CryptographicEngine.SignHashedDataAsync | signHashedDataAsync method

Applies to Windows and Windows Phone

Signs the hashed input data using the specified key.

Syntax


Windows.Security.Cryptography.Core.CryptographicEngine.signHashedDataAsync(key, data).done( /* Your success and error handlers */ );

Parameters

key

Type: CryptographicKey

The key to use to sign the hash. This key must be an asymmetric key obtained from a PersistedKeyProvider or AsymmetricKeyAlgorithmProvider.

data

Type: IBuffer

The input data to sign. The data is a hashed value which can be obtained through incremental hash.

Return value

Type: IAsyncOperation<IBuffer>

An asynchronous operation to retrieve the signed data.

Remarks

The input data supplied to the SignHashedDataAsync method is a hashed value. To sign raw data that has not been hashed, use the SignAsync method.

If the key is a persisted key and the operation requires UI or takes a long time, use the SignHashedDataAsync method instead of the SignHashedData method.
