在ASPX+MSSQL里看到这个加密，琢磨了几天还是不知道算法
这俩24位，BASE64的，但是我解出来是乱码
蛋都要碎了

乱码是一些无关紧要的说明
哪位告诉我一下加密方式或者帮我解一下算法，我蛋都要碎了。。 --------------------编程问答-------------------- 这可能是编码问题吧，把gb2312换成utf-8 --------------------编程问答--------------------

在线MD5 没有破解出来，估计不是常用明文加密。
我看代码
string[] userlogin = userBLL.UserLogins(name.Value.Trim(), password.Value.Trim());
这里就是加密吧，如果有数据库，跟踪一下，看看数据库里面是不是存有32位长MD5码？
你可以看看数据里面是不是这种规律？
如果有，替换成123的密文试试吧。
202cb962ac59075b964b07152d234b70 --我测试的123 字符符串
--------------------编程问答--------------------
那么，您的这个MD5怎么转换成24位的啊，我用BASE64弄出来老长了。
说起来，这个数据库也很奇怪，新添加的数据在表里10分钟之后就查不到了，里面只显示一条很老的 --------------------编程问答--------------------

加密方式是MD5 --------------------编程问答-------------------- /// <summary>

{
System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create();
byte[] bytes = new byte[16];
System.Text.ASCIIEncoding asc = new System.Text.ASCIIEncoding();
if (Old == true)
{
bytes = md5.ComputeHash(asc.GetBytes(Str));
}
else
{
bytes = md5.ComputeHash(asc.GetBytes(Str + PassExt));
}
return Convert.ToBase64String(bytes);
}
/// <summary>

/// <returns>添加密码后缀字符串后的密文</returns>
public string SHA1(string Str)

}
终于找到加密方式了，果然很蛋疼……
补充：.NET技术 , ASP.NET
