    Fields
    name

    string

    Output only. The resource name for this CryptoKey in the format projects/*/locations/*/keyRings/*/cryptoKeys/* .

    primary

    object ( CryptoKeyVersion )

    Output only. A copy of the "primary" CryptoKeyVersion that will be used by cryptoKeys.encrypt when this CryptoKey is given in EncryptRequest.name .

    The CryptoKey 's primary version can be updated via cryptoKeys.updatePrimaryVersion .

    Keys with purpose ENCRYPT_DECRYPT may have a primary. For other keys, this field will be omitted.

    purpose

    enum ( CryptoKeyPurpose )

    Immutable. The immutable purpose of this CryptoKey .

    createTime

    string ( Timestamp format)

    Output only. The time at which this CryptoKey was created.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    nextRotationTime

    string ( Timestamp format)

    At nextRotationTime , 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 cryptoKeyVersions.create and cryptoKeys.updatePrimaryVersion do not affect nextRotationTime .

    Keys with purpose ENCRYPT_DECRYPT support automatic rotation. For other keys, this field must be omitted.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    versionTemplate

    object ( CryptoKeyVersionTemplate )

    A template describing settings for new CryptoKeyVersion instances. The properties of new CryptoKeyVersion instances created by either cryptoKeyVersions.create or auto-rotation are controlled by this template.

    labels

    map (key: string, value: string)

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

    importOnly

    boolean

    Immutable. Whether this key may contain imported versions only.

    destroyScheduledDuration

    string ( Duration format)

    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 30 days.

    A duration in seconds with up to nine fractional digits, ending with ' s '. Example: "3.5s" .

    cryptoKeyBackend

    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.

    keyAccessJustificationsPolicy

    object ( 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.

    Union field rotation_schedule . Controls the rate of automatic rotation. rotation_schedule can be only one of the following:
    rotationPeriod

    string ( Duration format)

    nextRotationTime 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 rotationPeriod is set, nextRotationTime must also be set.

    Keys with purpose ENCRYPT_DECRYPT support automatic rotation. For other keys, this field must be omitted.

    A duration in seconds with up to nine fractional digits, ending with ' s '. Example: "3.5s" .

    CryptoKeyPurpose

    CryptoKeyPurpose describes the cryptographic capabilities of a CryptoKey . A given key can only be used for the operations allowed by its purpose. For more information, see Key purposes .

    Enums
    CRYPTO_KEY_PURPOSE_UNSPECIFIED Not specified.
    ENCRYPT_DECRYPT CryptoKeys with this purpose may be used with cryptoKeys.encrypt and cryptoKeys.decrypt .
    ASYMMETRIC_SIGN CryptoKeys with this purpose may be used with cryptoKeyVersions.asymmetricSign and cryptoKeyVersions.getPublicKey .
    ASYMMETRIC_DECRYPT CryptoKeys with this purpose may be used with cryptoKeyVersions.asymmetricDecrypt and cryptoKeyVersions.getPublicKey .
    RAW_ENCRYPT_DECRYPT CryptoKeys with this purpose may be used with cryptoKeyVersions.rawEncrypt and cryptoKeyVersions.rawDecrypt . This purpose is meant to be used for interoperable symmetric encryption and does not support automatic CryptoKey rotation.
    MAC CryptoKeys with this purpose may be used with cryptoKeyVersions.macSign .
    KEY_ENCAPSULATION CryptoKeys with this purpose may be used with cryptoKeyVersions.getPublicKey and cryptoKeyVersions.decapsulate .

    CryptoKeyVersionTemplate

    A CryptoKeyVersionTemplate specifies the properties to use when creating a new CryptoKeyVersion , either manually with cryptoKeyVersions.create or automatically as a result of auto-rotation.

    JSON representation 
     { 
 "protectionLevel"
