IRMA backend packages

irma-backend-packages is a collection of libraries in multiple programming languages assuming the role of the IRMA server in the IRMA protocol, allowing you to integrate IRMA in the backend of your application. In particular, these libraries allow you to do the following:

• Starting IRMA sessions using a session request or a JWT at the IRMA server
• Retrieving the current status of IRMA sessions (only once or by receiving events on status updates)
• Retrieving session result or session result JWT when a session succeeded
• Cancelling IRMA sessions
• Retrieving the JWT public key of the IRMA server
• Generating a JWT of a session request
• Verifying a JWT of a session request or a session result

Additionally, they will handle all communication with the Yivi app.

Depending on the programming language, the libraries achieve this by either directly including the IRMA server functionality, or by consuming the REST API exposed by the irma server.

The library will slightly differ per language, since each programming language has its own conventions.

Available languages

For the list of currently available programming languages, check the GitHub README. (Note that for the Go programming language, there is a separate irmaserver Go package.)

If the programming language of your choice is not available yet, you can always directly invoke the irma server REST API. If you think the programming language of your choice would benefit being part of irma-backend-packages, you can always contact us or make an issue on GitHub.

If you made a library for a programming language yourself that we do not support yet, or if you added features to existing libraries, please send us a pull request. We are always interested in extending the IRMA ecosystem with support for additional programming languages.
