RELATED IDEAS

Support selecting JWT signature and decryption algorithms from JOSE header

See this idea on ideas.ibm.com

For OIDC, mpJwt, etc., the algorithms are currently specified via the configuration in the server.xml or mp config properties file. This limits the configuration of those features to one specific algorithm. If the JWT is signed using a different algorithm, the same configuration cannot be used since it only supports a single algorithm.

Describe the solution you'd like
Allowing an administrator to configure a list of allowed algorithms for an OIDC, mpJwt, etc., the JWT can be signed using one of the allowed algorithms. The JOSE header in the JWT specifies the algorithm to use for verifying the JWT.

Describe alternatives you've considered
Multiple OIDC or mpJwt configs with authFilters
