# Generic token

{% hint style="warning" %}
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 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

```javascript
export interface AbstractEidGeneric {
  allData(module: string, filters?: string[] | Options, callback?: (error: T1CLibException, data: TokenAllDataResponse) => void): Promise<TokenAllDataResponse>;
  allCerts(module: string, parseCerts?: boolean,  filters?: string[] | Options, callback?: (error: T1CLibException, data: TokenAllCertsResponse) => void): Promise<TokenAllCertsResponse>;
  biometric(module: string, callback?: (error: T1CLibException, data: TokenBiometricDataResponse) => void): Promise<TokenBiometricDataResponse>;
  tokenData(module: string, callback?: (error: T1CLibException, data: TokenInfoResponse) => void): Promise<TokenInfoResponse>;
  address(module: string, callback?: (error: T1CLibException, data: TokenAddressResponse) => void): Promise<TokenAddressResponse>;
  picture(module: string, callback?: (error: T1CLibException, data: TokenPictureResponse) => void): Promise<TokenPictureResponse>;
  rootCertificate(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;
  intermediateCertificates(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;
  authenticationCertificate(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;
  nonRepudiationCertificate(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;
  encryptionCertificate(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;
  issuerCertificate(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;

  allCertsExtended(module: string, parseCerts?: boolean, filters?: string[] | Options, callback?: (error: T1CLibException, data: TokenAllCertsExtendedResponse) => void): Promise<TokenAllCertsExtendedResponse>;
  rootCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
  intermediateCertificatesExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
  authenticationCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
  nonRepudiationCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
  encryptionCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
  issuerCertificateExtended(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;

  verifyPin(module: string, body: TokenVerifyPinData, callback?: (error: T1CLibException, data: TokenVerifyPinResponse) => void): Promise<TokenVerifyPinResponse>;
  authenticate(module: string, body: TokenAuthenticateOrSignData, callback?: (error: T1CLibException, data: TokenAuthenticateResponse) => void): Promise<TokenAuthenticateResponse>;
  sign(module: string, body: TokenAuthenticateOrSignData, bulk?: boolean, callback?: (error: T1CLibException, data: TokenSignResponse) => void): Promise<TokenSignResponse>;
  signRaw(module: string, body: TokenAuthenticateOrSignData, bulk?: boolean, callback?: (error: T1CLibException, data: TokenSignResponse) => void): Promise<TokenSignResponse>;
  allAlgoRefs(module: string, callback?: (error: T1CLibException, data: TokenAlgorithmReferencesResponse) => void): Promise<TokenAlgorithmReferencesResponse>
  resetBulkPin(module: string, callback?: (error: T1CLibException, data: BoolDataResponse) => void): Promise<BoolDataResponse>;
}
```

### Models

All model information can be found in the [Token typings model page](https://t1t.gitbook.io/t1c-js-guide-v3/3.7.x/token-typing-models#models)

## Initialise the Trust1Connector JS

Initialise a Trust1Connector client with a valid configuration:

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

### Obtain the Reader information

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

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

This function call returns:

```javascript
{
  "data": [
    {
      "card": {
        "atr": "3B9813400AA503010101AD1311",
        "description": ["Belgian eID Card"]
      },
      "id": "57a3e2e71c48cee9",
      "name": "Bit4id miniLector",
      "pinpad": false,
      "suggestedModule": "beid"
    }
  ],
  "success": true
}
```

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;

```javascript
var generic = client.generic(selected_reader.id, pin, pinType);
```

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:

```javascript
generic.biometric(module, options, callback);
```

An example callback:

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

```

Response:

```javascript
{
  "data": "/9j/4AAQSkZJRgABA...59aVpcklSDzyKUTEDGK//9k=",
  "success": true
}
```

### 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

```javascript
{
  "data": {
    "eid_compliant":48,
    "electrical_perso_interface_version":0,
    "electrical_perso_version":3,
    "graphical_perso_version":7,

    "serial_number":"534C494E..1231C",
    "version":0,
    "version_rfu":0
    },
    "success": true
}
```

## Certificates

Exposes all the certificates publicly available on the smart card.

### Extended certificates

You can also fetch the extended versions of the certificates via the functions

```
allCertsExtended(module: string, parseCerts?: boolean, filters?: string[] | Options, callback?: (error: T1CLibException, data: TokenAllCertsExtendedResponse) => void): Promise<TokenAllCertsExtendedResponse>;
rootCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
intermediateCertificatesExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
authenticationCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
nonRepudiationCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
encryptionCertificateExtended(module: string, parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
issuerCertificateExtended(module: string, parseCerts?: boolean,  callback?: (error: T1CLibException, data: TokenCertificateExtendedResponse) => void): Promise<TokenCertificateExtendedResponse>;
```

this has the capabilities to return multiple certificates if the token has multiple of this type.

for a single certificate the response looks like:

