Luxembourg ID

Introduction

The Luxembourg ID container facilitates communication with card readers with inserted Luxembourg ID 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 Luxembourg ID container on the T1C-GCL (Generic Connector Library).

Interface Summary

The Abstract Lux eID interface is summarised in the following snippet:

export interface AbstractEidLux {
  allData(filters: string[] | Options, callback?: (error: T1CLibException, data: TokenAllDataResponse) => void): Promise<TokenAllDataResponse>;
  allCerts(parseCerts?: boolean, filters?: string[] | Options, callback?: (error: T1CLibException, data: TokenAllCertsResponse) => void): Promise<TokenAllCertsResponse>;
  biometric(callback?: (error: T1CLibException, data: TokenBiometricDataResponse) => void): Promise<TokenBiometricDataResponse>;
  tokenData(callback?: (error: T1CLibException, data: TokenDataResponse) => void): Promise<TokenDataResponse>;
  address(callback?: (error: T1CLibException, data: TokenAddressResponse) => void): Promise<TokenAddressResponse>;
  picture(callback?: (error: T1CLibException, data: TokenPictureResponse) => void): Promise<TokenPictureResponse>;
  rootCertificate(parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;

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

Each interface will be covered on this wiki, accompanied with example code and response objects.

Models

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

Get Luxembourg ID container object

Initialise a Trust1Connector client:

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

Get the Luxembourg ID container service:

const pin_type = 'can' // can be 'can' or 'pin'
let luxeid = client.luxeid(reader_id, pin, pin_type);

Note that we pass both the reader_id and pin/can and specify the pin_type in this call. Unlike other cards, all communication with the Luxembourg ID card is protected with the PIN or CAN code.

Call a function for the Luxembourg ID container:

luxeid.biometric().then(res => {
}, err => {
});

For demonstration purpose we will use the aforementioned callback, which only outputs the data and eventual error messages. During integration meaningful functionality should be provided.

The pin should be provided in order to instantiate the container. It's is possible to enforce user PIN entry for each function separately. Providing the PIN at instantiation of the container, means that the PIN will be in the browser session - but not persisted - for the lifetime of the container instance within the browser session.

Obtain the Reader-ID

The constructor for the Luxembourg ID 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. 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 = gclClient.core();
core.readersCardAvailable(callback);

This function call returns:

{
  "data": [
    {
      "card": {
        "atr": "3B8F800180318065B0850300EF120FFF82900073",
        "description":["Grand Duchy of Luxembourg / Identity card with LuxTrust certificate (eID)"
      },
      "id": "57a3e2e71c48cee9",
      "name": "iDentiv CL",
      "pinpad": false
    }
  ],
  "success": true
}

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 iDentiv CL, has no pin-pad capabilities, and there is a card detected with given ATR and description "Grand Duchy of Luxembourg...". 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 Luxembourg eID card. This must be done upon instantiation of the container:

var luxeid = client.luxeid(reader_id, pin, pin_type);

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

Cardholder Information

The card holder is the person identified using the Luxembourg 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 Information

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

gclClient.luxeid(reader_id, pin).biometric(callback);

An example callback:

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

Response:

{
  "data": {
    "birthDate": "830819",
    "documentNumber": "SPEC04168",
    "documentType": "ID",
    "firstName": "SPECIMEN",
    "gender": "F",
    "issuingState": "LUX",
    "lastName": "SPECIMEN",
    "nationality": "LUX",
    "validityEndDate": "251116",
    "validityStartDate": "151116"
  },
  "success": true
}

Address

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

gclClient.luxeid(reader_id, pin).address(callback);

Response:

{
  "data": {
    //TBD
  },
  "success": true
}

Picture

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

gclClient.luxeid(reader_id, pin).picture(callback);

Response:

{
  "data": {
    "height": 320,
    "image": "/0//UQAvAAAAAADwAAABQAAAAAAAAAAAAAAA8AAA....uq9eK159DRO61Ufrf9ICA/9k=",
    "width": 240
  },
  "success": true
}

Signature Image

Contains an image of the card holder's signature stored on the smart card. The service can be called:

gclClient.luxeid(reader_id, pin).signatureImage(callback);

Response:

{
  "data": {
    "image": "/0//UQAvAAAAAADwAAABQAAAAAAAAAAAAAAA8AAA....uq9eK159DRO61Ufrf9ICA/9k=",
    "raw_data": "/0//UQAAAAAADwAAARLKEQDAAAAAAAAAAAAAA8AAA....dl42fgr367PCSA321/9k="
  },
  "success": true
}

Certificates

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

Root certificate
Intermediate certificate
Authentication certificate
Non-repudiation certificate

T1C-JS will return the raw base64 certificate, optionally it can also return an object representing the certificate as parsed by PKI.js. To enable parsing, parseCerts must be set to true.

