Certinomis
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 Certigna module exposed on the Trust1Connector onto your web application.
The middleware of Certinomis has to be installed to be able to fully use the Certinomis token.
Supported version of the middleware is; Windows: 10.6 - 64bit & 32bit MacOS Catalina and Mojave: 10.2.97 (supports up until MacOS 10.15 at the time of integration) MacOS 11 and up:

Interface

1
export interface AbstractCertinomis {
2
allCertFilters(): string[];
3
allKeyRefs(): string[];
4
allCerts(parseCerts?: boolean, filters?: string[] | Options, callback?: (error: T1CLibException, data: TokenAllCertsResponse) => void): Promise<TokenAllCertsResponse>;
5
authenticationCertificate(parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;
6
nonRepudiationCertificate(parseCerts?: boolean, callback?: (error: T1CLibException, data: TokenCertificateResponse) => void): Promise<TokenCertificateResponse>;
7
verifyPin(body: TokenVerifyPinData, callback?: (error: T1CLibException, data: TokenVerifyPinResponse) => void): Promise<TokenVerifyPinResponse>;
8
authenticate(body: TokenAuthenticateOrSignData, callback?: (error: T1CLibException, data: TokenAuthenticateResponse) => void): Promise<TokenAuthenticateResponse>;

allAlgoRefs(callback?: (error: T1CLibException, data: TokenAlgorithmReferencesResponse) => void): Promise<TokenAlgorithmReferencesResponse>
11
resetBulkPin(callback?: (error: T1CLibException, data: BoolDataResponse) => void): Promise<BoolDataResponse>;
12
}
Copied!

Models

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

Initialise the Trust1Connector JS

Initialise a Trust1Connector client with a valid configuration:
1
T1CSdk.T1CClient.initialize(config).then(res => {
2
client = res;
3
}, err => {
4
console.error(error)
5
});
Copied!

Obtain the Reader information

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
// List of reader with cards found
4
],
5
"success": true
6
}
Copied!
Using the generic interface can be done as follows;
1
var client = client.certinomis(selected_reader.id);
Copied!
Because we're using the generic interface we can define the module variable upfront since we know we want to use the certigna integration.

Certificates

Exposes all the certificates publicly available on the smart card.

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:
1
client.authenticationCertificate(parseCertsBoolean, callback);
Copied!
Response:
1
{
2
success: true,
3
data: {
4
certificate?: string,
5
certificates?: Array<string>,
6
certificateType?: string,
7
id?: string,
8
parsedCertificate?: Certificate,
9
parsedCertificates?: Array<Certificate>
10
}
11
}
Copied!

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:
1
client.nonRepudiationCertificate(parseCertsBoolean, callback);
Copied!
Response:
1
{
2
success: true,
3
data: {
4
certificate?: string,
5
certificates?: Array<string>,
6
certificateType?: string,
7
id?: string,
8
parsedCertificate?: Certificate,
9
parsedCertificates?: Array<Certificate>
10
}
11
}
Copied!

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:
1
var filter = [];
2
client.allCerts(parseCerts, { filters: filter}, callback);
Copied!
Response:
1
{
2
success: true,
3
data: {
4
certificate?: string,
5
certificates?: Array<string>,
6
certificateType?: string,
7
id?: string,
8
parsedCertificate?: Certificate,
9
parsedCertificates?: Array<Certificate>
10
}
11
}
Copied!
The filter can be used to ask a list of custom data containers. For example, we want to read only the rootCertificate
1
var filter = ['authenticationCertificate'];
2
client.allCerts({ filters: filter}, callback);
Copied!
Response:
1
{
2
success: true,
3
data: {
4
certificate?: string,
5
certificates?: Array<string>,
6
certificateType?: string,
7
id?: string,
8
parsedCertificate?: Certificate,
9
parsedCertificates?: Array<Certificate>
10
}
11
}
Copied!

Sign Data

To get the certificates necessary for signature validation in your back-end:
1
var filter = null;
2
client.allCerts({ filters: filter}, callback);
Copied!
Response:
1
{
2
"authenticationCertificate": {
3
...
4
},
5
"nonRepudiationCertificate": {
6
...
7
}
8
}
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'.

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":"sha256",
4
"data":"n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg="
5
"osDialog": true
6
}
7
client.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": "sha256",
3
"data":"n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg="
4
"osDialog": false
5
}
6
client.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
client.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
client.resetBulkPin(module).then(res => {
2
}, err => {
3
console.error(err)
4
})
Copied!
Response will look like:
1
{
2
"success": true,
3
"data": true
4
}
Copied!

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

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:
1
var data = {
2
"pin": "...",
3
"algorithm": "sha256",
4
"data":"n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg="
5
}
6
client.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.

Get valid algorithms to use for Sign or Authenticate

Via the Trust1Connector generic modules you are able to retrieve available algorithms to use for Signing or Authenticate
1
client.allAlgoRefs(callback);
Copied!
The response you can expect is a list of algorithms, an example can be found below (the values below are purely examplatory)
1
{
2
"success": true,
3
"data": ["sha256"]
4
}
Copied!
