KeyFormat(value)Types of public keys formats that are supported. Currently, only
PEM format is supported.
Values:
KEY_FORMAT_UNSPECIFIED (0):
Default unspecified value.
PEM (1):
The key is PEM-encoded as defined in RFC
7468 <https://tools.ietf.org/html/rfc7468>. It can be any
of the following: a PEM-encoded PKCS#1/RFC 3447 RSAPublicKey
structure, an RFC 5280
SubjectPublicKeyInfo <https://tools.ietf.org/html/rfc5280#section-4.1>
or a PEM-encoded X.509 certificate signing request (CSR). If
a
SubjectPublicKeyInfo <https://tools.ietf.org/html/rfc5280#section-4.1>
is specified, it can contain a A PEM-encoded PKCS#1/RFC 3447
RSAPublicKey or a NIST P-256/secp256r1/prime256v1 or P-384
key. If a CSR is specified, it will used solely for the
purpose of extracting the public key. When generated by the
service, it will always be an RFC 5280
SubjectPublicKeyInfo <https://tools.ietf.org/html/rfc5280#section-4.1>
structure containing an algorithm identifier and a key.
