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.

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

Disk Space

The T1C-Proxy (necessary for shared environments only) requires ± 250Mb of space

The T1C-API is installed in user space and also requires ± 250Mb of space for every user.

API Key

All endpoints of the Trust1Connector API are secured and require a JWT to access. To obtain a token, an API key must be exchanged. This API key must be requested from Trust1Team, or created by the customer if they are hosting their own Distribution Service

Operating System

Right now Trust1Conector support two operating systems;

• MacOS 10.9 or higher

• Windows 8.1 or higher

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

When running in a shared environment a cookie is used to store the user's consent, the following cookie will be used:

t1c-agent-proxy

Introduction

The Trust1Connector supports user consent mechanism for applications:

implicit user consent: the user will be provided with a consent token which can be pasted into his clipboard. The T1C-GCL will implicitly retrieve the consent token form the clipboard and perform a verification (the token pasted in the clipboard - form the application context - should match with the token available on the clipboard for the T1C-GCL)

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

If the consent has been enabled 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 Unauthorized response with error code 500 No valid consent found or at initialisation of the Trust1Connector SDK an error code 500 No valid consent found. The application should detect these error codes 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 cookie that should be stored in the browser. This cookie will be re-used the next time the user wants to use the Trust1Connector until the cookie expires.

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 executes the flow automatically, this is retrieval and verification of the code word.

Currently, the need for a user interaction is a known limitation (aka. clipboard.js). As this is the case, the W3C has a project ' Clipboard APIs' to propose a solution for a new clipboard API in browsers. The use case for 'Remote clipboard synchronisation' as a use case included in this draft proposal. As this is a draft, and not yet supported by the browsers, we can not perform an automatic 'paste' ('copy' in terms of the browser) to the clipboard.

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) {
        $('.consent-token').text(makeid(20));
    } else if (err.code == 112999) {
        // General
    } else {
        console.error("T1C error:", err)
    }
});
    

$('#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;
    
    client.core().getImplicitConsent(clipboardData).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 or 814500 "No agents registered to the proxy service" which means that the request has been sent with the unique code but the Proxy 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.

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.

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.

Error while retrieving readers

Is the smartcard service running?

The Smartcard service is a Windows service that manages the connection to the eID and card reader. Therefore, this service must be running for you to be able to access the eID. You can check this as follows:

• Open "Windows Services".

• Search for "Smartcard service" as shown in the following screenshot:

Check the following Smartcard service settings (based on the screenshot above):

• The status column for the Smartcard service shows 'Running'.

• The 'Log On As' column shows 'Local Service'.

Are the Smartcard service settings NOT as they should be? Then do whichever of the following two options applies:

1. The Smartcard service is not running.

Start the Smartcard service, as follows:

• Double-click the Smartcard service.

• Click 'Start' and then 'OK'.

2. The Smartcard service is not logged on as a 'Local Service'.

• Double-click the Smartcard service.

• Select the second tab, 'Log On'.

• Select 'This account'.

• Click 'Browse'.

• In the white text box, type: loc.

• Then click 'Check names'.

• The name 'Local service' now appears in the text box.

• Then click 'OK'.

• Leave the password boxes empty.

• Click 'Apply'.

• Click 'OK'.

• Go back to the first tab, 'General', and restart the service.

• Click 'Start'.

• Click 'Stop'.

DNS probe finished nxdomain error

In some cases there is a possibility that the system is not able to retrieve the domain information, in this case the T1C is not usable. To solve this problem you can follow these steps described here; https://www.hostinger.com/tutorials/fix-dns_probe_finished_nxdomain

Error during installation MSI error 2502 or 2503

When installing the T1C the possibility of the errors 2502 or 2503 originate from the fact that permissions in the temp folder (C:\Windows\Temp) are not correct, and since the MSI installer relies on this they need to be correct. You need to have permissions next to the administrator rights.

You need to have permissions as <My User> next to the administrator rights.

Introduction

The Generic token interface is an interface used to integrate all supported tokens. This interface relies on the fact that you will need to provide a valid module. The module suggested from the reader response can be used here.

Interface

Models

Initialise the Trust1Connector JS

Initialise a Trust1Connector client with a valid configuration:

Obtain the Reader information

In order to get all connected card-readers, with available cards:

This function call returns:

As you can see in the response we get a property suggestedModule which is returned based on the card, reader and AID information. This suggested module can be used in the generic interface.

