Resource: 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.

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 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

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 CreateCryptoKeyVersion and UpdateCryptoKeyPrimaryVersion 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 CreateCryptoKeyVersion 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/*. Only applicable if CryptoKeyVersions have a ProtectionLevel of HSM_SINGLE_TENANT, with the resource name in the format projects/*/locations/*/singleTenantHsmInstances/*. Note, this list is non-exhaustive.
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. If the keyAccessJustificationsPolicy.allowed_access_reasons is empty (zero allowed justification code), all encrypt, decrypt, and sign operations will fail.
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".
