             Summary: JWT signed by 1024 bit long key is rejected
                 Key: WFWIP-288
                 URL: https://issues.redhat.com/browse/WFWIP-288
             Project: WildFly WIP
          Issue Type: Bug
          Components: MP JWT
            Reporter: Jan Kasik
            Assignee: Darran Lofthouse


According to MP-JWT 1.1 specification, 1024 and 2048 bit key sizes should be supported. Though when there is JWT signed by 1024 bit long key presented to the server, it is rejected and client receives "Unauthorized" (code 401) message.

See chapter 9.2. Supported Public Key Formats:

{quote}
Support for RSA Public Keys of 1024 or 2048 bits in length is required. Other key sizes are allowed, but should be considered vendor-specific.
