Reference documentation and code samples for the Google Cloud Key Management Service v1 API class ChecksummedData.
Integrity verification field. A CRC32C
checksum of the returned
[ChecksummedData.data][google.cloud.kms.v1.ChecksummedData.data]. An
integrity check of
[ChecksummedData.data][google.cloud.kms.v1.ChecksummedData.data] can be
performed by computing the CRC32C checksum of
[ChecksummedData.data][google.cloud.kms.v1.ChecksummedData.data] 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.
