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.

Security

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:

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.

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 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.

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

Disk Space

Windows

Trust1Connector installer is about 15-20Mb in size. The installed size comes to 35-45Mb.

This includes the Trust1Connector API, Registry and Sandbox.

MacOS

Trust1Connector installer is about 15-20Mb 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

Right now Trust1Connector support two operating systems;

• MacOS 10.13 or higher

  • X86 architecture

  • M1/ARM architecture

• Windows 8.1 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

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.

Introduction

The Trust1Connector requires a user consent to function. This consent will be stored in the browsers localstorage for that user.

The consent token is stored with a domain specific key;t1c-consent-{{applicationDomain}}::{{apiUrl}}

When executing the consent flow, the user will be provided with a consent token which can be pasted into his clipboard. This token has to be passed with the Consent function which will perform a verfication (the token pasted in the clipboard - form the application context - should match with the token available on the clipboard for the T1C).

The consent can be configured to have an expiration date, when this expiration date has been exceeded, a new consent will be asked towards the user.

Consent dialog for implicit consent

Upon installation of the Trust1Connector, a user will not be able to retrieve any data from the connector without first giving its consent, agreeing to give access to his/her card reader of filestorage. Without this consent, all requests will return a 401/404 Unauthorized response with error No valid consent found or at initialisation of the Trust1Connector SDK an error No valid consent found. The application should detect these errors and use it to trigger the consent dialog.

The application shows this code word on screen and provide a button for 'copy-to-clipboard'. When the user has copied the code word to the clipboard (on user click button event), an implicit consent request can be executed towards the T1C. The T1C will grab the pasted code word from the user system clipboard and if both match, an implicit user consent has been granted for the calling application. The relation between the application and the local T1C instance is 'approved'. At this point the Trust1Connector returns a verified consent object that is stored in the browser's localstorage. This object is used to validate the consent and retrieve the necessary information for the Trust1Connector to function. This object will be re-used the next time the user wants to use the Trust1Connector until the consent expires.

Generating a random clipboard value

The clipboard value is a random value that is used to determine which agent you are running. This clipboard value needs to be pseudorandom so that we dont accidently find different agent.

The Javascript has an exposed function that creates this value for you.

The function is statically available on the T1CClient class and has the following interface.

public static generateConsentToken(): string

This will return the randomly generated value as a string value immediatley.

To call this;

# regular imported javascript via script tag
T1CSdk.T1CClient.generateConsentToken()

# Import loaded via NPM
import {T1CClient} from "t1c-sdk-js";

T1CClient.generateConsentToken()

User clipboard remark

Initially the concept was based on copying programmatically the code word, from the application context, to the user system clipboard. Although, through CAB forum, this not allowed; A user interaction is mandatory. The application should provide a 'copy-to-clipboard' button or alike in order to 'trigger' a user action. Once this action has been done, the T1C can be triggered to execute the consent.

Sending an implicit consent request can be done as follows:

T1CSdk.T1CClient.initialize(config).then(res => {
    client = res;
    console.log("Client config: ", client.localConfig)
    core = client.core();
}, err => {
    if (err.code == 814501) {
        console.log(err)
        client = err.client
        $('#consentModal').modal('show', {
            keyboard: false
        });
        $('.consent-token').text(makeid(20));
    } else if(err.code == 815500) {
        // Agent not registered --> contact support
    } else if (err.code == 112999) {
        // Unavailable
    } else {
        console.error("T1C error:", err)
    }
}); 

The code below is an example of a javascript event handler on a consent button.

$('#consentModal .btn-primary').on('click', (ev) => {
    const tokenNode = document.querySelector('.consent-token');
    var range = document.createRange();
    range.selectNode(tokenNode);
    window.getSelection().addRange(range);
    try {
        document.execCommand('copy');
    } catch (err) {
        console.log('Oops, unable to copy');
    }
    window.getSelection().removeRange(range);
    const clipboardData = tokenNode.textContent;
    const validityInDays = 365
    
    client.core().getImplicitConsent(clipboardData, validityInDays).then(consentRes => {
        client = consentRes // replace the client and other set variables of the T1C
        core = client.core();
        core.version().then(versionResult => console.log("T1C running on core " + versionResult));
        $('#consentModal').modal('hide');
    }, err => {
        console.error(err)
    })
});

This call has 1 required and 2 optional parameters:

1. Code Word (required): a code word in string format that will be shown in the consent dialog.

2. Consent duration in days (optional): Allows the application the specify how long this consent is to be valid if granted. If not provided, the default value is 365 days.

3. Callback function (optional): function to be called with the result of the consent request.

The response of the consent will be an updated T1C Client which you after this point can use to continue your use-case(s).

