HashDataAsync(Stream, CancellationToken)
- Source:
- SHA256.cs
- Source:
- SHA256.cs
- Source:
- SHA256.cs
Asynchronously computes the hash of a stream using the SHA256 algorithm.
public static System.Threading.Tasks.ValueTask<byte[]> HashDataAsync (System.IO.Stream source, System.Threading.CancellationToken cancellationToken = default);
static member HashDataAsync : System.IO.Stream * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<byte[]>
Public Shared Function HashDataAsync (source As Stream, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Byte())
Parameters
- source
- Stream
The stream to hash.
- cancellationToken
- CancellationToken
The token to monitor for cancellation requests. The default value is None.
Returns
The hash of the data.
Exceptions
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(Stream).

- Source:
- SHA256.cs
- Source:
- SHA256.cs
- Source:
- SHA256.cs
Asynchronously computes the hash of a stream using the SHA256 algorithm.
public static System.Threading.Tasks.ValueTask<int> HashDataAsync (System.IO.Stream source, Memory<byte> destination, System.Threading.CancellationToken cancellationToken = default);
static member HashDataAsync : System.IO.Stream * Memory<byte> * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<int>
Public Shared Function HashDataAsync (source As Stream, destination As Memory(Of Byte), Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Integer)
Parameters
- source
- Stream
The stream to hash.
- 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 SHA256 algorithm always produces a 256-bit hash, or 32 bytes.
-or-
source
does not support reading.
The cancellation token was canceled. This exception is stored into the returned task.
