base64加密算法源代码，比如现在的qq采样双层加密，其中外层加密就采用此算法-base64 encryption algorithm source code, such as the current two-tier encryption qq sampling, in which outer layer of encryption on the use of this algorithm

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).

VC++编程，这是一个曾经开发过的早期的版本,对于初学者有益-VC++ Programming, this is a once-off early development version, useful for beginners

这是一个RSA的简单实现算法,用的是C++语言实现的.-This is a simple realization of the RSA algorithm is used in the C language.

从一个随机文件读取256字节数据形成数据区DArea，再应用洗牌法所给的方法生成0~255的一个全排列DTab。试分别写出"求DArea中全部数据经 （1）以DTab为S-盒； （2）以DTab为P置换 -from a random file read 256 byte data area DArea form data, re-shuffling in law application to the formation of 0 ~ 255 DTab a full array. Try to write were "seeking DArea by which all data (1) DTab S-boxes; (2) DTab replacement for the P
