Reference documentation and code samples for the Google Cloud Binary Authorization V1 Client class SignatureAlgorithm.
Represents a signature algorithm and other information necessary to verify
signatures with a given public key.
This is based primarily on the public key types supported by Tink's
PemKeyType, which is in turn based on KMS's supported signing algorithms.
See https://cloud.google.com/kms/docs/algorithms. In the future, BinAuthz
might support additional public key types independently of Tink and/or KMS.
