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)

Rijndael algorithm修正了CBC下BUG的版本(有源代码）工作在：D5。作者：Sergey Kirichenko。--Rijndael algorithm that has revised BUG version under CBC(with source code).It works in D5. author:Sergey Kirichenko。

vc++编写的eky算法源码。 1、 用户确认eKey被锁定（使用“eKey测试”工具测试，显示错误代码为－9，则表示eKey被锁定）。-vc eky prepared by the algorithm source code. 1, the user mounts lock ( "CPU test" tests show that error code to-9, then the MPC lock).

汇编程序写的Hash校检程序，分享源码，支持SHA1和MD5两种，支持拉拽，支持剪切板的复制和比对，有进行条，自动计算耗时 （使用了不太精确的计时器），速度还是可以的，大概就这样。 

加密算法，java上的加密算法，对大家应该用帮助的一个加密算法。-encryption algorithm, java on the encryption algorithm, we should be used to help an encryption algorithm.
