Reference documentation and code samples for the Google Cloud Key Management Service v1 API class CryptoKeyVersionTemplate.
A [CryptoKeyVersionTemplate][google.cloud.kms.v1.CryptoKeyVersionTemplate]
specifies the properties to use when creating a new
[CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion], either manually
with
[CreateCryptoKeyVersion][google.cloud.kms.v1.KeyManagementService.CreateCryptoKeyVersion]
or automatically as a result of auto-rotation.
public CryptoKeyVersion.Types.CryptoKeyVersionAlgorithm Algorithm { get; set; }
Required.
[Algorithm][google.cloud.kms.v1.CryptoKeyVersion.CryptoKeyVersionAlgorithm]
to use when creating a
[CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion] based on this
template.
For backwards compatibility, GOOGLE_SYMMETRIC_ENCRYPTION is implied if both
this field is omitted and
[CryptoKey.purpose][google.cloud.kms.v1.CryptoKey.purpose] is
[ENCRYPT_DECRYPT][google.cloud.kms.v1.CryptoKey.CryptoKeyPurpose.ENCRYPT_DECRYPT].
public ProtectionLevel ProtectionLevel { get; set; }
[ProtectionLevel][google.cloud.kms.v1.ProtectionLevel] to use when creating
a [CryptoKeyVersion][google.cloud.kms.v1.CryptoKeyVersion] based on this
template. Immutable. Defaults to
[SOFTWARE][google.cloud.kms.v1.ProtectionLevel.SOFTWARE].
