public sealed class PublicKey : IMessage<PublicKey>, IEquatable<PublicKey>, IDeepCloneable<PublicKey>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Key Management Service v1 API class PublicKey.
The public keys for a given
[CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion]. Obtained via
[GetPublicKey][google.cloud.kms.v1.KeyManagementService.GetPublicKey].
The [name][google.cloud.kms.v1.CryptoKeyVersion.name] of the
[CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion] public key.
Provided here for verification.
Integrity verification field. A CRC32C checksum of the returned
[PublicKey.pem][google.cloud.kms.v1.PublicKey.pem]. An integrity check of
[PublicKey.pem][google.cloud.kms.v1.PublicKey.pem] can be performed by
computing the CRC32C checksum of
[PublicKey.pem][google.cloud.kms.v1.PublicKey.pem] 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.
NOTE: This field is in Beta.

Description
System.Int64
ProtectionLevel
public ProtectionLevel ProtectionLevel { get; set; }
The [ProtectionLevel][google.cloud.kms.v1.ProtectionLevel] of the
[CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion] public key.
public PublicKey.Types.PublicKeyFormat PublicKeyFormat { get; set; }
The [PublicKey][google.cloud.kms.v1.PublicKey] format specified by the
customer through the
[public_key_format][google.cloud.kms.v1.GetPublicKeyRequest.public_key_format]
field.
This field contains the public key (with integrity verification), formatted
according to the
[public_key_format][google.cloud.kms.v1.PublicKey.public_key_format] field.
