public sealed class AsymmetricSignRequest : IMessage<AsymmetricSignRequest>, IEquatable<AsymmetricSignRequest>, IDeepCloneable<AsymmetricSignRequest>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Key Management Service v1 API class AsymmetricSignRequest.
Request message for
[KeyManagementService.AsymmetricSign][google.cloud.kms.v1.KeyManagementService.AsymmetricSign].
Optional. An optional CRC32C checksum of the
[AsymmetricSignRequest.data][google.cloud.kms.v1.AsymmetricSignRequest.data].
If specified,
[KeyManagementService][google.cloud.kms.v1.KeyManagementService] will
verify the integrity of the received
[AsymmetricSignRequest.data][google.cloud.kms.v1.AsymmetricSignRequest.data]
using this checksum.
[KeyManagementService][google.cloud.kms.v1.KeyManagementService] will
report an error if the checksum verification fails. If you receive a
checksum error, your client should verify that
CRC32C([AsymmetricSignRequest.data][google.cloud.kms.v1.AsymmetricSignRequest.data])
is equal to
[AsymmetricSignRequest.data_crc32c][google.cloud.kms.v1.AsymmetricSignRequest.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.

Description
System.Int64
Digest
public Digest Digest { get; set; }
Optional. The digest of the data to sign. The digest must be produced with
the same digest algorithm as specified by the key version's
[algorithm][google.cloud.kms.v1.CryptoKeyVersion.algorithm].
This field may not be supplied if
[AsymmetricSignRequest.data][google.cloud.kms.v1.AsymmetricSignRequest.data]
is supplied.
Optional. An optional CRC32C checksum of the
[AsymmetricSignRequest.digest][google.cloud.kms.v1.AsymmetricSignRequest.digest].
If specified,
[KeyManagementService][google.cloud.kms.v1.KeyManagementService] will
verify the integrity of the received
[AsymmetricSignRequest.digest][google.cloud.kms.v1.AsymmetricSignRequest.digest]
using this checksum.
[KeyManagementService][google.cloud.kms.v1.KeyManagementService] will
report an error if the checksum verification fails. If you receive a
