c#加密 asp解密

[try13698903461]

我在C#中加密一段代码，将之传给asp页面，由其来解密。请帮忙弄一个简单的加解密函数。

回jerrylyj ，我是C#加密，asp解密，是asp，不是asp.net。能否给出一个完整的代码？

[try13698903461]

顶上去，求高手帮助，谢谢

[try13698903461]

跪求高人帮忙，老板等着要

[try13698903461]

[a82344626]

自己知算法就可以解啦

[DiscussQuestions]

声明变量用dim name as string ,dim pwd as string ！
构造方法用New,
自己改一下1楼的代码就可以了

[jerrylyj]

asp的代码我看着晕，你自己用过应该可以改改

[try13698903461]

asp其实我不会，所以才发这个帖子的。求高人将代码贴出来

[try13698903461]

没有高手来指教下吗

[wl_bdqn]

protected String astrEncryptTable = "~@&)#?*/,_";
protected String Public__EncryptString(String s) //---加密字符串
{

s.Trim();
int i,j;
String DestStr="";
char[] sTemp;
sTemp = new char[s.Length+1];
for (int k = 0; k < s.Length; k++)
{
char tem;
tem = System.Convert.ToChar(s.Substring(k, 1));
sTemp[k] = tem;
}
String h, p;
for(i=0;i<s.Length;i++)
{
h = System.Convert.ToString(sTemp[i] ^ sTemp[i + 1] ^ 0xB8).Trim();
if(h.Length==1)h="00"+h;
if(h.Length==2)h="0"+h;
p="";
for(j=0;j<3;j++)
{
p=p+astrEncryptTable.Substring(System.Convert.ToInt32(h.Substring(j,1)),1);
}
DestStr=DestStr+p;
}
return DestStr;
}




protected String Public__UnEncryptString(String s) //---解密字符串
{
int i,j;
String DestStr = "", sTemp = "";
char [] ss;
ss=new char[1000];
for(i=0;i<s.Length;i++)
{
j = astrEncryptTable.IndexOf(s.Substring(i, 1)) ;
sTemp=sTemp+j.ToString().Trim();
}
j=0;
for(i=0;i<sTemp.Length;i+=3)
ss[j++] = System.Convert.ToChar(System.Convert.ToInt32(sTemp.Substring(i, 3)));
for (i = j; i > 0; i--)
{
ss[i - 1] = (char)(ss[i] ^ ss[i - 1] ^ 0xB8);
}
for (i = 0; i < s.Length; i++)
{
DestStr = DestStr + ss[i].ToString();
}
return DestStr;
}





以上是自己写的一个加密接迷方法 通过测试,
你把解蜜改成asp吧 就是vbscript

[try13698903461]

回楼上的，大哥，我不会ASP呀，

[try13698903461]

不会VB，没法改啊。要有现成的例子就好了。越简单的越好
