CryptoKeyVersion(mapping=None, *, ignore_unknown_fields=False, **kwargs)A CryptoKeyVersion represents an individual cryptographic key, and the associated key material.
An ENABLED version can be used for cryptographic operations.
For security reasons, the raw cryptographic key material represented by a CryptoKeyVersion can never be viewed or exported. It can only be used to encrypt, decrypt, or sign data when an authorized user or application invokes Cloud KMS.

google.protobuf.timestamp_pb2.Timestamp
Output only. The time this CryptoKeyVersion's key material was destroyed. Only present if state is DESTROYED. |
import_job |
str
Output only. The name of the ImportJob used in the most recent import of this CryptoKeyVersion. Only present if the underlying key material was imported. |
import_time |
google.protobuf.timestamp_pb2.Timestamp
Output only. The time at which this CryptoKeyVersion's key material was most recently imported. |
import_failure_reason |
str
Output only. The root cause of the most recent import failure. Only present if state is IMPORT_FAILED. |
external_protection_level_options |
google.cloud.kms_v1.types.ExternalProtectionLevelOptions
ExternalProtectionLevelOptions stores a group of additional fields for configuring a CryptoKeyVersion that are specific to the EXTERNAL protection level. |
reimport_eligible |
bool
Output only. Whether or not this key version is eligible for reimport, by being specified as a target in ImportCryptoKeyVersionRequest.crypto_key_version. |
Classes
CryptoKeyVersionAlgorithm
CryptoKeyVersionAlgorithm(value)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).
For more information, see Key purposes and algorithms.
CryptoKeyVersionState
CryptoKeyVersionState(value)The state of a CryptoKeyVersion, indicating if it can be used.
CryptoKeyVersionView
CryptoKeyVersionView(value)A view for CryptoKeyVersions. Controls the level of detail returned for CryptoKeyVersions in KeyManagementService.ListCryptoKeyVersions and KeyManagementService.ListCryptoKeys.
