Cryptostream flushfinalblock

You should always explicitly close your CryptoStream object after you are done using it by calling the Clear method. Doing so flushes the underlying stream and causes all remaining blocks of data to be processed by the CryptoStream object.

FlushFinalBlock (); // Convert the decrypted data from a MemoryStream to a byte array byte [] plainBytes = memoryStream.

Pastebin is a website where you can store text online for a set period of time. type CryptoStream = inherit Stream new : stream:Stream * transform:ICryptoTransform * mode:CryptoStreamMode -> CryptoStream member CanRead : bool member CanSeek : bool member CanWrite : bool member Clear : unit -> unit member Flush : unit -> unit member FlushFinalBlock : unit -> unit member HasFlushedFinalBlock : bool First, before I begin anything, I want to point out that cryptography is hard. REALLY hard. There are so many possible points of failure, and those points of failure and methods of attack can change depending on what the purpose of encrypting the data is.
