests the information of the device, the PROXY device type will inform the Web Application that the targeted underlying API is a PROXY, which means that the Web Application must ask for the Agent specific API port to configure an URI which can be used to execute the use cases.

When using the T1C-SDK-JS this is done implicitly during initialisation.

Shared Environment Client

A T1C-API installed for a specific users runs in [User Space]. To avoid possible attack vectors, the Trust1Connector v3 will always run in [User Space].

Upon installation of the T1C-API, during the post install phase, the T1C-API will try to verify automatically if it is running in a shared environment. If this is the case, the T1C-API will ask the T1C-Proxy for available ports and will reserve those post, prior to initialisation and startup.

The ports which are reserved by the T1C-Proxy are the following:

• T1C-API Port: This is the port exposing the OpenAPI interface towards Web Applications and used by the T1C-SDK-JS

The T1C-gRPC instance is inherently a component from the T1C-API, and thus is managed by the T1C-API. As each user must have it's own hardened runtime for communication purpose, the port assigned for T1C-gRPC will be registered and configured by the T1C-API (and restarted when needed).

Central Back-Office

Starting from this release (v3) of the Trust1Connector, each device must have a link with an active and running T1C-DS (Trust1Connector Distribution Server). This is to guarantee security, updates, and avoid potential risk in production.

The T1C-DS is proceeded by an API Gateway who is managing the security offloading in the application layer. For a Web Application to communicate with a T1C-Proxy or T1C-API, a JWT (Json Web Token) is needed and obliged. The T1C-DS is responsible for the key management, the certificate management and other use cases which are described in a separate wiki.

In order to retrieve a valid JWT, the T1C-DS can be requested from your application back-end with a valid api-key. The JWT is valid for a given amount of time, and sets the context used when requesting the T1C-API on a device.

Pin Handling

The PIN handling logic is implemented in the Trust1Connector API. More information on the basic and/or advanced rules can be found on the following link:

Communication Stack

Introduction

The Belgian eID container facilitates communication with card readers with inserted Belgian eID smart card. The T1C-JS client library provides function to communicate with the smart card and facilitates integration into a web or native application. This document describes the functionality provided by the Belgian eID container on the T1C

Interface

Models

Get Belgian eID container object

Initialise a Trust1Connector client:

Get the Belgian eID container service:

Call a function for the Belgian eID container:

Obtain the Reader-ID

The constructor for the Belgian eID expect as the parameter to be a valid reader-ID. A reader-ID can be obtained from the exposed core functionality, for more information see Core services responds with available card-readers, available card in a card-reader, etc. For example: In order to get all connected card-readers, with available cards:

This function call returns:

We notice that a card object is available in the response in the context of a detected reader. The reader in the example above is Bit4id miniLector, has no pin-pad capabilities, and there is a card detected with given ATR and description "Belgian eID Card". An ATR (Answer To Reset) identifies the type of a smart-card. The reader, has a unique ID, reader_id; this reader_id must be used in order to request functionalities for the Belgian eID card. This must be done upon instantiation of the Belgian eID container:

All methods for beid will use the selected reader - identified by the reader_id.

Cardholder Information

The card holder is the person identified using the Belgian eID card. It's important to note that all data must be validated in your backend. Data validation can be done using the appropriate certificate (public key).

Sign Data

Algorithm

As the Beid module incorperates Beid 1.7 and 1.8 there is a difference in the algorithms being used. In 1.7 we have the following;

• md5

• sha1

• sha256

• sha512

For beid 1.8 we have;

• sha2_256

• sha2_384

• sha2_512

• sha3_256

• sha3_384

• sha3_512

As we've noticed most integrators use sha256 and to make sure current integrations do not break we have made the Trust1Connector to map sha256 to sha3_256 for beid 1.8. Ofcourse if you want to use a specifc supported algorithm you can still select them.

By default the 1.7 will fall back to sha256 and 1.8 to sha3_256 if an incompatible algorithm is passed to the function.

The tables below explain which algorithm will be used when providing a certain algorithm value in the function;

Belgian EID 1.7

Belgian EID 1.8

Signing

Data can be signed using the Belgian eID smart card. To do so, the T1C facilitates in:

• Retrieving the certificate chain (citizen-certificate, root-certificate and non-repudiation certificate)

• Perform a sign operation (private key stays on the smart card)

• Return the signed hash

To get the certificates necessary for signature validation in your back-end:

Response:

Depending on the connected smart card reader. A sign can be executed in 2 modes:

• Using a connected card reader with 'pin-pad' capabilities (keypad and display available)

• Using a connected card reader without 'pin-pad' capabilities (no keypad nor display available)

Security consideration: In order to sign a hash, security considerations prefer using a 'pin-pad'.

Signing with a Crelan card reader

When signing with a crelan card reader, it is additionally possible to optionally specify a transaction ID and the language. If the card reader is not a Crelan reader, these values will be ignored. This applies to all signing methods described below.

Sign Hash without pin-pad

When the web or native application is responsible for showing the password input, the following request is used to sign a given hash:

Response is a base64 encoded signed hash:

Sign Hash with pin-pad

When the pin entry is done on the pin-pad, the following request is used to sign a given hash:

Response is a base64 encoded signed hash:

The core services lists connected readers, and if they have pin-pad capability. You can find more information in the Core Service documentation on how to verify card reader capabilities.

Raw data signing

With the function signRaw you can sign unhashed document data. This means that the Trust1Connector will hash the value itself depending on the provided sign algorithm.

Below you can find an example

The function looks the same as a regular sign operation but expects a base64 data object that is unhashed.

Supported hash functions (SHA2) are;

• SHA256

• SHA384

• SHA512

Bulk Signing

Bulk PIN Reset

The PIN set for bulk signing can be reset by calling this method.

