SHA算法的Emule实现

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.

不错的希尔代码，希尔是一种经典的加密算法，加密可以通过一线形变换，脱密再做依次逆变换。密钥就是变换矩阵本身。-good code Hill, Hill is a classic encryption algorithms, encryption can transform line shape, followed again from close inverse transform. Key is the transformation matrix itself.

本软件设计一共分为两个模块：打包加密模块和发行模块。Ø  打包加密模块：实现视频文件的打包加密，音频文件的打包，CPL文件生成，PKL文件生成和创建一个本地资产映射文件MAP.asmap(管理有关影片及密钥相关信息用于发行)。Ø  发行模块：读取MAP.asmap中内容，根据encrypt一项判断视频是否加密。若加密根据MAP.asmap中相关内容和要发行的机器证书文件生成KDM文件和ASSETMAP，若未加密则只生成ASSETMAP文件。
