Cloud KMS V1 Client - Class CryptoKeyVersionAlgorithm (1.15.3)

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). For more information, see Key purposes and algorithms.
