文件加密技术的程序-file encryption procedures

aes 算法的DEMO-Aes algorithm DEMO

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.

The Advanced Encryption Standard (AES) specifies a FIPS- approved cryptographic algorithm that can be used to protect electronic data.  The AES-128 pipelined cipher module uses AES algorithm which is a symmetric block cipher to encrypt (encipher) information. This module is optimized for speed as it pipeline hardware to perform repeated sequence called round
