How to create a asp.net membership provider hashed password manually?

Question

I\'m using a website as a frontend and all users are authenticated with the standard ASP.NET Membership-Provider. Passwords are saved \"hashed\" within a SQL-Database.

You can absolutely use System.Web.Security within a console or winforms app.

Here's a simple console application:

static void Main(string[] args)
{
    MembershipProvider provider = Membership.Provider;

    MembershipUser myUser = provider.GetUser("myUser", false);

    if( myUser != null ) provider.DeleteUser("myUser", true);

    MembershipCreateStatus status;

    myUser = provider.CreateUser("myUser", "password", "user@example.com", null, null, true, null, out status);

    if (status != MembershipCreateStatus.Success)
    {
        Console.WriteLine("Could not create user.  Reason: " + status.ToString());
        Console.ReadLine();
        return;
    }

    Console.WriteLine("Authenticating with \"password\": " + provider.ValidateUser("myUser", "password").ToString());

    string newPassword = myUser.ResetPassword();

    Console.WriteLine("Authenticating with \"password\": " + provider.ValidateUser("myUser", "password").ToString());
    Console.WriteLine("Authenticating with new password: " + provider.ValidateUser("myUser", newPassword).ToString());

    Console.ReadLine();
}

And the app.config:
