[Original] Des encryption and decryption program released in 2.0

The des class was rewritten this afternoon. I personally feel that both performance and code optimization have greatly improved compared with version 1.0. However, due to the rush of time, there will inevitably be omissions, welcome to hero Debug. I am not very grateful to you, younger brother.

It took me one afternoon to sell the seller first. Today, I will provide an EXE for downloading the code. I will post the code tomorrow and share it with you. I hope you can have a friend to give feedback on some bugs, I 'd like to optimize it. file encryption and other versions of Version 2.1 are not difficult to add. If some friends are eager to ask for it, I will post the code to you tomorrow, call several functions in the yxydes2 class to complete the operation. HOHO is now at, so it is hard to get stuck.

Note: yxydes2 class is written in standard C ++ and is common in various compilers (vc6.0 console program, Borland C ++ Builder 6.0, vs2008 MFC ), you can even extract all the methods in the class and write them into the C language version.
