Cloud KMS V1 Client - Class KeyManagementServiceClient (1.19.0)

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

Service Description: Google Cloud Key Management Service

Manages cryptographic keys and operations using those keys. Implements a REST model with the following objects:

If you are using manual gRPC libraries, see Using gRPC with Cloud KMS.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$keyManagementServiceClient = new KeyManagementServiceClient();
try {
    $formattedName = $keyManagementServiceClient->cryptoKeyVersionName('[PROJECT]', '[LOCATION]', '[KEY_RING]', '[CRYPTO_KEY]', '[CRYPTO_KEY_VERSION]');
    $ciphertext = '...';
    $response = $keyManagementServiceClient->asymmetricDecrypt($formattedName, $ciphertext);
} finally {
    $keyManagementServiceClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

This service has a new (beta) implementation. See Google\Cloud\Kms\V1\Client\KeyManagementServiceClient to use the new surface.

Namespace

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

asymmetricDecrypt

Decrypts data that was encrypted with a public key retrieved from GetPublicKey corresponding to a CryptoKeyVersion with CryptoKey.purpose ASYMMETRIC_DECRYPT.

Parameters
Name	Description
`name`	`string` Required. The resource name of the CryptoKeyVersion to use for decryption.
`ciphertext`	`string` Required. The data encrypted with the named CryptoKeyVersion's public key using OAEP.
`optionalArgs`	`array` Optional.
`↳ ciphertextCrc32c`	`Int64Value` Optional. An optional CRC32C checksum of the AsymmetricDecryptRequest.ciphertext. If specified, KeyManagementService will verify the integrity of the received AsymmetricDecryptRequest.ciphertext using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(AsymmetricDecryptRequest.ciphertext) is equal to AsymmetricDecryptRequest.ciphertext_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

decrypt

Decrypts data that was protected by Encrypt. The CryptoKey.purpose must be ENCRYPT_DECRYPT.

Parameters
Name	Description
`name`	`string` Required. The resource name of the CryptoKey to use for decryption. The server will choose the appropriate version.
`ciphertext`	`string` Required. The encrypted data originally returned in EncryptResponse.ciphertext.
`optionalArgs`	`array` Optional.
`↳ additionalAuthenticatedData`	`string` Optional. Optional data that must match the data originally supplied in EncryptRequest.additional_authenticated_data.
`↳ ciphertextCrc32c`	`Int64Value` Optional. An optional CRC32C checksum of the DecryptRequest.ciphertext. If specified, KeyManagementService will verify the integrity of the received DecryptRequest.ciphertext using this checksum. KeyManagementService will report an error if the checksum verification fails.

destroyCryptoKeyVersion

Schedule a CryptoKeyVersion for destruction.

Upon calling this method, CryptoKeyVersion.state will be set to DESTROY_SCHEDULED, and destroy_time will be set to the time destroy_scheduled_duration in the future. At that time, the state will automatically change to DESTROYED, and the key material will be irrevocably destroyed.

Before the destroy_time is reached, RestoreCryptoKeyVersion may be called to reverse the process.

Parameters
Name	Description
`name`	`string` Required. The resource name of the CryptoKey or CryptoKeyVersion to use for encryption. If a CryptoKey is specified, the server will use its primary version.
`plaintext`	`string` Required. The data to encrypt. Must be no larger than 64KiB. The maximum size depends on the key version's protection_level. For SOFTWARE, EXTERNAL, and EXTERNAL_VPC keys, the plaintext must be no larger than 64KiB. For HSM keys, the combined length of the plaintext and additional_authenticated_data fields must be no larger than 8KiB.
`optionalArgs`	`array` Optional.
`↳ additionalAuthenticatedData`	`string` Optional. Optional data that, if specified, must also be provided during decryption through DecryptRequest.additional_authenticated_data. The maximum size depends on the key version's protection_level. For SOFTWARE, EXTERNAL, and EXTERNAL_VPC keys the AAD must be no larger than 64KiB. For HSM keys, the combined length of the plaintext and additional_authenticated_data fields must be no larger than 8KiB.
`↳ plaintextCrc32c`	`Int64Value` Optional. An optional CRC32C checksum of the EncryptRequest.plaintext. If specified, KeyManagementService will verify the integrity of the received EncryptRequest.plaintext using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(EncryptRequest.plaintext) is equal to EncryptRequest.plaintext_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.

