是用的美国标准的DES加密算法用C++编写的可以完成以内的字符垢加密...

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）-a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1)

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).
