Reference documentation and code samples for the Cloud KMS V1 Client class CryptoKeyVersionAlgorithm.

The algorithm of the CryptoKeyVersion, indicating what parameters must be used for each cryptographic operation.

The GOOGLE_SYMMETRIC_ENCRYPTION algorithm is usable with CryptoKey.purpose ENCRYPT_DECRYPT. Algorithms beginning with RSA_SIGN_ are usable with CryptoKey.purpose ASYMMETRIC_SIGN. The fields in the name after RSA_SIGN_ correspond to the following parameters: padding algorithm, modulus bit length, and digest algorithm. For PSS, the salt length used is equal to the length of digest algorithm. For example, [RSA_SIGN_PSS_2048_SHA256][google.cloud.kms.v1.CryptoKeyVersion.CryptoKeyVersionAlgorithm.RSA_SIGN_PSS_2048_SHA256] will use PSS with a salt length of 256 bits or 32 bytes. Algorithms beginning with RSA_DECRYPT_ are usable with CryptoKey.purpose ASYMMETRIC_DECRYPT. The fields in the name after RSA_DECRYPT_ correspond to the following parameters: padding algorithm, modulus bit length, and digest algorithm. Algorithms beginning with EC_SIGN_ are usable with CryptoKey.purpose ASYMMETRIC_SIGN. The fields in the name after EC_SIGN_ correspond to the following parameters: elliptic curve, digest algorithm. Algorithms beginning with HMAC_ are usable with CryptoKey.purpose MAC. The suffix following HMAC_ corresponds to the hash algorithm being used (eg. SHA256). Algorithms beginning with PQ_ are post-quantum. For more information, see Key purposes and algorithms.