`optionalArgs`	`array` Optional.
`↳ cryptoKeyVersion`	`string` Optional. The optional name of an existing CryptoKeyVersion to target for an import operation. If this field is not present, a new CryptoKeyVersion containing the supplied key material is created. If this field is present, the supplied key material is imported into the existing CryptoKeyVersion. To import into an existing CryptoKeyVersion, the CryptoKeyVersion must be a child of ImportCryptoKeyVersionRequest.parent, have been previously created via ImportCryptoKeyVersion, and be in DESTROYED or IMPORT_FAILED state. The key material and algorithm must match the previous CryptoKeyVersion exactly if the CryptoKeyVersion has ever contained key material.
`↳ wrappedKey`	`string` Optional. The wrapped key material to import. Before wrapping, key material must be formatted. If importing symmetric key material, the expected key material format is plain bytes. If importing asymmetric key material, the expected key material format is PKCS#8-encoded DER (the PrivateKeyInfo structure from RFC 5208). When wrapping with import methods ([RSA_OAEP_3072_SHA1_AES_256][google.cloud.kms.v1.ImportJob.ImportMethod.RSA_OAEP_3072_SHA1_AES_256] or [RSA_OAEP_4096_SHA1_AES_256][google.cloud.kms.v1.ImportJob.ImportMethod.RSA_OAEP_4096_SHA1_AES_256] or [RSA_OAEP_3072_SHA256_AES_256][google.cloud.kms.v1.ImportJob.ImportMethod.RSA_OAEP_3072_SHA256_AES_256] or [RSA_OAEP_4096_SHA256_AES_256][google.cloud.kms.v1.ImportJob.ImportMethod.RSA_OAEP_4096_SHA256_AES_256]), this field must contain the concatenation of: An ephemeral AES-256 wrapping key wrapped with the public_key using RSAES-OAEP with SHA-1/SHA-256, MGF1 with SHA-1/SHA-256, and an empty label. The formatted key to be imported, wrapped with the ephemeral AES-256 key using AES-KWP (RFC 5649). This format is the same as the format produced by PKCS#11 mechanism CKM_RSA_AES_KEY_WRAP. When wrapping with import methods ([RSA_OAEP_3072_SHA256][google.cloud.kms.v1.ImportJob.ImportMethod.RSA_OAEP_3072_SHA256] or [RSA_OAEP_4096_SHA256][google.cloud.kms.v1.ImportJob.ImportMethod.RSA_OAEP_4096_SHA256]), this field must contain the formatted key to be imported, wrapped with the public_key using RSAES-OAEP with SHA-256, MGF1 with SHA-256, and an empty label.
`↳ rsaAesWrappedKey`	`string` Optional. This field has the same meaning as wrapped_key. Prefer to use that field in new work. Either that field or this field (but not both) must be specified.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

macSign

Signs data using a CryptoKeyVersion with CryptoKey.purpose MAC, producing a tag that can be verified by another source with the same key.

Parameters
Name	Description
`name`	`string` Required. The resource name of the CryptoKeyVersion to use for signing.
`data`	`string` Required. The data to sign. The MAC tag is computed over this data field based on the specific algorithm.
`optionalArgs`	`array` Optional.
`↳ dataCrc32c`	`Int64Value` Optional. An optional CRC32C checksum of the MacSignRequest.data. If specified, KeyManagementService will verify the integrity of the received MacSignRequest.data using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(MacSignRequest.data) is equal to MacSignRequest.data_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.

rawDecrypt

Decrypts data that was originally encrypted using a raw cryptographic mechanism. The CryptoKey.purpose must be RAW_ENCRYPT_DECRYPT.

