Class RawEncryptRequest (2.23.0)

RawEncryptRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Request message for KeyManagementService.RawEncrypt.

Attributes

Name Description
name str
Required. The resource name of the CryptoKeyVersion to use for encryption.
plaintext bytes
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.
additional_authenticated_data bytes
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.
plaintext_crc32c google.protobuf.wrappers_pb2.Int64Value
Optional. An optional CRC32C checksum of the RawEncryptRequest.plaintext. If specified, KeyManagementService will verify the integrity of the received 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(plaintext) is equal to 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.
additional_authenticated_data_crc32c google.protobuf.wrappers_pb2.Int64Value
Optional. An optional CRC32C checksum of the RawEncryptRequest.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.
initialization_vector bytes
Optional. A customer-supplied initialization vector that will be used for encryption. If it is not provided for AES-CBC and AES-CTR, one will be generated. It will be returned in RawEncryptResponse.initialization_vector.
initialization_vector_crc32c google.protobuf.wrappers_pb2.Int64Value
Optional. An optional CRC32C checksum of the RawEncryptRequest.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.