The response can also be a 400 Bad Request with status code 814501 "Invalid consent" or 814500 "No agents registered" which means that the request has been sent with the unique code but the Registry cannot not find the user associated with it by checking the clipboards of all connected users.

This could mean that there is no T1C API client present or it is not running correctly.

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.

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.

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

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"
        ],
        "module": ["beid"]
      },
      "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.

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.

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

Pin-Pad Capabilities

As mentioned, 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)"
        ],
        "module": ["emv"]
      },
      "id": "e5863fcc71478871",
      "name": "Gemalto Ezio Shield Secure Channel",
      "pinpad": true
    },
    {
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": [
          "Belgium Electronic ID card"
        ]
        "module": ["beid"]
      },
      "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 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.

T1CSdk.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
}

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;

export class GCLConfigOptions {
    constructor(public gclUrl?: string,
                public gwOrProxyUrl?: string,
                public apiKey?: string,
                public gwJwt?: string,
                public tokenExchangeContextPath?: string,
                public ocvContextPath?: string,
                public dsContextPath?: string,
                public dsFileContextPath?: string,
                public pkcs11Config?: Pkcs11ModuleConfig,
                public agentPort?: number,
                public implicitDownload?: boolean,
                public forceHardwarePinpad?: boolean,
                public sessionTimeout?: number,
                public consentDuration?: number,
                public consentTimeout?: number,
                public syncManaged?: boolean,
                public osPinDialog?: boolean,
                public containerDownloadTimeout?: number,
                public localTestMode?: boolean,
                public lang?: string,
                public providedContainers?: T1CContainerid[]) {
    }
}

With the v3 this is significantly simplified to the following;

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"
  ) {}
}

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:

config = new GCLLib.GCLConfig(configoptions);
    GCLLib.GCLClient.initialize(config).then(res => {
        client = res;
        core = client.core();
        console.log("GCLClient: ", res)
    }, err => {
        console.log("GCL error:", err)
    })

V3 example;

config = new T1CSdk.T1CConfig(configoptions);
T1CSdk.T1CClient.initialize(config).then(res => {
    client = res;
    console.log("Client config: ", client.localConfig)
    core = client.core();

}, err => {
    errorHandler(err);
});

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)

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.

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.

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):

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 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.

Response:

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

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

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.

Core interface

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

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/downloads/installer endpoint of the Distribution Service (e.g. https://acc-ds.t1t.io/v3/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/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/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/downloads/installers/macos

# ARM64
https://ds.t1t.io/v3/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.

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.

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.

Example response

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 104026 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:

The function's interface is as follows;

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

Introduction

Aventra MyEID PKI Card is a cryptographic smart card conforming to common Public Key Infrastructure standards like ISO/IEC-7816 and PKCS#15v1.0 specification. It can be used for various tasks requiring strong cryptography, e. g. logging securely to Windows, encrypting e-mail, authentication, and electronic signatures. The card is also available as a Dual Interface version, compatible with T=CL protocol and also emulating Mifare™. The card is a JavaCard with Aventra MyEID applet that implements the functionality.

The applet implements the FINEID S1 v1.12 specification and it can be configured to include all or any subset of the features specified in FINEID S4-1 or S4-2 specifications. Starting from version 2.2.0 the applet supports both 1024 and 2048 bit RSA keys. From version 3.0.0 (MyEID3) the applet supports keys from 512 bit up to 2048 bit in increments of 64 bits. The applet is fully compatible with JavaCard 2.1.1 and GlobalPlatform 2.0.1 specifications. The new MyEID version 3 (MyEID3) is now released and it uses the new JavaCard 2.2.1 and GlobalPlatform 2.1.1 platform. The new MyEID3 now supports RSA keys from 512 up to 2048 bits in 64 bit increments. MyEID3 supports file sizes up to 32767 bytes and 14 different PIN-codes can be created and used. The number of RSA keys is only limited by the available memory and maximum numbers of files (see PUT DATA: INITIALISE APPLET).

Examples

Create the Aventra module

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

When initialisation is finished you can continue using the aventra object to execute the functions below.