The root and intermediate certificates are both stored as root certificates.

Certificate Chain

Root Certificate

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

gclClient.luxeid(reader_id, pin).rootCertificate({ parseCerts: true }, callback);

Response:

{
  "data": [
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    }
  ],
  "success": true
}

There are 2 root certificates on the card, one is the issuer certificate of the intermediate

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, authentication and singing. The service can be called:

gclClient.luxeid(reader_id, pin).authenticationCertificate({ parseCerts: true }, callback);

Response:

{
  "data": {
    "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
    "parsed": { // parsed certificate object }
  },
  "success": true
}

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. The service can be called:

gclClient.luxeid(reader_id, pin).nonRepudiationCertificate({ parseCerts: true }, callback);

Response:

{
  "data": {
    "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
    "parsed": { // parsed certificate object }
  },
  "success": true
}

Data Filter

Filter Card Holder Information

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

var filter = [];
gclClient.luxeid(reader_id, pin).allData({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "biometric": {
      "birthDate": "830819",
      "documentNumber": "SPEC04168",
      "documentType": "ID",
      "firstName": "SPECIMEN",
      "gender": "F",
      "issuingState": "LUX",
      "lastName": "SPECIMEN",
      "nationality": "LUX",
      "validityEndDate": "251116",
      "validityStartDate": "151116"
    },
    "non_repudiation_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "picture": {
      "height": 320,
      "image": "/0//UQAvAAAAAADwAAABQAAAAAAAAAA...f9ICA/9k=",
      "width": 240
    },
    "root_certificates": [
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      },
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      }
    ]
  },
  "success": true
}

The filter can be used to ask a list of custom data containers. For example, we want to read only the 'rn', 'picture' and 'rrn certificate':

// filter entries := ["authentication-certificate","biometric","non-repudiation-certificate","picture","root-certificates"]
var filter = ["biometric","authentication-certificate"];
gclClient.luxeid(reader_id, pin).allData({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "biometric": {
      "birthDate": "830819",
      "documentNumber": "SPEC04168",
      "documentType": "ID",
        "firstName": "SPECIMEN",
        "gender": "F",
        "issuingState": "LUX",
        "lastName": "SPECIMEN",
        "nationality": "LUX",
        "validityEndDate": "251116",
        "validityStartDate": "151116"
    },
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    }
  },
  "success": true
}

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:

var filter = [];
gclClient.luxeid(reader_id, pin).allCerts({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "non_repudiation_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "root_certificates": [
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      },
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      }
    ]
  },
  "success": true
}

The filter can be used to ask a list of custom data containers. For example, we want to read only the 'root-certificate' and the 'rrn-certificate':

// filter entries := ["authentication-certificate","non-repudiation-certificate","root-certificates"];
var filter = ['authentication-certificate'];
gclClient.luxeid(reader_id, pin).allCerts({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    }
  },
  "success": true
}

Sign Data

Data can be signed using the Luxembourg ID smart card. To do so, the T1C-GCL facilitates in:

Retrieving the certificate chain (root, inetermediate 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:

var filter = ['root-certificates','authentication-certificate','non-repudiaton-certificate'];
gclClient.luxeid(reader_id, pin).allCertificates({ filters: filter, parseCerts: false }, callback);

Response:

{
  "non_repudiation_certificate": {
    "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg=="
  },
  "root_certificates": [
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg=="
    },
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg=="
    }  
  ]
}

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

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

var data = {
      "pin":"...",
      "algorithm_reference":"sha1",
      "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E="
}
gclClient.luxeid(reader_id, pin).signData(data, callback);

Response is a base64 encoded signed hash:

