Belgian eID
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 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

Models

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

Get Belgian eID container object

Initialise a Trust1Connector client:
1
T1CSdk.T1CClient.initialize(config).then(res => {
2
client = res;
3
}, err => {
4
console.error(error)
5
});
Copied!
Get the Belgian eID container service:
1
var beid = client.beid(reader_id);
Copied!
Call a function for the Belgian eID container:
1
function callback(err,data) {
2
if(err){console.log("Error:",JSON.stringify(err, null, ' '));}
3
else {console.log(JSON.stringify(data, null, ' '));}
4
}
5
beid.biometric(callback);
Copied!

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:
1
var core = client.core();
2
core.readersCardAvailable(callback);
Copied!
This function call returns:
1
{
2
"data": [
3
{
4
"card": {
5
"atr": "3B9813400AA503010101AD1311",
6

"id": "57a3e2e71c48cee9",
9
"name": "Bit4id miniLector",
10
"pinpad": false
11
}
12
],
13
"success": true
14
}
Copied!
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:
1
var beid = client.beid(reader_id);
Copied!
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:
1
client.beid(reader_id).biometric(callback);
Copied!
An example callback:
1
function callback(err,data) {
2
if(err){
3
console.log("Error:",JSON.stringify(err, null, ' '));
4
}
5
else {
6
console.log(JSON.stringify(data, null, ' '));

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;

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:
1
var filter = null;
2
client.beid(reader_id).allCerts(parseCerts, { filters: filter}, callback);
Copied!
Response:
1
{
2
"rootCertificate": {
3
...
4
},
5
"authenticationCertificate": {

10
},
11
"intermediateCertificates": {
12
...
13
},
14
"encryptionCertificate": {
15
...
16
}
17
}
Copied!
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.
1
var data = {
2
"pin":"...",
3
"algorithm":"sha1",
4
"data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E=",
5
"osDialog": true,
6
"txId": "1234",
7
"language": "fr"
8
}
9
client.beid(reader_id).sign(data, callback);
Copied!
Crelan card readers only support nl, fr, and de as languages

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:
1
var data = {
2
"pin":"...",
3
"algorithm":"sha1",
4
"data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E=",
5
"osDialog": true
6
}
7
client.beid(reader_id).sign(data, callback);
Copied!
Response is a base64 encoded signed hash:
1
{
2
"success": true,
3
"data": {
4
"data" : "W7wqvWA8m9S...="
5
}
6
}
Copied!
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:
1
var data = {
2
"algorithm":"sha1",
3
"data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E=",
4
"osDialog": false
5
}
6
client.beid(reader_id).sign(data, callback);
Copied!
Response is a base64 encoded signed hash:
1
{
2
"success": true,
3
"data": {
4
"data" : "W7wqvWA8m9S...="
5
}
6
}
Copied!
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

It is possible to bulk sign data without having to re-enter the PIN by adding an optional bulk parameter set to true to the request. Subsequent sign requests will not require the PIN to be re-entered until a request with bulk being set to false is sent, or the Bulk Sign Reset method is called.
When using bulk signing, great care must be taken to validate that the first signature request was successful prior to sending subsequent requests. Failing to do this will likely result in the card being blocked.
1
const data = {
2
algorithm: "sha256",
3
data: "E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs=",
4
pin: "1234"
5
}
6
const bulk = true;
7
beid.sign(data, bulk).then(res => {
8
}, err => {
9
console.error(err)
10
})
Copied!

Bulk PIN Reset

The PIN set for bulk signing can be reset by calling this method.
1
beid.resetBulkPin().then(res => {
2
}, err => {
3
console.error(err)
4
})
Copied!
Response will look like:
1
{
2
"success": true,
3
"data": true
4
}
Copied!

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.
1
This is sample text to demonstrate siging with Belgian eID
Copied!
You can use the following online tool to calculate the SHA256: calculate SHA256
Hexadecimal result:
1
135b870026cfbe12dec348069811fcde5bed28800ac54dbf45ecdf04eb13e95b
Copied!
Notice that the length of the SHA256 is always the same. Now we need to convert the hexadecimal string to a base64-encoded string, another online tool can be used for this example: hex to base64 converter
Base64-encoded result:
1
E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs=
Copied!
Now we can sign the data:
1
var data = {
2
"pin":"...",
3
"algorithm":"sha256",
4
"data":"E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs="
5
}
6
client.beid(reader_id).signData(data, callback);
Copied!
Result:
1
{
2
"success": true,
3
"data": {
4
"data" : "W7wqvWA8m9S...="
5
}
6
}
Copied!
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:
1
var data = {
2
"pin":"..."
3
}
4
client.beid(reader_id).verifyPin(data, callback);
Copied!
Response:
1
{
2
"verified": true
3
}
Copied!

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:
1
var data = {}
2
client.beid(reader_id).verifyPin(data, callback);
Copied!
Response:
1
{
2
"verified": true
3
}
Copied!

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:
1
$("#buttonValidate").on('click', function () {
2
var _body={};
3
_body.pin = $("#psw").val(); //only when no pin-pad available
4
var beid = connector.beid(reader_id);
5
beid.verifyPin(_body, validationCallback);
6
});
Copied!
Note that, when the user has at least one retry left, entering a correct PIN resets the PIN retry status.

Authentication

    md5
    sha1
    sha256

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 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:
    1
    var data = {
    2
    "pin": "...",
    3
    "algorithm": "sha1",
    4
    "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E="
    5
    }
    6
    client.beid(reader_id).authenticate(data, callback);
    Copied!
    Response:
    1
    {
    2
    "success": true,
    3
    "data": {
    4
    "data" : "W7wqvWA8m9S...="
    5
    }
    6
    }
    Copied!
    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).
1
The calculated digest of the hash is prefixed with:
2
DigestInfo ::= SEQUENCE {
3
digestAlgorithm AlgorithmIdentifier,
4
digest OCTET STRING
5
}
6
Make sure this has been taken into consideration in order to validate the signature in a backend process.
