采用md5方法对用户密码进行加密:

前台主要代码： <div>

    <ul >
    <li> 密        码:<asp:TextBox ID="txt_pwd" runat="server" Width="300px"></asp:TextBox></li>
    <li>加密结果:<asp:TextBox ID="txt_result" runat="server" Width="300px"></asp:TextBox></li>
    <li>
    <asp:Button ID="btn_encrypt" runat="server" Text="md5加密"
            onclick="btn_encrypt_Click" />
    </li>
    </ul>

    </div>

后台主要代码：

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Text;
using System.Security.Cryptography;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}

    protected void btn_encrypt_Click(object sender, EventArgs e)
    {
        txt_result.Text = md5Encrypt(txt_pwd.Text.Trim());
    }
    private string md5Encrypt(string sourceString)
    {
        UnicodeEncoding byteConverter = new UnicodeEncoding();
        byte[] byteArray = byteConverter.GetBytes(sourceString);//将原字符串转换为字节数组
        MD5 myMD5 = new MD5CryptoServiceProvider();
        byte[] output = myMD5.ComputeHash(byteArray);
        return Convert.ToBase64String(output);

}
}
