Updated: Apr 8

Trust1team - Published on : 19/10/2022 - Last update : 26/07/2023

Hello Dear Reader !

Welcome to the Trust1Connector solution evolution, corrections, modifications blog!

Here we discuss what's new in the version 3.6.0

In this blog, you will find a summary of the new features of this major new version. Then in a second part, you will have more information on resolved issues.

Finally, we will talk about what's new in future releases of the Trust1Connector.

Enjoy reading !


Overview of the newly added features

Here is a summary of all the changes made on the Trust1Connector

✅Exposed Camerfirma interface

Camerfima is a new PKCS11 token added to the modules of the Trust1Connector. The Camerfirma token pre-requisites the installation of the Carmerfirma middleware.

✅Exposed Chambersign interface

Chambersign is a new PKCS11 token added to the modules of the Trust1Connector. The Chambersign token pre-requisites the installation of the Chambersign middleware.

✅Token Info endpoint will now returned detailed information when using a PKCS11 token

The token info endpoint has been implemented before only for identity tokens. We have added support for Token Info of the PKCS11 modules. As the response has a different data structure, an additional type has been added for clients to parse the response correctly.

The PKCS11 token info exposes information on the algorithms which can be used for different use cases (digital signature, validation, authentication, ...). In a future release additional functionality will be provided such as: encryption, decryption, key exchange,...

✅Fetch all the certificates on a token including all their information

For the different notification types, many tokens share multiple certificates for a single type. The original interface supported only a single certificate response. To be backwards compatible, those certification function have been adapted to be behave the same as in v3.5.x.

New functions are available to support multiple certificate reponses, they are called: [certificateType]Extended. For PKCS11 tokens the certificate response also returns, besides the base64 encoded certificate and the certificate id, the following properties:

  • issuer

  • subject

  • serial number

  • hash sub pub key

  • hash iss pub key

  • exponent (payment modules)

  • remainder (payment modules)

  • parsed certificate (ASN1 format of the base64 encoded certificate)

You can find an example for certigna here

✅Signed hash validation function exposed for PKCS11 tokens

A new function has been added for all PKCS11 modules called the 'validate' endpoint. This endpoint, when available, can be used to validate a signed hash received after calling the 'sign' function. In an next version a variant of the validation function using OpenSSL will be added for all tokens.

✅PKCS11 migration towards RUST

For the Trust1Connector to support more PKCS11 functionality, the intermediate PKCS11 layer has been removed in preference of a direct PKCS11 LIB integration. FFI is used in RUST to support any library which need to be loaded.

✅Token Algortihm input validation for signing and authentication

Additional guard has been implemented to prevent empty algorithms for the digital signature and validation endpoints. PKCS11 tokens will verify as well if the provided algortihm is exposed as an allowed mechanism for the targetted use case.

✅JCOP3 ATR added

The Trust1Connector can now detec Java Card Object Platform 3 typed cards

✅Select default PKCS11 non-repudation or authentication certificate

When requesting for a signature or an authentication, the correct certificate must be provided. For PKCS11 tokens the certificate id (or reference) can be ommitted. The PKCS11 token will be default pick the first certificate (for the type needed) and use this with the specified mechanism to sign/authenticate.


Overview of resolved bugs

🔺Consent error code update

The consent error code has been updated in the Trust1Connector API library, and t1c-sdk-js clients have no impact on that change

🔺Multi-client support and race condition fix

When using different instances of the Trust1Connector (optionally from another partner) on a Windows system, a port collision could be possible due to a race condition in port assignment upon initialization. Ports are now protected with anti-collision and are salted to make a port less guessable.

🔺Implicit creation of LaunchAgents folder on Mac/OSX

When no LaunchAgents folder was present on the system, the installation procedure creates this folder implicitly.


What's planned for the next releases ?


For future releases, we plan to integrate the following elements :

Tokens :

New features :

  • T1C Dashboard : Trust1Connector will give partners a dashboard so that they can view statistics on usage and installed versions.

  • T1C smaller package size : Trust1Team's R&D seeks to reduce packet size to avoid overloading its partners' disk space.

New support :

  • Windows Mini-Driver : In a future release, the Trust1Connector will have an additional option using the Windows mini driver.

  • Debian and Ubuntu : The both editions of Linux will be included in the Trust1Connector.
