Reference documentation and code samples for the Cloud Key Management Service (KMS) V1 API module Google::Cloud::Kms::V1::CryptoKeyVersion::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 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).
