Instance Methods

asymmetricDecrypt(name, body=None, x__xgafv=None)

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

asymmetricSign(name, body=None, x__xgafv=None)

Signs data using a CryptoKeyVersion with CryptoKey.purpose ASYMMETRIC_SIGN, producing a signature that can be verified with the public key retrieved from GetPublicKey.

close()

Close httplib2 connections.

create(parent, body=None, x__xgafv=None)

Create a new CryptoKeyVersion in a CryptoKey. The server will assign the next sequential id. If unset, state will be set to ENABLED.

destroy(name, body=None, x__xgafv=None)

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.

get(name, x__xgafv=None)

Returns metadata for a given CryptoKeyVersion.

getPublicKey(name, x__xgafv=None)

Returns the public key for the given CryptoKeyVersion. The CryptoKey.purpose must be ASYMMETRIC_SIGN or ASYMMETRIC_DECRYPT.

import_(parent, body=None, x__xgafv=None)

Import wrapped key material into a CryptoKeyVersion. All requests must specify a CryptoKey. If a CryptoKeyVersion is additionally specified in the request, key material will be reimported into that version. Otherwise, a new version will be created, and will be assigned the next sequential id within the CryptoKey.

list(parent, filter=None, orderBy=None, pageSize=None, pageToken=None, view=None, x__xgafv=None)

Lists CryptoKeyVersions.

list_next()

Retrieves the next page of results.

macSign(name, body=None, x__xgafv=None)

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

macVerify(name, body=None, x__xgafv=None)

Verifies MAC tag using a CryptoKeyVersion with CryptoKey.purpose MAC, and returns a response that indicates whether or not the verification was successful.

patch(name, body=None, updateMask=None, x__xgafv=None)

Update a CryptoKeyVersion's metadata. state may be changed between ENABLED and DISABLED using this method. See DestroyCryptoKeyVersion and RestoreCryptoKeyVersion to move between other states.

rawDecrypt(name, body=None, x__xgafv=None)

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

rawEncrypt(name, body=None, x__xgafv=None)

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.

restore(name, body=None, x__xgafv=None)

Restore a CryptoKeyVersion in the DESTROY_SCHEDULED state. Upon restoration of the CryptoKeyVersion, state will be set to DISABLED, and destroy_time will be cleared.

Method Details

asymmetricDecrypt(name, body=None, x__xgafv=None)
Decrypts data that was encrypted with a public key retrieved from GetPublicKey corresponding to a CryptoKeyVersion with CryptoKey.purpose ASYMMETRIC_DECRYPT.

Args:
  name: string, Required. The resource name of the CryptoKeyVersion to use for decryption. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for KeyManagementService.AsymmetricDecrypt.
  "ciphertext": "A String", # Required. The data encrypted with the named CryptoKeyVersion's public key using OAEP.
  "ciphertextCrc32c": "A String", # 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.
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

  "plaintext": "A String", # The decrypted data originally encrypted with the matching public key.
  "plaintextCrc32c": "A String", # Integrity verification field. A CRC32C checksum of the returned AsymmetricDecryptResponse.plaintext. An integrity check of AsymmetricDecryptResponse.plaintext can be performed by computing the CRC32C checksum of AsymmetricDecryptResponse.plaintext and comparing your results to this field. Discard the response in case of non-matching checksum values, and 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.
  "protectionLevel": "A String", # The ProtectionLevel of the CryptoKeyVersion used in decryption.
  "verifiedCiphertextCrc32c": True or False, # Integrity verification field. A flag indicating whether AsymmetricDecryptRequest.ciphertext_crc32c was received by KeyManagementService and used for the integrity verification of the ciphertext. A false value of this field indicates either that AsymmetricDecryptRequest.ciphertext_crc32c was left unset or that it was not delivered to KeyManagementService. If you've set AsymmetricDecryptRequest.ciphertext_crc32c but this field is still false, discard the response and perform a limited number of retries.

import_(parent, body=None, x__xgafv=None)
Import wrapped key material into a CryptoKeyVersion. All requests must specify a CryptoKey. If a CryptoKeyVersion is additionally specified in the request, key material will be reimported into that version. Otherwise, a new version will be created, and will be assigned the next sequential id within the CryptoKey.

Args:
  parent: string, Required. The name of the CryptoKey to be imported into. The create permission is only required on this key when creating a new CryptoKeyVersion. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for KeyManagementService.ImportCryptoKeyVersion.
  "algorithm": "A String", # Required. The algorithm of the key being imported. This does not need to match the version_template of the CryptoKey this version imports into.
  "cryptoKeyVersion": "A 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.
  "importJob": "A String", # Required. The name of the ImportJob that was used to wrap this key material.
  "rsaAesWrappedKey": "A 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.
  "wrappedKey": "A 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 or RSA_OAEP_4096_SHA1_AES_256 or RSA_OAEP_3072_SHA256_AES_256 or RSA_OAEP_4096_SHA256_AES_256), this field must contain the concatenation of: 1. 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. 2. 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 or 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.