{
  "success": true,
  "data": "W7wqvWA8m9SBALZPxN0qUCZfB1O/WLaM/silenLzSXXmeR+0nzB7hXC/Lc/fMru82m/AAqCuGTYMPKcIpQG6MtZ/SGVpZUA/71jv3D9CatmGYGZc52cpcb7cqOVT7EmhrMtwo/jyUbi/Dy5c8G05owkbgx6QxnLEuTLkfoqsW9Q="
}

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

Avoid using SHA-1: is deprecated on the interface and will not be available in the future

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. You might have noticed the algorithm_reference property provided in the sign request. The algorithm_reference can be one of the values: md5, sha1, sha256, sha512. For example, we want the following text to be signed using sha256:

This is sample text to demonstrate siging with Luxembourg eID

You can use the following online tool to calculate the SHA256: calculate SHA256

Hexadecimal result:

135b870026cfbe12dec348069811fcde5bed28800ac54dbf45ecdf04eb13e95b

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:

E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs=

Now we can sign the data:

var data = {
      "pin":"...",
      "algorithm_reference":"sha256",
      "data":"E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs="
}
gclClient.luxeid(reader_id, pin).signData(data, callback);

Result:

{
  "data": "C7SG5eix1+lzMcZXgL0bCL+rLxKhd8ngrSj6mvlgooWH7CloEU13Rj8QiQHdhHnZgAi4Q0fCMIqAc4dn9uW9OP+MRitimRpYZcaDsGrUehPi/JpOD1e+ko7xKZ67ijUU4KTmG4HXc114oJ7xxx3CGL7TNFfvuEphLbbZa+9IZSSnYDOOENJqhggqqu7paSbLJrxC2zaeMxODKb5WSexHnZH6NnLPl2OmvPTYtxiTUMrLbFRsDRAziF6/VQkgM8/xOm+1/9Expv5DSLRY8RQ+wha6/nMlJjx50JszYIj2aBQKp4AOxPVdPewVGEWF4NF9ffrPLrOA2v2d7t5M4q7yxA==",
  "success": true
}

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:

var data = {
      "pin":"..."
}
gclClient.luxeid(reader_id, pin).verifyPin(data, callback);

Response:

{
  "success": true
}

Verify PIN - retries left

In order to inform a user upon the PIN retries left, the Luxembourg 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:

  $("#buttonValidate").on('click', function () {
      var _body={};
      _body.pin = $("#psw").val(); //only when no pin-pad available
      var luxeid = connector.luxeid(reader_id);
      luxeid.verifyPin(_body, validationCallback);
  });

The following error message will be returned when PIN is wrong:

{
  "code": 103,
  "description": "Wrong pin, 2 tries remaining",
  "success": false
}

After a second wrong PIN verification:

{
  "code": 104,
  "description": "Wrong pin, 1 try remaining",
  "success": false
}

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

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:
```
var data = {
  "pin": "...",
  "algorithm_reference": "sha1",
  "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E="
}
gclClient.luxeid(reader_id, pin).authenticate(data, callback);
```
Response:
```
{
"success": true,
"data": "W7wqvWA8m9SBALZPxN0qUCZfB1O/WLaM/silenLzSXXmeR+0nzB7hXC/Lc/fMru82m/AAqCuGTYMPKcIpQG6MtZ/SGVpZUA/71jv3D9CatmGYGZc52cpcb7cqOVT7EmhrMtwo/jyUbi/Dy5c8G05owkbgx6QxnLEuTLkfoqsW9Q="
}
```
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).

The calculated digest of the hash is prefixed with:
DigestInfo ::= SEQUENCE {
      digestAlgorithm AlgorithmIdentifier,
      digest OCTET STRING
  }
Make sure this has been taken into consideration in order to validate the signature in a backend process.

Models

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

Get Luxembourg ID container object

Initialise a Trust1Connector client:

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

Get the Luxembourg ID container service:

const pin_type = 'can' // can be 'can' or 'pin'
let luxeid = client.luxeid(reader_id, pin, pin_type);

Note that we pass both the reader_id and pin/can and specify the pin_type in this call. Unlike other cards, all communication with the Luxembourg ID card is protected with the PIN or CAN code.

Call a function for the Luxembourg ID container:

luxeid.biometric().then(res => {
}, err => {
});

For demonstration purpose we will use the aforementioned callback, which only outputs the data and eventual error messages. During integration meaningful functionality should be provided.

