Decrypted file has the same message as the original except it adds a few letters
(usually 2). For example "abc123" = "abc12343". So far I couldn't find any reason as to why it does this, any help is appreciated
Well, as I said, I create a text file, encrypt it, and when I decrypt it I can notice
that there are some letters added to the original text. I can give you some
examples of what letters it adds, but you can try it out for yourself (I compiled the
code in Visual Studio 2015).
