- Source:

- Source:

Asynchronously computes the HMAC of a stream using the SHA512 algorithm.

- key
- ReadOnlyMemory<Byte>
The HMAC key.
- source
- Stream
The stream to HMAC.
- cancellationToken
- CancellationToken
The token to monitor for cancellation requests. The default value is None.
Returns
The total number of bytes written to destination.
Exceptions
source is null.
The buffer in destination is too small to hold the calculated hash
size. The SHA512 algorithm always produces a 512-bit hash, or 64 bytes.
-or-
source does not support reading.
The cancellation token was canceled. This exception is stored into the returned task.

- key
- Byte[]
The HMAC key.
- source
- Stream
The stream to HMAC.
- cancellationToken
- CancellationToken
The token to monitor for cancellation requests. The default value is None.
Returns
The HMAC of the data.
Exceptions
key or source is null.
source does not support reading.
The cancellation token was canceled. This exception is stored into the returned task.
Remarks
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by HashData(Byte[], Stream).
