Calling Stream.Flush() does not flush the final block, as you might expect. Only by closing the stream or explicitly calling FlushFinalBlock is the final block, with any padding, encrypted and written to the backing stream. Without this call, the encrypted fx\src\data\System\Data\SqlClient\SqlAeadAes256CbcHmac256Algorithm.cs (1) 357csDecrypt.FlushFinalBlock();.

Step 2 : I encrypt source file data in 10 MB Dominic, the main issue I see with your code is that you are converting the encrypted text to a string using encodings.

As a result the parts are sent with Key Check Values included, as a simple checksum.. It’s not difficult to calculate a KCV value, it’s simply just the encryption of a block of zeros and … 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.
