怎样用md5对数据库进行加密

Question

using System.Security.Cryptography;
using System.Text;
// 片断代码
string _password ;
string _encPassword_password = "abcdefg";UnicodeEncoding uEncode = new UnicodeEncoding(); // 也可以用 ASCIIEncodingbyte[] hashPassword = uEncode.GetBytes(_password);
MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();

_encPassword = Convert.ToBase64String(md5.ComputeHash(hashPassword));

Answer 1

函数:Function EncryptPassword(PassWordString As String,PassWordFormat As String)
       If PassWordFormat ="SHA1" Then
          EncryptPassword =FormsAuthentication.HashPasswordForStoringInConfigFile(PassWordString,"SHA1")
       ElseIf PassWordFormat ="MD5" Then
          EncryptPassword =FormsAuthentication.HashPasswordForStoringInConfigFile(PassWordString,"MD5")
       Else
          EncryptPassword =PassWordString  
       End If  
    End Function调用时:EncryptPassword(txtPassWord.text,"SHA1")

Answer 3

用MD5时用:EncryptPassword(txtPassWord.text,"MD5")

Answer 4

using System.Web.Security;
private void login_Click(object sender, System.EventArgs e)
 {
  epwd=FormsAuthentication.HashPasswordForStoringInConfigFile(pwd.Text, "SHA1");
  //epwd=FormsAuthentication.HashPasswordForStoringInConfigFile(pwd.Text, "MD5");
  Response.Write(epwd);
 }