Using the generic interface can be done as follows;

The pin and pinType are optional and are used for unlocking the pace layer (if the card is protected with a pace layer).

At this point for each use-case you will need to provide the module. This can be manually defined or be retrieved from the suggestedModule property in the reader-response. In the examples below we provide the module as a variable module

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

Contains the card holder's picture stored on the smart card. The service can be called:

Response:

Token info

The token info contains generic information about the card and it's capabilities. This information includes the serial number, file types for object directory files, algorithms implemented on the card, etc.

Response

Certificates

Exposes all the certificates publicly available on the smart card.

Root Certificate

Contains the 'root certificate' stored on the smart card. The root certificate is used to sign the 'citizen CA 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. The service can be called:

Response:

Authentication Certificate

Contains the 'authentication certificate' stored on the smart card. The 'authentication certificate' contains the public key corresponding to the private RSA authentication key. The 'authentication certificate' is needed for pin validation and authentication. 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:

Intermediate Certificate (citizen)

Contains the citizen certificate stored on the smart card. The 'citizen certificate' is used to sign the 'authentication certificate' and the 'non-repudiation 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 The service can be called:

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:

Response:

Data Filter

Filter Card Holder Data

All data on the smart card can be dumped at once, or using a filter. In order to read all data at once:

Response:

The filter can be used to ask a list of custom data containers. For example, we want to read only the biometric data

Response:

Filter Certificates

All certificates on the smart card can be dumped at once, or using a filter. In order to read all certificates at once:

Response:

The filter can be used to ask a list of custom data containers. For example, we want to read only the rootCertificate

Response:

Sign Data

Data can be signed using the Belgian eID smart card. To do so, the T1C-GCL 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'.

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:

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:

Authentication

The T1C-GCL 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.

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

The response you can expect is a list of algorithms, an example can be found below (the values below are purely examplatory)

Integrating the Trust1Connector can be done via the Javascript SDK. This SDK is compiled in regular javascript and in Typescript. Each release of the Javascript SDK will have the following files;

• dist

  • T1CSdk.js (complete SDK)

  • T1CSdk.js.map

• lib (typings, default Typescript compilation)

• lib-esm (typings, Compilation with ES6 module support)

In V3 of the Trust1Connector the javascript SDK is meant as a comparable manner of integrating like the V2. The SDK includes most of the API featureset but not all.

We strongly encourage to integrate via the API, since this will be the most feature-complete and the de-facto way of integration in the future.

Initialising the Trust1Connector

For initialisation of the T1C you need to prepare your application first by adding the SDK JS files to your project and importing them in such a way that you can call for the Javascript functions when you need them.

Next up 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, ...

let environment = {
    t1cApiUrl: 'https://t1c.t1t.io',
    t1cApiPort: '51983',
    t1cProxyUrl: 'https://t1c.t1t.io',
    t1cProxyPort: '51983',
    jwt: '' // retrieve via Back-end
};

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

When the configuration is set you can initialise the Trust1Connector with that Config and an optional property for clipboardData. This clipboard data is used for initialisation of the Trust1Connector in a shared environment. This will be handled later.

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 => {
        else if (err.code == 814501) {
            $('#consentModal').modal('show', {
                keyboard: false
            });
            $('.consent-token').text(makeid(20));
        }
        else if (err.code == 812020) {
            $('.consent-token').text(makeid(20));
        }
        else if(err.code == 112999) {
            document.querySelector("#initAlert").classList.remove("d-none")
            document.querySelector("#initAlert").innerHTML = err.description;
        } else {
            console.error("T1C error:", err)
        }
    });

You can see in the code above we catch 3 errors;

• 814501: Consent error, this means the user is running in a shared environment and needs to provide his consent

• 812020: Initialisation error: The Trust1Connector is not able to initialise because it could not find any users with a Trust1Connector installed.

• 112999: T1C exception, this will be thrown when the T1C is not available, where you can display an URL where the user can download the T1C

Readers

To retrieve the reader after initialisation you can do the following;

core.readersCardAvailable().then(res => {
    //Reader response
}, err => {
    console.log("Cards available error:", err)
})

Initialisation of a module

After initialisation of the T1C you can start using it. For example the BEID module needs to be initialised with a readerId, That is why fetching the readers and providing the user-selected reader to the client is a necessity.

function getBeid() {
    if(selected_reader === null || selected_reader === undefined) return undefined
    else return client.beid(selected_reader.id);
}

The code above will return a BEID client which can be used to execute the BEID functionality.

