SqlColumnEncryptionKeyStoreProvider.SignColumnMasterKeyMetadata Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
When implemented in a derived class, digitally signs the column master key metadata with the column master key referenced by the masterKeyPath
parameter. The input values used to generate the signature should be the specified values of the masterKeyPath
and allowEnclaveComputations
parameters.
public:
virtual cli::array <System::Byte> ^ SignColumnMasterKeyMetadata(System::String ^ masterKeyPath, bool allowEnclaveComputations);
public virtual byte[] SignColumnMasterKeyMetadata (string masterKeyPath, bool allowEnclaveComputations);
abstract member SignColumnMasterKeyMetadata : string * bool -> byte[]
override this.SignColumnMasterKeyMetadata : string * bool -> byte[]
Public Overridable Function SignColumnMasterKeyMetadata (masterKeyPath As String, allowEnclaveComputations As Boolean) As Byte()
Parameters
- masterKeyPath
- String
The column master key path.
- allowEnclaveComputations
- Boolean
true
to indicate that the column master key supports enclave computations; otherwise, false
.
Returns
The signature of the column master key metadata.
Exceptions
In all cases.
Remarks
To ensure that the SignColumnMasterKeyMetadata method doesn't break applications that rely on an old API, it throws a NotImplementedException exception by default.
The SignColumnMasterKeyMetadata method will be used by client tools that generate Column Master Keys (CMK) for customers. SignColumnMasterKeyMetadata must be implemented by the corresponding key store providers that wish to use enclaves with Always Encrypted.
