md5算法，实现给一个512bir数据块加密，程序有详细的注释，

A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file. The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.
