Integrity verification field. A CRC32C checksum of the returnedMacSignResponse.mac. An integrity check ofMacSignResponse.maccan be performed by computing the CRC32C checksum ofMacSignResponse.macand 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.
↳ verified_data_crc32c
bool
Integrity verification field. A flag indicating whetherMacSignRequest.data_crc32cwas received byKeyManagementServiceand used for the integrity verification of thedata. A false value of this field indicates either thatMacSignRequest.data_crc32cwas left unset or that it was not delivered toKeyManagementService. If you've setMacSignRequest.data_crc32cbut this field is still false, discard the response and perform a limited number of retries.
Check this field to verify that the intended resource was used for signing.
