Integrity verification field. A CRC32C checksum of the returnedAsymmetricDecryptResponse.plaintext. An integrity check ofAsymmetricDecryptResponse.plaintextcan be performed by computing the CRC32C checksum ofAsymmetricDecryptResponse.plaintextand 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.

bool
Integrity verification field. A flag indicating whetherAsymmetricDecryptRequest.ciphertext_crc32cwas received byKeyManagementServiceand used for the integrity verification of theciphertext. A false value of this field indicates either thatAsymmetricDecryptRequest.ciphertext_crc32cwas left unset or that it was not delivered toKeyManagementService. If you've setAsymmetricDecryptRequest.ciphertext_crc32cbut this field is still false, discard the response and perform a limited number of retries.
