Public key for the ECDSA algorithm using P-256 and SHA-256, encoded in
base64, and wrapped by -----BEGIN PUBLIC KEY----- and -----END
PUBLIC KEY-----. This can be used to verify JWT tokens with the ES256
algorithm (RFC7518). This curve is
defined in OpenSSL as the prime256v1 curve.
Es256X509Pem
As ES256_PEM, but wrapped in an X.509v3 certificate (RFC5280), encoded in base64, and wrapped by
-----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----.
RsaPem
An RSA public key encoded in base64, and wrapped by
-----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY-----. This can be
used to verify RS256 signatures in JWT tokens (RFC7518).
RsaX509Pem
As RSA_PEM, but wrapped in an X.509v3 certificate (RFC5280), encoded in base64, and wrapped by
-----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----.
UnspecifiedPublicKeyFormat
The format has not been specified. This is an invalid default value and
must not be used.