Parameters
Name	Description
`name`	`string` Required. The resource name of the CryptoKeyVersion to use for decryption.
`ciphertext`	`string` Required. The encrypted data originally returned in RawEncryptResponse.ciphertext.
`initializationVector`	`string` Required. The initialization vector (IV) used during encryption, which must match the data originally provided in RawEncryptResponse.initialization_vector.
`optionalArgs`	`array` Optional.
`↳ additionalAuthenticatedData`	`string` Optional. Optional data that must match the data originally supplied in RawEncryptRequest.additional_authenticated_data.
`↳ tagLength`	`int` The length of the authentication tag that is appended to the end of the ciphertext. If unspecified (0), the default value for the key's algorithm will be used (for AES-GCM, the default value is 16).
`↳ ciphertextCrc32c`	`Int64Value` Optional. An optional CRC32C checksum of the RawDecryptRequest.ciphertext. If specified, KeyManagementService will verify the integrity of the received ciphertext using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(ciphertext) is equal to ciphertext_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.
`↳ additionalAuthenticatedDataCrc32c`	`Int64Value` Optional. An optional CRC32C checksum of the RawDecryptRequest.additional_authenticated_data. If specified, KeyManagementService will verify the integrity of the received additional_authenticated_data using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(additional_authenticated_data) is equal to additional_authenticated_data_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.
`↳ initializationVectorCrc32c`	`Int64Value` Optional. An optional CRC32C checksum of the RawDecryptRequest.initialization_vector. If specified, KeyManagementService will verify the integrity of the received initialization_vector using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(initialization_vector) is equal to initialization_vector_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.

rawEncrypt

Encrypts data using portable cryptographic primitives. Most users should choose Encrypt and Decrypt rather than their raw counterparts. The CryptoKey.purpose must be RAW_ENCRYPT_DECRYPT.

Parameters
Name	Description
`name`	`string` Required. The resource name of the CryptoKeyVersion to use for encryption.
`plaintext`	`string` Required. The data to encrypt. Must be no larger than 64KiB. The maximum size depends on the key version's protection_level. For SOFTWARE keys, the plaintext must be no larger than 64KiB. For HSM keys, the combined length of the plaintext and additional_authenticated_data fields must be no larger than 8KiB.
`optionalArgs`	`array` Optional.
`↳ additionalAuthenticatedData`	`string` Optional. Optional data that, if specified, must also be provided during decryption through RawDecryptRequest.additional_authenticated_data. This field may only be used in conjunction with an algorithm that accepts additional authenticated data (for example, AES-GCM). The maximum size depends on the key version's protection_level. For SOFTWARE keys, the plaintext must be no larger than 64KiB. For HSM keys, the combined length of the plaintext and additional_authenticated_data fields must be no larger than 8KiB.

setIamPolicy

Sets the access control policy on the specified resource. Replaces any existing policy.

Can return NOT_FOUND, INVALID_ARGUMENT, and PERMISSION_DENIED errors.

Parameters
Name	Description
`resource`	`string` REQUIRED: The resource for which the policy is being specified. See the operation documentation for the appropriate value for this field.
`policy`	`Google\Cloud\Iam\V1\Policy` REQUIRED: The complete policy to be applied to the `resource`. The size of the policy is limited to a few 10s of KB. An empty policy is a valid policy but certain Cloud Platform services (such as Projects) might reject them.
`optionalArgs`	`array` Optional.
`↳ updateMask`	`FieldMask` OPTIONAL: A FieldMask specifying which fields of the policy to modify. Only the fields in the mask will be modified. If no mask is provided, the following default mask is used: `paths: "bindings, etag"`
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\Cloud\Iam\V1\Policy`

Example

use Google\ApiCore\ApiException;
use Google\Cloud\Iam\V1\Policy;
use Google\Cloud\Kms\V1\KeyManagementServiceClient;

/**
 * @param string $resource REQUIRED: The resource for which the policy is being specified.

testIamPermissions

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Parameters
Name	Description
`resource`	`string` REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.
`permissions`	`string[]` The set of permissions to check for the `resource`. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see IAM Overview.
`optionalArgs`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\Cloud\Iam\V1\TestIamPermissionsResponse`

Example

use Google\ApiCore\ApiException;
use Google\Cloud\Iam\V1\TestIamPermissionsResponse;
use Google\Cloud\Kms\V1\KeyManagementServiceClient;

/**
