Values:
UNSPECIFIED_PUBLIC_KEY_FORMAT (0):
The format has not been specified. This is an
invalid default value and must not be used.
RSA_PEM (3):
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 <https://www.ietf.org/rfc/rfc7518.txt>).
RSA_X509_PEM (1):
As RSA_PEM, but wrapped in an X.509v3 certificate
(RFC5280 <https://www.ietf.org/rfc/rfc5280.txt>),
encoded in base64, and wrapped by
-----BEGIN CERTIFICATE----- and
-----END CERTIFICATE-----.
ES256_PEM (2):
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 <https://www.ietf.org/rfc/rfc7518.txt>). This
curve is defined in OpenSSL <https://www.openssl.org/>
as the prime256v1 curve.
ES256_X509_PEM (4):
As ES256_PEM, but wrapped in an X.509v3 certificate
(RFC5280 <https://www.ietf.org/rfc/rfc5280.txt>__),
encoded in base64, and wrapped by
-----BEGIN CERTIFICATE----- and
-----END CERTIFICATE-----.
