I already encrypted password as 32bit character in client side, but the password encryption should be dynamic.

example:

1st time login

password: abcd => xcvb12ncn(encrypted password)

2nd time login

password abcd => dfghgfgh5(encrypted password)

You can use password salt as described:

Plz try ths for encryption...

C#

System.Web.Security.FormsAuthenticationTicket EncPass = new         FormsAuthenticationTicket(txtPass.Text.Trim(), false, 600);
System.Web.Security.FormsAuthenticationTicket EncUser = new FormsAuthenticationTicket(txtUser.Text.Trim(), false, 600);
            // returns encrypted string.
            string pass = FormsAuthentication.Encrypt(EncPass);
            string User = FormsAuthentication.Encrypt(EncUser);
            //Setting the Cookies value. 

            Response.Cookies["UName"].Value = User;
            Response.Cookies["PWD"].Value = pass;
            Response.Cookies["UName"].Expires = DateTime.Now.AddDays(30);
            Response.Cookies["PWD"].Expires = DateTime.Now.AddDays(30);

Solution 3

Login info is very sensitive which should be carefully handled. See my answer related to this one.

Remember, no encryption is secured.
