Reference documentation and code samples for the Google Cloud Key Management Service v1 API class MacSignResponse.
Response message for
[KeyManagementService.MacSign][google.cloud.kms.v1.KeyManagementService.MacSign].
Integrity verification field. A CRC32C checksum of the returned
[MacSignResponse.mac][google.cloud.kms.v1.MacSignResponse.mac]. An
integrity check of
[MacSignResponse.mac][google.cloud.kms.v1.MacSignResponse.mac] can be
performed by computing the CRC32C checksum of
[MacSignResponse.mac][google.cloud.kms.v1.MacSignResponse.mac] 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.
Property Value
Type
Description
System.Int64
Name
public string Name { get; set; }
The resource name of the
[CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion] used for signing.
Check this field to verify that the intended resource was used for signing.
Integrity verification field. A flag indicating whether
[MacSignRequest.data_crc32c][google.cloud.kms.v1.MacSignRequest.data_crc32c]
was received by
[KeyManagementService][google.cloud.kms.v1.KeyManagementService] and used
for the integrity verification of the
[data][google.cloud.kms.v1.MacSignRequest.data]. A false value of this
field indicates either that
[MacSignRequest.data_crc32c][google.cloud.kms.v1.MacSignRequest.data_crc32c]
was left unset or that it was not delivered to
[KeyManagementService][google.cloud.kms.v1.KeyManagementService]. If you've
set
[MacSignRequest.data_crc32c][google.cloud.kms.v1.MacSignRequest.data_crc32c]
but this field is still false, discard the response and perform a limited
number of retries.
