introspection_ encryption_ alg_ values_ supported
Registry Context
This authorization server metadata field lists the JWE key-encryption algorithms supported by the introspection endpoint for encrypted JWT introspection responses.
Technical Summary
An optional OAuth Authorization Server Metadata parameter containing a JSON array of JWE alg values, as defined by JWA, that the introspection endpoint supports for encrypting the content encryption key of introspection responses.
When Used
Resource servers use this authorization server metadata when parameterizing their client registration requests.
Normative Requirements
Authorization servers
RFC 9701 - Section 7
Publish the supported algorithms for signing and encrypting JWT introspection responses using OAuth 2.0 Authorization Server Metadata parameters..
Authorization servers SHOULD publish the supported algorithms for signing and encrypting the JWT of an introspection response
Unspecified actor
RFC 9701 - Section 7
The introspection_encryption_alg_values_supported parameter is optional and, when present, contains a JSON array of JWE alg values defined in JWA and supported by the introspection endpoint for content key encryption..
OPTIONAL. JSON array containing a list of the JWE encryption algorithms (alg values)
Validation Guidance
If introspection_encryption_alg_values_supported is absent, do not report an error because the parameter is optional.
If introspection_encryption_alg_values_supported is present, verify that it is a JSON array of JWE alg values defined in JWA.
Verify that each listed algorithm is supported by the introspection endpoint for encrypting the content encryption key of introspection responses.
