Edit

Computes a hash for the supplied input data, and then signs the computed hash using the specified key.

public:
 static IAsyncOperation<IBuffer ^> ^ SignAsync(CryptographicKey ^ key, IBuffer ^ data);

/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncOperation<IBuffer> SignAsync(CryptographicKey const& key, IBuffer const& data);

[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncOperation<IBuffer> SignAsync(CryptographicKey key, IBuffer data);

function signAsync(key, data)

Public Shared Function SignAsync (key As CryptographicKey, data As IBuffer) As IAsyncOperation(Of IBuffer)

Parameters

key: CryptographicKey

The key to use to compute and sign the hash.

data: IBuffer

The raw input data to sign. The data is not hashed.

Returns

IAsyncOperation<IBuffer>

An asynchronous operation to retrieve the hashed and signed data.

Attributes: RemoteAsyncAttribute

Remarks

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

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