Field	Description
key_id	string Required field. ID of the asymmetric KMS key to update. To get the ID of a asymmetric KMS key use a AsymmetricSignatureKeyService.List request. The maximum string length in characters is 50.
update_mask	google.protobuf.FieldMask Required field. Field mask that specifies which attributes of the asymmetric KMS key are going to be updated.
name	string New name for the asymmetric KMS key. The maximum string length in characters is 100.
description	string New description for the asymmetric KMS key. The maximum string length in characters is 1024.
status	enum Status New status for the asymmetric KMS key. Using the AsymmetricSignatureKeyService.Update method you can only set ACTIVE or INACTIVE status. `CREATING`: The key is being created. `ACTIVE`: The key is active and can be used for encryption and decryption or signature and verification. Can be set to INACTIVE using the [AsymmetricKeyService.Update] method. `INACTIVE`: The key is inactive and unusable. Can be set to ACTIVE using the [AsymmetricKeyService.Update] method.
labels	object (map<string, string>) Custom labels for the asymmetric KMS key as `key:value` pairs. Maximum 64 per key. No more than 64 per resource. The maximum string length in characters for each value is 63. Each value must match the regular expression `[-_0-9a-z]`. The maximum string length in characters for each key is 63. Each key must match the regular expression `[a-z][-_0-9a-z]`.
deletion_protection	bool Flag that inhibits deletion of the asymmetric KMS key

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
created_at	google.protobuf.Timestamp Creation timestamp.
created_by	string ID of the user or service account who initiated the operation.
modified_at	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	UpdateAsymmetricSignatureKeyMetadata Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	AsymmetricSignatureKey The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.

UpdateAsymmetricSignatureKeyMetadata

Field

Description

key_id

string

ID of the key being updated.

AsymmetricSignatureKey

An asymmetric KMS key that may contain several versions of the cryptographic material.

Field	Description
id	string ID of the key.
folder_id	string ID of the folder that the key belongs to.
created_at	google.protobuf.Timestamp Time when the key was created.
name	string Name of the key.
description	string Description of the key.
labels	object (map<string, string>) Custom labels for the key as `key:value` pairs. Maximum 64 per key.
status	enum Status Current status of the key. `CREATING`: The key is being created. `ACTIVE`: The key is active and can be used for encryption and decryption or signature and verification. Can be set to INACTIVE using the [AsymmetricKeyService.Update] method. `INACTIVE`: The key is inactive and unusable. Can be set to ACTIVE using the [AsymmetricKeyService.Update] method.
signature_algorithm	enum AsymmetricSignatureAlgorithm Signature Algorithm ID. `RSA_2048_SIGN_PSS_SHA_256`: RSA-2048 signature with PSS padding and SHA-256 `RSA_2048_SIGN_PSS_SHA_384`: RSA-2048 signature with PSS padding and SHA-384 `RSA_2048_SIGN_PSS_SHA_512`: RSA-2048 signature with PSS padding and SHA-512 `RSA_3072_SIGN_PSS_SHA_256`: RSA-3072 signature with PSS padding and SHA-256 `RSA_3072_SIGN_PSS_SHA_384`: RSA-3072 signature with PSS padding and SHA-384 `RSA_3072_SIGN_PSS_SHA_512`: RSA-3072 signature with PSS padding and SHA-512 `RSA_4096_SIGN_PSS_SHA_256`: RSA-4096 signature with PSS padding and SHA-256 `RSA_4096_SIGN_PSS_SHA_384`: RSA-4096 signature with PSS padding and SHA-384 `RSA_4096_SIGN_PSS_SHA_512`: RSA-4096 signature with PSS padding and SHA-512 `ECDSA_NIST_P256_SHA_256`: ECDSA signature with NIST P-256 curve and SHA-256 `ECDSA_NIST_P384_SHA_384`: ECDSA signature with NIST P-384 curve and SHA-384 `ECDSA_NIST_P521_SHA_512`: ECDSA signature with NIST P-521 curve and SHA-512 `ECDSA_SECP256_K1_SHA_256`: ECDSA signature with SECP256_K1 curve and SHA-256