All certificate filters

aventra.allCertFilters().then(res => {
}, err => {
    console.error(err)
})

The expected response for this call should be;

{
    success: true,
    data: ['rootCertificate', 'authenticationCertificate', 'encryptionCertificate', 'nonRepudiationCertificate', 'issuerCertificate']
}

all Key references

aventra.allKeyRefs().then(res => {
}, err => {
    console.error(err)
})

The expected response for this call should be;

{
    success: true,
    data: ['authenticate', 'sign', 'encrypt']
}

all Certificates

Exposes all the certificates publicly available on the smart card. The following certificates can be found on the card:

• Root certificate

• Signing certificate

• Authentication certificate

• Issuer certificate

• Encryption certificate

When additional parsing of the certificate is needed you can add a boolean to indicate if you want to parse the certificate or not.

const filter = ['rootCertificate', 'authenticationCertificate', 'encryptionCertificate'];
aventra.allCerts(parseCertsBoolean, filter).then(res => {
}, err => {
    console.error(err)
})

The expected response for this call should be;

{
    success: true,
    data: {
       authenticationCertificate?: {
            certificate?: TokenCertificateObject,
            certificates?: Array<TokenCertificateObject>
       },
       citizenCertificate?: {
            certificate?: TokenCertificateObject,
            certificates?: Array<TokenCertificateObject>
       },
       nonRepudiationCertificate?: {
            certificate?: TokenCertificateObject,
            certificates?: Array<TokenCertificateObject>
       },,
       rootCertificate?: {
            certificate?: TokenCertificateObject,
            certificates?: Array<TokenCertificateObject>
       },,
       encryptionCertificate?: {
            certificate?: TokenCertificateObject,
            certificates?: Array<TokenCertificateObject>
       },
    }
}

Token data

This will return information of the Aventra card.

aventra.tokenData().then(res => {
}, err => {
    console.error(err)
})

The expected response for this call should be;

{
    success: true,
    data: {
       version?: string,
       serialNumber?: string,
       label?: string,
       changeCounter?: number,

}, err => {
    console.error(err)
})

Non repudiation certificate

Contains the 'non-repudiation certificate' stored on the smart card. The 'non-repudiation certificate' contains the public key corresponding the private RSA non-repudiation key.

aventra.nonRepudiationCertificate(parseCertsBoolean).then(res => {
}, err => {
    console.error(err)
})

Issuer certificate

aventra.issuerCertificate(parseCertsBoolean).then(res => {
}, err => {
    console.error(err)
})

Encryption certificate

aventra.encryptionCertificate(parseCertsBoolean).then(res => {
}, err => {
    console.error(err)
})

The expected response for these calls should be in the following format;

{
    success: true,
    data: {
        "verfied": true
    }
}

Sign

const data = {
    algorithm: "sha256",
    data: "E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs=",
    id: "123"
}
const bulk = false;
aventra.sign(data, bulk).then(res => {

Introduction

In the Trust1Connector V3 we've completely reworked the error system. The goal of this system is to have error codes which are easy to read, understand and integrate. Our first implementation was a very generic approach with as few error codes as possible.

After some iterations of the Trust1Connector we've discovered that the old error system did not suffice the needs of integrators. So we've upgraded the system to be more consistent and extensive. This provides integrators the flexibility to have a very detailed error handeling system while keeping it easy to understand and read.

The new system provides information about the origin, type and detailed information of the error. We maintained the same type (integers) as our previous error codes, this makes it easier to differentiate them.

Status Codes

T1C uses response codes when handling a request.

In case of an error the response will contain a body with more detailed information about the error:

Error format

Error codes will be in the following number format XXXXXX for example 201010 is an error code that depicts an error occurred with the reader in the Transaction service.

The first digit depicts the Origin of that error, values can be the following;

The following 2 digits describe the type of error;

Finally we have 3 digits that give a more detailed error. These will give you more information about the specific error-case. Currently we have the following exceptions that can be thrown.

Codes to expect

The following list are codes that you can expect.

Simple error handeling

The most simple way you can check the error codes is by only taking into account the latest 3 digits. The first 3 digits provide information about the Context and environment

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).

Biometric data

Contains all card holder related data, excluding the card holder address and photo. The service can be called:

An example callback:

Response:

Address

Contains the card holder's address. The service can be called:

Response:

Picture

Response:

Non-repudiation Certificate

Contains the 'non-repudiation certificate' stored on the smart card. The 'non-repudiation certificate' contains the public key corresponding the private RSA non-repudiation key. When additional parsing of the certificate is needed you can add a boolean to indicate if you want to parse the certificate or not The service can be called:

Response:

Encryption Certificate (RRN)

Contains the 'encryption certificate' stored on the smart card. The 'encryption certificate' corresponds to the private key used to sign the 'biometric' and 'Address' data. When additional parsing of the certificate is needed you can add a boolean to indicate if you want to parse the certificate or not The service can be called:

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:

The 'authenticationreference' property can contain the following values: sha1, sha256, sha512, md5.

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 'algorithm_reference' property can contain the following values: sha1, sha256, sha512, md5.

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.

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

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).

Get valid algorithms to use for Sign or Authenticate

Via the Trust1Connector modules you are able to retrieve available algorithms to use for Signing or Authenticate
