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 Certigna has to be installed to be able to fully use the Certigna token.
Because we're using the generic interface we can define the module variable upfront since we know we want to use the certigna integration.
If you want to use the module directly you can initialise as folows (same functions are available but dont need the module to be included in the called function)
var module =client.certigna(selected_reader.id);
Token info
You can fetch the token information via the function. this will give all the information of the token you need according to the PKCS11 specifications
module.tokenData().then(res => {// see response below})
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:
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:
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.
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
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.
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":"..."}module.verifyPin(data, callback);
Response:
{"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:
var data = {}module.verifyPin(data, callback);
Response:
{"verified": true}
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":"sha256","data":"n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg="}module.authenticate(data, callback);
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
module.allAlgoRefs(callback);
The response you can expect is a list of algorithms, an example can be found below (the values below are purely examplatory)
{"success": true,"data": ["sha256"]}
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;
constbody= {"algorithm":'sha256',"hash":'...',"signedHash":'...',"osDialog":false,"id":'cert_id',"pin":'pin_code',"timeout":120//timeout in seconds}module.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.
