Eherkenning

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 following page describes how you can integrate the Eherkenning module exposed on the Trust1Connector onto your web application.

Middleware of Eherkenning has to be installed to be able to fully use the Eherkenning token.

Supported version of the middleware is; Windows: 3.5.3.0 - 64bit & 32bit MacOS: 3.5.3.0

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

{
    "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;

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

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:

generic.authenticationCertificate(module, parseCertsBoolean, callback);

Response:

{
    success: true,
    data: {
        certificate?: string,
        certificates?: Array<string>,
        certificateType?: string,
        id?: string,
        parsedCertificate?: Certificate,
        parsedCertificates?: Array<Certificate>
    }    
}

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:

generic.nonRepudiationCertificate(module, parseCertsBoolean, callback);

Response:

{
    success: true,
    data: {
        certificate?: string,
        certificates?: Array<string>,
        certificateType?: string,
        id?: string,
        parsedCertificate?: Certificate,
        parsedCertificates?: Array<Certificate>
    }    
}

Encryption Certificate

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:

generic.nonRepudiationCertificate(module, parseCertsBoolean, callback);

Response:

{
    success: true,
    data: {
        certificate?: string,
        certificates?: Array<string>,
        certificateType?: string,
        id?: string,
        parsedCertificate?: Certificate,
        parsedCertificates?: Array<Certificate>
    }    
}

Root Certificate/Issuer Certificate

Contains the 'root certificate' or 'Issuer certificate stored on the smart card. The service can be called:

generic.rootCertificate(module, parseCertsBoolean, callback);

Response:

{
    success: true,
    data: {
        certificate?: string,
        certificates?: Array<string>,
        certificateType?: string,
        id?: string,
        parsedCertificate?: Certificate,
        parsedCertificates?: Array<Certificate>
    }    
}

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

Response:

{
 "authenticationCertificate": {
  ...
 },
 "nonRepudiationCertificate": {
  ...
 },
 "encryptionCertificate": {
  ...
 }
}

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

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

Response:

{
 "authenticationCertificate": {
  ...
 }
}

Sign Data

To get the certificates necessary for signature validation in your back-end:

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

Response:

{
 "authenticationCertificate": {
  ...
 },
 "nonRepudiationCertificate": {
  ...
 }
}

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'.

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.

Trust1Connector only supports SHA2 hashing at this point.

When using SHA3, the Trust1Connector will convert to SHA2 implicitly.

Below you can find an example

var data = {
      "algorithm":"sha256",
      "data":"vl5He0ulthjX+VWNM46QX7vJ8VvXMq2k/Tq8Xq1bwEw=",
      "osDialog": false
}
module.signRaw(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

Sign data 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:

var data = {
      "pin":"...",
      "algorithm":"sha256",
      "data":"n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg="
      "osDialog": true
}
module.sign(data, callback);

Response is a base64 encoded signed hash:

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

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:

var data = {
      "algorithm": "sha256",
      "data":"n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg="
      "osDialog": false
}
module.sign(data, callback);

Response is a base64 encoded signed hash:

{
  "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

Validate signature

The module allows you to call a function on the token that can validate a signature. For this we need to use the validateSignature function. You can call this one via;

const body = {
    "algorithm": 'sha256',
    "hash": '...',
    "signedHash": '...',
    "osDialog": false,
    "id": 'cert_id',
    "pin": 'pin_code',
    "timeout": 120 //timeout in seconds
}
safenet.validateSignature(body).then(response => {
    response.valid
).catch(error => {
    errorHandler(error)}
)

The response of this function will return a valid property that is either true or false.

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