说明：  一个移位加密算法的源代码，跟大家交流一下。(a shift encryption algorithm source code sharing with you what.)

基于vc++的音频加密软件的设计通过查阅资料对当今比较广泛使用的音频加密算法进行选择，并对其中的三种算法进行其性能方面的比较，找出其中加密性能较好(Audio encryption software design based on VC++through access to information is widely used for today s audio encryption algorithm to choose, and the three kinds of algorithms are compared, and its performance to find out one encryption)

基于LSB的信息隐藏技术——MFC——编译已经通过运行正常(LSB-based Information Hiding- MFC- has been compiled by running the normal)

凯撒密码作为一种最为古老的对称加密体制，在古罗马的时候都已经很流行，他的基本思想是：通过把字母移动一定的位数来实现加密和解密。例如，如果密匙是把明文字母的位数向后移动三位，那么明文字母B就变成了密文的E，依次类推，X将变成A，Y变成B，Z变成C，由此可见，位数就是凯撒密码加密和解密的密钥。个人原创。(Caesar password as one of the most ancient symmetric encryption system in ancient Rome have been very popular, his basic idea is: by the letters move a certain number of bits to achieve encryption and decryption. For example, if the key is the number of bits of plaintext letters backward move three, the plaintext letter B into a ciphertext E, and so on, X will become Y-become a B,, and Z becomes C Thus, the median is the Caesar cipher encryption and decryption keys.
