Of the signature and MAC algorithms specified in JSON Web Algorithms

conforming JWT implementations. It is RECOMMENDED that
implementations also support RSASSA-PKCS1-v1_5 with the SHA-256 hash
algorithm ("RS256") and ECDSA using the P-256 curve and the SHA-256
hash algorithm ("ES256"). Support for other algorithms and key sizes
is OPTIONAL.
