So, in a case where the passwords cannot be cracked, you need to calculate it yourself:

You just use the same procedure. Make a series of guesses, hash them, and hunt for your answer. If your list of guesses does eventually hit the right value, you'll of course find it here. So, you can see the password P@sw0rd999 with 5c2c....
It's very simple, so let's give it a try in Python.
In the Terminal window, we'll enter the python command. Next we'll import the hashlib library:

Thus, you can see the line that does the encoding. We put in the password, encode utf-16le, which is the Unicode; then, we hash it with MD4 and express it as hexdigest.
That's number for P@sw0rd. Now, if we try to get to the Ringo user, we need to have a list of two hashes to try, which will need to have some values that eventually reach the right value:

If we are just counting up sequentially using 997, 998, and 999, we'll get that 5c2c... value that we are looking for.
