CryptoStream.FlushFinalBlock Method


Updates the underlying data source or repository with the current state of the buffer, then clears the buffer.

 void FlushFinalBlock();
public void FlushFinalBlock ();
member this.FlushFinalBlock : unit -> unit
Public Sub FlushFinalBlock ()


The key is corrupt which can cause invalid padding to the stream.

The current stream is not writable.


The final block has already been transformed.


Calling the Close method will call FlushFinalBlock. If you do not call Close, call FlushFinalBlock to complete flushing the buffer. Call FlushFinalBlock only when all stream activity is complete.