Response will look like:

Calculate Hash

In order to calculate a hash from the data to sign, you need to know the algorithm you will use in order to sign.

Hexadecimal result:

Base64-encoded result:

Now we can sign the data:

Result:

Note: If you want to convert a binary signed hash to HEX (for development) you can use for example an online hexdump tool:

Verify PIN

Verify PIN without pin-pad

When the web or native application is responsible for showing the password input, the following request is used to verify a card holder PIN:

Response:

Verify PIN with pin-pad

When the pin entry is done on the pin-pad, the following request is used to verify a given PIN:

Response:

Verify PIN - retries left

In order to inform a user upon the PIN retries left, the Belgian eID doesn't provide a request to retrieve this information. After an unsuccessful PIN verification, the error code indicates the number of retries left. For example, when executing:

Note that, when the user has at least one retry left, entering a correct PIN resets the PIN retry status.

Authentication

Algorithm

As the Beid module incorperates Beid 1.7 and 1.8 there is a difference in the algorithms being used. In 1.7 we have the following;

• md5

• sha1

• sha256

• sha512

For beid 1.8 we have;

• sha2_256

• sha2_384

• sha2_512

• sha3_256

• sha3_384

• sha3_512

As we've noticed most integrators use sha256 and to make sure current integrations do not break we have made the Trust1Connector to map sha256 to sha3_256 for beid 1.8. Ofcourse if you want to use a specifc supported algorithm you can still select them.

By default the 1.7 will fall back to sha256 and 1.8 to sha3_256 if an incompatible algorithm is passed to the function.

The tables below explain which algorithm will be used when providing a certain algorithm value in the function;

Belgian EID 1.7

Belgian EID 1.8

The T1C is able to authenticate a card holder based on a challenge. The challenge can be:

• provided by an external service

• provided by the smart card An authentication can be interpreted as a signature use case, the challenge is signed data, that can be validated in a back-end process.

  External Challenge

  An external challenge is provided in the data property of the following example:

  Response:

  Take notice that the PIN property can be omitted when using a smart card reader with pin-pad capabilities. The 'algorithm_reference' property can contain the following values: sha1, sha256, sha512, md5.

  Generated Challenge

  A server generated challenge can be provided to the JavaScript library. In order to do so, an additional contract must be provided with the 'OCV API' (Open Certificate Validation API).

Introduction

The Trust1Connector after correct initialization has the ability to retrieve the available card readers detected on the system. With these card readers you can continue and execute functionality such as retrieving biometric information, signing data, authentication, ...

List card readers

Returns a list of available card readers. Multiple readers can be connected. Each reader is identified by a unique reader_id.

The response will contains a list of card readers:

When multiple readers are attached to a device, the response will show all connected card readers:

Important to notice:

• The response adds a card-element when a card is inserted into the card reader.

• The response contains card-reader pin-pad capabilities

Card Inserted

As mentioned in the List card-readers, when a smart-card is inserted/detected, the reader will contain the cart-type based on the ATR. The ATR (Anwser To Reset), is the response from any smart-card when powered, and defines the card type. The Trust1Connector recognized more than 3k smart-card types.

In the response below you notice that this specific card also includes a module and description property. Both of these are arrays and are also optional. This means that the Trust1Connector recognizes this specific token and knows which module can be used for this token. The Trust1Connector has the possibility to detect that a card can be used by more than 1 module, in that case the module array will display multiple values depicting which modules can be used. The description is purely metadata.

Pin-Pad Capabilities

As mentioned, when a card-reader has pin-pad capabilities, this will be mentioned in the response (notice the pinpadproperty):

List Card-Readers - Explained Example

The following example is the response for List card-readers on a device with 4 different card-readers attached:

In the above example you notice that 4 card-readers are connected. Each card-reader receives his temporary id which can be used for other functions where a card-reader id is needed. This method can be requested in order to list all available card-readers, and optional cards-inserted. Each card-reader has a vendor provided name, which is retrieved from the card-reader itself. An additional property pinpad, a boolean value, denotes if the card-reader has pin-pad capabilities. A pin-pad is a card-reader, most of the times with its own display and key-pad. From a security perspective, it's considered best practice to use as much as possible pin-pad capabilities of a pin-pad card-reader.

When a reader has a smart-card inserted (contact interface) or detected (contactless interface), the card type will be resolved by the Trust1Connector in order to respond with a meaningful type. In the above examples you see that; one card-reader has a Belgian eID card; another card-reader has a MisterCash or VISA Card available for interaction.

Get card readers with card inserted

Returns a list of available card readers with a smart card inserted. Multiple readers can be connected with multiple smart cards inserted. Each reader is identified by a unique reader_id and contains information about a connected smart card. A smart card is of a certain type. The Trust1Connector detects the type of the smart card and returns this information in the JSON response.

Response:

Introduction

When you already have a V2 integrated this page will provide you with some easy steps to quickly migrate to the V3 of the Trust1Connector. Migration from the v2 to the v3 of the Trust1Connector can be done in 2 ways;

1. Integration of the API

2. Integration via the deprecated Javascript SDK

Both are viable integrations. When integrating via the API you have more control over the functionality and the dependencies used.

Update a v2 application to v3

For updating your web application first of all you need to use the new Javascript SDK. After this there are some differences in using the SDK from the v2.

Configuration

The configuration from the v2 has changed, we simplified this.

The v2 had the following configuration options;

With the v3 this is significantly simplified to the following;

Initialisation

After you've created your configuration object you can do the initialisation of the Trust1Connector SDK. This has largely remained the same except for the error codes.

V2 example:

V3 example;
