Reference documentation and code samples for the KMS Inventory 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).
