Base64 编解码演示程序 -Base64 codec demo program

密码算法速度快于其他密码算法-Cipher faster than other cryptographic algorithms

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。

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection
