如何使用加密的用户名和密码登录用户 [英] how to login in user with encrypted username and password

问题描述

我创建了一个表单来在我的应用程序中登录我的用户，它的工作很简单，但我必须访问多个用户，这是我使用表单来创建表单来创建用户名和员工的密码。我正在使用以下代码来加密用户名和密码。

  string  passwordForEncryption =   sA23（^ A1& *％1）01Ax）@！21！@＃$％^& *（）7984651; 
  string  encryptedpassword = StringCipher.Encrypt（ddlRollNo.Text，passwordForEncryption）; 
  string  encryptedUserName = StringCipher.Encrypt（txtPassword.Text，passwordForEncryption）; 
 CTP.HRMS.Business.UserLogin ulogin =  new  Business.UserLogin（）; 
 ulogin.Role_Id = SafeConvert.ToByte（ddlRole.SelectedValue）; 
 ulogin.Employee_Id = encryptedUserName; 
 ulogin.Password = encryptedpassword; 
 

当用户登录时我使用以下代码

  string  passwordForEncryption =   sA23（^ A1& * ％1！）01Ax）@ 21 @＃$％^&安培; *（）7984651\" ; 
 
  string  encryptedpassword = StringCipher.Encrypt（txtPWD.Text，passwordForEncryption）; 
  string  encryptedUserName = StringCipher.Encrypt（txtUserName.Text，passwordForEncryption）; 
 
实体实体= 新实体（）; 
 CTP.HRMS.WebApp.EF.UserLogin login = entities.UserLogins.FirstOrDefault（x => x.Employee_Id == encryptedUserName&& x.Password == encryptedpassword）; 
 
  //   var login =（from u in entities.UserLogins  
  //  在实体中加入ee。u.Id上的雇员等于ee.Id  
 
  //  其中u.Password == encryptedpassword  
  //  && u.UserName == encryptedUserName  
  / /  选择新 
  //   { 
  //   FormalName = u.FormalName， 
  //   gisuyag = ee.Address  
  //  }）。FirstOrDefault（）;  
 
  if （login！=  null ）
 {
 MyUser.UserName = txtUserName.Text; 
 MyUser.Role_Id = login.Role_Id; 
  //   MyUser.FormalName = login.FormalName; //创建包含用于显示目的的完整登录用户名的fuield  
 FormsAuthentication.RedirectFromLoginPage（login.Id.ToString（）， true ）; 
} 
 
  else  
 {
 
  //  如果数据读取器不包含任何行，则表示用户名或密码为 
 
  //  不正确 
 
 txtUserName.Text =   ; 
 
 txtPWD.Text =  ; 
 
 Label3.Text =  用户名/密码不正确; 
} 
}

我怎么能这样做

加密信息可以是解密。您应该使用简单安全密码验证说明 [ ^ ]。

i have created a form to login my user in my application,its work fine for simple set up,but i have to access to multiple user that is way i am using a form to create a form to make a user name and password for the employee. i am using following code to encrypt user name and password.

string passwordForEncryption = "sA23(^A1&*%1)01Ax)@!21!@#$%^&*()7984651";
               string encryptedpassword = StringCipher.Encrypt(ddlRollNo.Text, passwordForEncryption);
               string encryptedUserName = StringCipher.Encrypt(txtPassword.Text, passwordForEncryption);
               CTP.HRMS.Business.UserLogin ulogin = new Business.UserLogin();
               ulogin.Role_Id = SafeConvert.ToByte(ddlRole.SelectedValue);
               ulogin.Employee_Id = encryptedUserName;
               ulogin.Password = encryptedpassword;

and when user login i am using following code

    string passwordForEncryption = "sA23(^A1&*%1)01Ax)@!21!@#$%^&*()7984651";

    string encryptedpassword = StringCipher.Encrypt(txtPWD.Text, passwordForEncryption);
    string encryptedUserName = StringCipher.Encrypt(txtUserName.Text, passwordForEncryption);

    Entities entities = new Entities();
    CTP.HRMS.WebApp.EF.UserLogin login = entities.UserLogins.FirstOrDefault(x =>x.Employee_Id==encryptedUserName && x.Password == encryptedpassword);

    //var login = (from u in entities.UserLogins
    //              join ee in entities.Employees on u.Id equals ee.Id

    //              where u.Password == encryptedpassword
    //                    && u.UserName == encryptedUserName
    //              select new
    //              {
    //                  FormalName = u.FormalName,
    //                  gisuyag = ee.Address
    //              }).FirstOrDefault();

    if (login != null)
    {
        MyUser.UserName = txtUserName.Text;
        MyUser.Role_Id = login.Role_Id;
      //  MyUser.FormalName = login.FormalName; //Create A fuield that contains full Name of logged in user for diaplay purpose
        FormsAuthentication.RedirectFromLoginPage(login.Id.ToString(), true);
    }

    else
    {

        //if data reader doesn’t contains any row, it means user name or password is

        //incorrect

        txtUserName.Text = "";

        txtPWD.Text = "";

        Label3.Text = "User Name/Password not correct";
    }
}

how i can i do this

Encrypted information can be decrypted. You should use hashing as described in Secure Password Authentication Explained Simply[^].
