RSA加密的程序-RSA encryption procedure

是当今比较新的算法MD5，比DES和DES5都要加密好，是dll文件，在自己写的程序中加入它，就可以直接用了，全是意接口的形式-Is the relatively new algorithm MD5, should DES5 than DES and encryption, and is a dll file, written in their own process to join it, can be directly used, the interface is intended to form ~ ~ ~ ~

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.
