public enum CryptoKeyVersionAlgorithm

The algorithm of the [CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion], indicating what parameters must be used for each cryptographic operation.

The [GOOGLE_SYMMETRIC_ENCRYPTION][google.cloud.kms.v1.CryptoKeyVersion.CryptoKeyVersionAlgorithm.GOOGLE_SYMMETRIC_ENCRYPTION] algorithm is usable with [CryptoKey.purpose][google.cloud.kms.v1.CryptoKey.purpose] [ENCRYPT_DECRYPT][google.cloud.kms.v1.CryptoKey.CryptoKeyPurpose.ENCRYPT_DECRYPT].

Algorithms beginning with "RSA_SIGN_" are usable with [CryptoKey.purpose][google.cloud.kms.v1.CryptoKey.purpose] [ASYMMETRIC_SIGN][google.cloud.kms.v1.CryptoKey.CryptoKeyPurpose.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][google.cloud.kms.v1.CryptoKey.purpose] [ASYMMETRIC_DECRYPT][google.cloud.kms.v1.CryptoKey.CryptoKeyPurpose.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][google.cloud.kms.v1.CryptoKey.purpose] [ASYMMETRIC_SIGN][google.cloud.kms.v1.CryptoKey.CryptoKeyPurpose.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][google.cloud.kms.v1.CryptoKey.purpose] [MAC][google.cloud.kms.v1.CryptoKey.CryptoKeyPurpose.MAC].

The suffix following "HMAC_" corresponds to the hash algorithm being used (eg. SHA256).
