Hi I've been using the code below to authenticate a user in the
database in my ASP.Net app but now I've built another Windows Forms
based application. I'm trying to use the below code but I guess there
is no equivalent to the
FormsAuthentication.HashPasswordForStoringInConfigFile function. Does
anyone know what I can use instead?

public bool VerifyPassword(string suppliedUsername,
                           string suppliedPassword)
       {
           bool passwordMatch = false;
           // Get the salt and pwd from the database based on the user
name.
           Helper helper = new Helper();
           string _connectionString = helper.GetConnection(_server);
           SqlConnection conn = new SqlConnection(_connectionString);
           SqlCommand cmd = new SqlCommand("LookupUser", conn);
           cmd.CommandType = CommandType.StoredProcedure;

           SqlParameter sqlParam = cmd.Parameters.Add("@username",
SqlDbType.VarChar, 255);
           sqlParam.Value = suppliedUsername;
           try
           {
               conn.Open();
               SqlDataReader reader = cmd.ExecuteReader();
               reader.Read(); // Advance to the one and only row
               // Return output parameters from returned data stream
               string dbPasswordHash = reader.GetString(0);
               string salt = reader.GetString(1);
               reader.Close();
               // Now take the salt and the password entered by the
user
               // and concatenate them together.
               string passwordAndSalt =
String.Concat(suppliedPassword, salt);
               // Now hash them
               string hashedPasswordAndSalt =
FormsAuthentication.HashPasswordForStoringInConfigFile(passwordAndSalt,
"SHA1");
               // Now verify them.
               passwordMatch =
hashedPasswordAndSalt.Equals(dbPasswordHash);
           }
           catch (Exception ex)
           {
               throw new Exception("Execption verifying password. " +
ex.Message);
           }
           finally
           {
               conn.Close();
           }
           return passwordMatch;
       }