Obtain the Reader-ID

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

This function call returns:

{
  "data": [
    {
      "card": {
        "atr": "3B8F800180318065B0850300EF120FFF82900073",
        "description":["Grand Duchy of Luxembourg / Identity card with LuxTrust certificate (eID)"
      },
      "id": "57a3e2e71c48cee9",
      "name": "iDentiv CL",
      "pinpad": false
    }
  ],
  "success": true
}

var luxeid = client.luxeid(reader_id, pin, pin_type);

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

Cardholder Information

Biometric Information

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

gclClient.luxeid(reader_id, pin).biometric(callback);

An example callback:

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

Response:

{
  "data": {
    "birthDate": "830819",

    "raw_data": "/0//UQAAAAAADwAAARLKEQDAAAAAAAAAAAAAA8AAA....dl42fgr367PCSA321/9k="
  },
  "success": true
}

Certificates

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

Root certificate
Intermediate certificate
Authentication certificate
Non-repudiation certificate

T1C-JS will return the raw base64 certificate, optionally it can also return an object representing the certificate as parsed by PKI.js. To enable parsing, parseCerts must be set to true.

The root and intermediate certificates are both stored as root certificates.

Certificate Chain

Root Certificate

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

gclClient.luxeid(reader_id, pin).rootCertificate({ parseCerts: true }, callback);

Response:

{
  "data": [
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    }
  ],
  "success": true
}

There are 2 root certificates on the card, one is the issuer certificate of the intermediate

Authentication Certificate

gclClient.luxeid(reader_id, pin).authenticationCertificate({ parseCerts: true }, callback);

Response:

{
  "data": {
    "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
    "parsed": { // parsed certificate object }
  },
  "success": true
}

Non-repudiation Certificate

gclClient.luxeid(reader_id, pin).nonRepudiationCertificate({ parseCerts: true }, callback);

Response:

{
  "data": {
    "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
    "parsed": { // parsed certificate object }
  },
  "success": true
}

Data Filter

Filter Card Holder Information

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

var filter = [];
gclClient.luxeid(reader_id, pin).allData({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "biometric": {
      "birthDate": "830819",
      "documentNumber": "SPEC04168",
      "documentType": "ID",
      "firstName": "SPECIMEN",
      "gender": "F",
      "issuingState": "LUX",
      "lastName": "SPECIMEN",
      "nationality": "LUX",
      "validityEndDate": "251116",
      "validityStartDate": "151116"
    },
    "non_repudiation_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "picture": {
      "height": 320,
      "image": "/0//UQAvAAAAAADwAAABQAAAAAAAAAA...f9ICA/9k=",
      "width": 240
    },
    "root_certificates": [
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      },
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      }
    ]
  },
  "success": true
}

The filter can be used to ask a list of custom data containers. For example, we want to read only the 'rn', 'picture' and 'rrn certificate':

// filter entries := ["authentication-certificate","biometric","non-repudiation-certificate","picture","root-certificates"]
var filter = ["biometric","authentication-certificate"];
gclClient.luxeid(reader_id, pin).allData({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "biometric": {
      "birthDate": "830819",
      "documentNumber": "SPEC04168",
      "documentType": "ID",
        "firstName": "SPECIMEN",
        "gender": "F",
        "issuingState": "LUX",
        "lastName": "SPECIMEN",
        "nationality": "LUX",
        "validityEndDate": "251116",
        "validityStartDate": "151116"
    },
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    }
  },
  "success": true
}

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:

var filter = [];
gclClient.luxeid(reader_id, pin).allCerts({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "non_repudiation_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    },
    "root_certificates": [
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      },
      {
        "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
        "parsed": { // parsed certificate object }
      }
    ]
  },
  "success": true
}

The filter can be used to ask a list of custom data containers. For example, we want to read only the 'root-certificate' and the 'rrn-certificate':

// filter entries := ["authentication-certificate","non-repudiation-certificate","root-certificates"];
var filter = ['authentication-certificate'];
gclClient.luxeid(reader_id, pin).allCerts({ filters: filter, parseCerts: true }, callback);

Response:

{
  "data": {
    "authentication_certificate": {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg==",
      "parsed": { // parsed certificate object }
    }
  },
  "success": true
}

Sign Data

Data can be signed using the Luxembourg ID smart card. To do so, the T1C-GCL facilitates in:

Retrieving the certificate chain (root, inetermediate 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:

var filter = ['root-certificates','authentication-certificate','non-repudiaton-certificate'];
gclClient.luxeid(reader_id, pin).allCertificates({ filters: filter, parseCerts: false }, callback);

Response:

{
  "non_repudiation_certificate": {
    "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg=="
  },
  "root_certificates": [
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg=="
    },
    {
      "base64": "MIIFjjCCA3agAwI...rTBDdrlEWVaLrY+M+xeIctrC0WnP7u4xg=="
    }  
  ]
}

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

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

var data = {
      "pin":"...",
      "algorithm_reference":"sha1",
      "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E="
}
gclClient.luxeid(reader_id, pin).signData(data, callback);

Response is a base64 encoded signed hash:

{
  "success": true,
  "data": "W7wqvWA8m9SBALZPxN0qUCZfB1O/WLaM/silenLzSXXmeR+0nzB7hXC/Lc/fMru82m/AAqCuGTYMPKcIpQG6MtZ/SGVpZUA/71jv3D9CatmGYGZc52cpcb7cqOVT7EmhrMtwo/jyUbi/Dy5c8G05owkbgx6QxnLEuTLkfoqsW9Q="
}

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

Avoid using SHA-1: is deprecated on the interface and will not be available in the future

Calculate Hash

This is sample text to demonstrate siging with Luxembourg eID

You can use the following online tool to calculate the SHA256: calculate SHA256

Hexadecimal result:

135b870026cfbe12dec348069811fcde5bed28800ac54dbf45ecdf04eb13e95b

Base64-encoded result:

E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs=

Now we can sign the data:

var data = {
      "pin":"...",
      "algorithm_reference":"sha256",
      "data":"E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs="
}
gclClient.luxeid(reader_id, pin).signData(data, callback);

Result:

{
  "data": "C7SG5eix1+lzMcZXgL0bCL+rLxKhd8ngrSj6mvlgooWH7CloEU13Rj8QiQHdhHnZgAi4Q0fCMIqAc4dn9uW9OP+MRitimRpYZcaDsGrUehPi/JpOD1e+ko7xKZ67ijUU4KTmG4HXc114oJ7xxx3CGL7TNFfvuEphLbbZa+9IZSSnYDOOENJqhggqqu7paSbLJrxC2zaeMxODKb5WSexHnZH6NnLPl2OmvPTYtxiTUMrLbFRsDRAziF6/VQkgM8/xOm+1/9Expv5DSLRY8RQ+wha6/nMlJjx50JszYIj2aBQKp4AOxPVdPewVGEWF4NF9ffrPLrOA2v2d7t5M4q7yxA==",
  "success": true
}

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:

var data = {
      "pin":"..."
}
gclClient.luxeid(reader_id, pin).verifyPin(data, callback);

Response:

{
  "success": true
}

Verify PIN - retries left

  $("#buttonValidate").on('click', function () {
      var _body={};
      _body.pin = $("#psw").val(); //only when no pin-pad available
      var luxeid = connector.luxeid(reader_id);
      luxeid.verifyPin(_body, validationCallback);
  });

The following error message will be returned when PIN is wrong:

{
  "code": 103,
  "description": "Wrong pin, 2 tries remaining",
  "success": false
}

After a second wrong PIN verification:

{
  "code": 104,
  "description": "Wrong pin, 1 try remaining",
  "success": false
}

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

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:
```
var data = {
  "pin": "...",
  "algorithm_reference": "sha1",
  "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E="
}
gclClient.luxeid(reader_id, pin).authenticate(data, callback);
```
Response:
```
{
"success": true,
"data": "W7wqvWA8m9SBALZPxN0qUCZfB1O/WLaM/silenLzSXXmeR+0nzB7hXC/Lc/fMru82m/AAqCuGTYMPKcIpQG6MtZ/SGVpZUA/71jv3D9CatmGYGZc52cpcb7cqOVT7EmhrMtwo/jyUbi/Dy5c8G05owkbgx6QxnLEuTLkfoqsW9Q="
}
```
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).

The calculated digest of the hash is prefixed with:
DigestInfo ::= SEQUENCE {
      digestAlgorithm AlgorithmIdentifier,
      digest OCTET STRING
  }
Make sure this has been taken into consideration in order to validate the signature in a backend process.