Shared environments

Initialisation of the Trust1Connector for shared environments is similar to the regular initialisation with the difference being a required consent. More information can be found in the Consent page.

For initialising the Trust1Connector in a shared environment you need to setup the config so that it contacts the Proxy. When initialising you need to provide a token that is residing on the user's clipboard, via this clipboard token the Proxy can determine which which user is trying to communicate and will return an updated configuration value for the API and the sandbox service.

This configuration update is handled by the SDK itself.

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;

The code above is an example of how you can integrate a copy command in the webbrowser

Sample code uses ES6 language features such as arrow functions and promises. For compatibility with IE11, code written with these features must be either transpiled using tools like Babel or refactored accordingly using callbacks.

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.

The JavaScript library must be initialized with a correct token in order to access the all resource. The security policy for Trust1Connector v3 secured ALL endpoints.

Administration resources

Protected resources are administration resources. The JavaScript library must be initialized with a correct token in order to access the resource.

• Download Trust1Connector installer

• Get Information of the device and user context

• Register T1C for device

• Update T1C on device (install new version)

• Update DS (distribution server) metadata

• Increment use case counter

Executing these functionality is explained further.

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

• List modules

• Get module

• Get card-reader

• Get card-reader with cards inserted

• Get card-readers without card

• Get consent (needed for shared environments)

• Detect card for card-reader (polling utility resource)

• Detect any card (polling utility resource)

• Detect card-readers (polling utility resource)

• Browser Information (utility resource)

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, ...

Initialize the client library

The client can be initialized by passing a T1CConfig object in the constructor

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

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

List card readers

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

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"
        ]
      },
      "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.

GCLClient.initialize(config, function(err, client) {
    var coreService = client.core();
    core.readersCardAvailable(callback);
});

Response:

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

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.

Where can I find the installed files

Windows

The Trust1Connector API will be located in %localappdata%/Trust1Connector/ The Trust1Connector Proxy will be located in the %programfiles%/Trust1Connector-Proxy/

MacOS

The API will be located in

~/Library/Application Support/Trust1Team/Trust1Connector/

Do I need administrator rights for installation

For the Trust1Connector API you do not need any administrator rights. The Trust1Connector Proxy requires administrator rights.

How can I manually restart the API?

Windows

You can execute/double click on the following script which will automatically stop and restart the Trust1Connector

%localappdata%/Trust1Connector/t1c-api-sh-env-init.vbs

MacOS

First unload and stop the services. The first is the API and the second is for card communication;

launchctl unload ~/Library/LaunchAgents/com.t1t.t1c.api.plist

launchctl unload ~/Library/LaunchAgents/com.t1t.t1c.grpc.plist

Now load the service again which will make it restart

launchctl load ~/Library/LaunchAgents/com.t1t.t1c.api.plist

launchctl load ~/Library/LaunchAgents/com.t1t.t1c.grpc.plist

Where can i find the log files

Windows

%localappdata%/Trust1Connector/Logs

Macos

~/Library/Application Support/Trust1Team/Trust1Connector/resources/logs

And

~/Library/Application Support/Trust1Team/Trust1Connector/resources/t1c-api/logs

Introduction

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 but we strongly suggest to integrate via the API since the JS SDK does not include all features, only the ones which were available in the v2. When integrating via the API you have more control over the Javascript packages used.

The Javascript SDK has the following packages as dependencies;

"@types/lodash": "^4.14.150",
"Base64": "^1.1.0",
"axios": "^0.19.2",
"jsencrypt": "^3.0.0-rc.1",
"lodash": "^4.17.15",
"logger-bootstrap": "^2.0.0-alpha2",
"semver": "^7.3.2",
"sha256": "^0.2.0",
"store2": "^2.11.1",
"uuid": "^8.0.0"

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;

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

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 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-GCL (Generic Connector Library).

  resetBulkPin(callback?: (error: T1CLibException, data: BoolDataResponse) => void): Promise<BoolDataResponse>;
}

Models

All model information can be found in the Token typings model page

Get Belgian eID container object

Initialise a Trust1Connector client:

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

Get the Belgian eID container service:

var beid = client.beid(reader_id);

Call a function for the Belgian eID container:

function callback(err,data) {
    if(err){console.log("Error:",JSON.stringify(err, null, '  '));}
    else {console.log(JSON.stringify(data, null, '  '));}
}
beid.biometric(callback);

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:

var core = client.core();
core.readersCardAvailable(callback);
