public static IAsyncOperation<IBuffer> SignHashedDataAsync(CryptographicKey key, IBuffer data);function signHashedDataAsync(key, data)Public Shared Function SignHashedDataAsync (key As CryptographicKey, data As IBuffer) As IAsyncOperation(Of IBuffer)Parameters
- key
- CryptographicKey
The key to use to sign the hash. This key must be an asymmetric key obtained from a PersistedKeyProvider or AsymmetricKeyAlgorithmProvider.
- data
- IBuffer
The input data to sign. The data is a hashed value which can be obtained through incremental hash.
Returns
An asynchronous operation to retrieve the signed data.
- Attributes
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.
