- 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
An asynchronous operation to retrieve the hashed and signed data.
- Attributes
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.
