Cloud KMS V1 Client - Class CryptoKey (1.23.0)

Reference documentation and code samples for the Cloud KMS V1 Client class CryptoKey.

A CryptoKey represents a logical key that can be used for cryptographic operations.

A CryptoKey is made up of zero or more versions, which represent the actual key material used in cryptographic operations.

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ name string

Output only. The resource name for this CryptoKey in the format projects/*/locations/*/keyRings/*/cryptoKeys/*.
↳ primary Google\Cloud\Kms\V1\CryptoKeyVersion

Output only. A copy of the "primary" CryptoKeyVersion that will be used by Encrypt when this CryptoKey is given in EncryptRequest.name. The CryptoKey's primary version can be updated via UpdateCryptoKeyPrimaryVersion. Keys with purpose ENCRYPT_DECRYPT may have a primary. For other keys, this field will be omitted.
↳ purpose int

Immutable. The immutable purpose of this CryptoKey.
↳ create_time Google\Protobuf\Timestamp

Output only. The time at which this CryptoKey was created.
↳ next_rotation_time Google\Protobuf\Timestamp

At next_rotation_time, the Key Management Service will automatically: 1. Create a new version of this CryptoKey. 2. Mark the new version as primary. Key rotations performed manually via CreateCryptoKeyVersion and UpdateCryptoKeyPrimaryVersion do not affect next_rotation_time. Keys with purpose ENCRYPT_DECRYPT support automatic rotation. For other keys, this field must be omitted.
↳ rotation_period Google\Protobuf\Duration

next_rotation_time will be advanced by this period when the service automatically rotates a key. Must be at least 24 hours and at most 876,000 hours. If rotation_period is set, next_rotation_time must also be set. Keys with purpose ENCRYPT_DECRYPT support automatic rotation. For other keys, this field must be omitted.
↳ version_template Google\Cloud\Kms\V1\CryptoKeyVersionTemplate

A template describing settings for new CryptoKeyVersion instances. The properties of new CryptoKeyVersion instances created by either CreateCryptoKeyVersion or auto-rotation are controlled by this template.
↳ labels array|Google\Protobuf\Internal\MapField

Labels with user-defined metadata. For more information, see Labeling Keys.
↳ import_only bool

Immutable. Whether this key may contain imported versions only.
↳ destroy_scheduled_duration Google\Protobuf\Duration

Immutable. The period of time that versions of this key spend in the DESTROY_SCHEDULED state before transitioning to DESTROYED. If not specified at creation time, the default duration is 24 hours.
↳ crypto_key_backend string

Immutable. The resource name of the backend environment where the key material for all CryptoKeyVersions associated with this CryptoKey reside and where all related cryptographic operations are performed. Only applicable if CryptoKeyVersions have a ProtectionLevel of EXTERNAL_VPC, with the resource name in the format projects/*/locations/*/ekmConnections/*. Note, this list is non-exhaustive and may apply to additional ProtectionLevels in the future.
↳ key_access_justifications_policy Google\Cloud\Kms\V1\KeyAccessJustificationsPolicy

Optional. The policy used for Key Access Justifications Policy Enforcement. If this field is present and this key is enrolled in Key Access Justifications Policy Enforcement, the policy will be evaluated in encrypt, decrypt, and sign operations, and the operation will fail if rejected by the policy. The policy is defined by specifying zero or more allowed justification codes. https://cloud.google.com/assured-workloads/key-access-justifications/docs/justification-codes By default, this field is absent, and all justification codes are allowed.
