计算卡片过程密钥，加密密码数据，计算安全报文鉴别（MAC）过程密钥 (Calculating card key, the encrypted password data, calculate the safety message authentication (MAC) key)

图像加密算法,很不错的东东。包含图像基本的加密算法(image cryption)

Hideseek可将秘密文件隐写到指定图片中，并可检测隐写信息，本文是对该软件的使用说明。(hide &seek to run the file through individual test run normally. Hidden secret documents can be written to the specified picture, and can detect steganographic message.)

说明：  vb 加密解密程序 动态加密使用非常方便...(vb encryption and decryption process is very convenient to use dynamic encryption ...)

本源代码，综合了DES，RSA,MD5等几种加密的方法于同一工程中，可以让读者对各种加密方法的实现通过代码实现过程的比较，更好的理解几种软件加密方法(Source code, a combination of DES, RSA, MD5 encryption method, such as several in the same project, will allow readers to a variety of encryption methods to achieve the realization of the process through code comparison, a better understanding of several software encryption methods)

通过调用openssl库进行aes加密，本程序已编译好了openssl，无需在进行编译！生成时请引用lib文件(By calling the openssl library aes encryption, the program has compiled the openssl, without making compilation! Please cite lib files generated)

通过MATLAB的编程，实现对图片的加密，奇异值的分解，离散变化，程序简单，明了。(Through MATLAB programming, realize the image encryption, singular value decomposition and discrete changes, procedure is simple, clear.)

pdf文件加密移除小软件。使pdf文件可打印可注释。(To remove pdf file encryption. So files can be printed comments)

基于RSA算法的加密解密以及数字签名系统，实现加密解密签名的功能(RSA-based encryption and decryption algorithms and digital signature system to achieve the function of signature encryption and decryption )

今天我们学习了des对称加密算法这是一个des算法的C++实现(This is a des !)
