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 ID-One Cosmo V8-n is part of the Idemia IAS ECC family of cryptographic modules called ID-One Cosmo V8. Modules within this family share the same functionalities and the description of the ID-One Cosmo V8 applies to all versions including the “-n” subject to this validation. This document describes the functionality provided by the Idemia IAS ECC ID-One smartcard - which is a PKI container - on the T1C-GCL (Generic Connector Library) implemented version:
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:
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:
The expected response for these calls should be in the following format;
{ success:true, data: {"verfied": true }}
Sign
Data can be signed using the smartcard. To do so, the SDK facilitates in:
Retrieving the certificate chain (root, intermediate and non-repudiation certificate)
Perform a sign operation (private key stays on the smart card)
Return the signed hash
To sign data, an algorithm must be specified in the algorithm property (see Supported Algorithms), and a Base64-encoded string representation of the digest bytes of the same algorithm in the data property.
Additionally, 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 PIN 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.
The SDK 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
