asp版密码进行md5加密

Posted 2023-05-15

asp版的md5已经有了，测试也ok，怎么对密码进行md5加密，并且把加密过的密码进行保存

还需要个md5.asp
md5(需加密的字符)
MD5.ASP文件源程序

我用的就是这个程序，而且已经测试过了，ok；但是我最终的目的是对注册信息中的密码加密并保存，这个可难道我了，请教啊

追答

任何字段都可以加密，看下源程序吧，你提交的字段是否有问题

追问

没有问题，代码如下
...

" or upass="&" or pass="|" then
response.write "" & "alert('高高的');" & "history.back()" & ""
response.end
md5(password);
end if
next

参考技术A password=md5(password);
这句改下 参考技术B 呵呵，不知道现在解决了吗，其实楼上的是正解。来自：求助得到的回答 参考技术B 直接
md5(需加密的字符)追问

直接md5（“password”）；这样就ok了吗

追答

md5（password）
你的md5加密是单独的一个asp文件的话
应该在最上面加上

追问

不行，没有用，你玩过这个的话，不如我发文件给你，你帮我改下，然后发回来怎么样？

追答

有什么提示吗？加密不成功？还是其他的

追问

什么提示也没有，我看了数据库里面还是没有加密的字符

追答

不加密能存到数据库中吗