```json
{
    "success" : true
    "data" : {
        "certificates": [{
            "certificate"?: string,
            "certificateType"?: string,
            "id"?: string,
            "subject"?: string,
            "issuer"?: string,
            "serialNumber"?: string,
            "url"?: string,
            "hashSubPubKey"?: string,
            "hashIssPubKey"?: string,
            "exponent"?: string,
            "remainder"?: string,
            "parsedCertificate"?: Certificate
        }]
    }
}
```

the `allCertsExtended` returns the following, with the contents of the certificates as the one you can see above;

```json
{
    "success" : true
    "data" : {
        "rootCertificate": {
            "certificates": [...]
        },
        "authenticationCertificate": {
            "certificates": [...]
        },
        "nonRepudiationCertificate": {
            "certificates": [...]
        },
        "intermediateCertificates": {
            "certificates": [...]
        },
        "encryptionCertificate": {
            "certificates": [...]
        }
   }
}
```

### 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:

generic.rootCertificate(module, parseCertsBoolean, callback);
```

Response:

```javascript
{
    success: true,
    data: {
        certificate?: string,
        certificates?: Array<string>,
        certificateType?: string,

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

```javascript
var filter = ['biometric'];
generic.allData(module, { filters: filter }, callback);
```

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:

```javascript
var filter = [];
generic.allCerts(module, parseCerts, { filters: filter}, callback);
```

Response:

```javascript
{
 "rootCertificate": {
 ...
 },
 "authenticationCertificate": {
 ...
 },
 "nonRepudiationCertificate": {
 ...
 },
 "intermediateCertificates": {
 ...
 },
 "encryptionCertificate": {
 ...
 }
}
```

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

```javascript
var filter = ['rootCertificate'];
generic.allCerts(module, { filters: filter}, callback);
```

Response:

```javascript
{
 "rootCertificate": {
  ...
 }
}
```

## 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:

```javascript
var filter = null;
generic.allCerts(module, { filters: filter}, callback);
```

Response:

```javascript
{
 "rootCertificate": {
 ...
 },
 "authenticationCertificate": {
 ...
 },
 "nonRepudiationCertificate": {
 ...
 },
 "intermediateCertificates": {
 ...
 },
 "encryptionCertificate": {
 ...
 }
}
```

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:

```javascript
var data = {
      "pin":"...",
      "algorithm":"sha1",
      "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E=",
      "osDialog": true
}
generic.sign(module, data, callback);
```

Response is a base64 encoded signed hash:

```javascript
{
  "success": true,
  "data": {
    "data" : "W7wqvWA8m9S...="
  }
}
```

### 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:

```javascript
var data = {
      "algorithm":"sha1",
      "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E=",
      "osDialog": false
}
generic.sign(module, data, callback);
```

Response is a base64 encoded signed hash:

```javascript
{
  "success": true,
  "data": {
    "data" : "W7wqvWA8m9S...="
  }
}
```

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

### Raw data signing

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

{% hint style="warning" %}
Trust1Connector only supports SHA2 hashing at this point.

When using SHA3, the Trust1Connector will convert to SHA2 implicitly
{% endhint %}

Below you can find an example

```javascript
var data = {
      "algorithm":"sha256",
      "data":"vl5He0ulthjX+VWNM46QX7vJ8VvXMq2k/Tq8Xq1bwEw=",
      "osDialog": false
}
generic.signRaw(module, data, callback);
```

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

Supported hash functions (SHA2) are;

* SHA256
* SHA384
* SHA512

### Bulk Signing

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](https://t1t.gitbook.io/t1c-js-guide-v3/3.7.x/belgian-eid#bulk-pin-reset) method is called.

{% hint style="danger" %}
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.
{% endhint %}

```javascript
const data = {
    algorithm: "sha256",
    data: "E1uHACbPvhLew0gGmBH83lvtKIAKxU2/RezfBOsT6Vs=",
    pin: "1234"
}
const bulk = true;
generic.sign(module, data, bulk).then(res => {
}, err => {
    console.error(err)
})
```

### Bulk PIN Reset

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

```javascript
generic.resetBulkPin(module).then(res => {
}, err => {
    console.error(err)
})
```

Response will look like:

```javascript
{
    "success": true,
    "data": 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:

```javascript
var data = {
      "pin":"..."
}
generic.verifyPin(module, data, callback);
```

Response:

```javascript
{
  "verified": true
}
```

### 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:

```javascript
var data = {}
generic.verifyPin(module, data, callback);
```

Response:

```javascript
{
  "verified": true
}
```

## Authentication

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:

```javascript
var data = {
  "pin": "...",
  "algorithm": "sha1",
  "data":"I2e+u/sgy7fYgh+DWA0p2jzXQ7E="
}
generic.authenticate(module, data, callback);
```

Response:

```javascript
{
  "success": true,
  "data": {
    "data" : "W7wqvWA8m9S...="
  }
}
```

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

```javascript
generic.allAlgoRefs(module, callback);
```

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

```javascript
{
    "success": true,
    "data": ["sha1", "sha256"]

```
