文件加密的过滤驱动程序，适用于大部分的文件加密软件

程序实现了大素数的判断和如果不是素数，则其可分解的最小的素数-program of large prime numbers and if the judgment is not prime, then decomposition of the smallest prime number

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.
