ASP 改良版MD5、SHA256多重加密类（二次及多次）

网学网ASP编辑为广大网友搜集整理了：asp 改良版MD5、SHA256多重加密类（二次及多次）绩等信息，祝愿广大网友取得需要的信息，参考学习。

目前可实现：MD5算法、SHA256算法、先MD5后SHA256、先SHA256后MD5、两次MD5、两次SHA256、前8位MD5算法后8位SHA256算法、前8位SHA256算法后8位MD5算法、取密码最后一个字符的AscW值与8的余数作为加密方案系数、16位MD5加密、32位MD5加密、8位SHA256加密、16位SHA256加密、24位SHA256加密、32位SHA256加密、40位SHA256加密、48位SHA256加密、56位SHA256加密、64位SHA256加密等算法，看过源码之后，更可以自定义更多加密组合及加密算法，跟暴力破解MD5算法说拜拜吧~~
