GeneXus JWT Module is an independent module that implements the JSON Web Token standard defined in RFC7519

The module is based on Microsoft's System.IdentityModel.Tokens.Jwt library for .Net implementation and Auth0 for Java implementation.

JWT is commonly used to validate information integrity and authenticity, or as a means for authentication. In some cases, it is also used as a guarantee for data confidentiality when the information is also encrypted.

At present, this module doesn't implement data encryption. It implements a signed JWT that is not nested.

This module begins to support nested private claims since GeneXus 16 Upgrade 11.

It does not implement arrays on claims, nested signatures nor specific JSON data types yet.


The module is organized in folders using standard defined categories.

  • JWT - JWT engines for signature and verification, and specific optionals.
  • Utils - Specific utilities to work with the module.
