How to submit this file challenge crack to the server
-----------------------------------------------------

Your target for this challenge is the NTLM password for user 'test2'.
We don't care about the others.  To submit the plaintext for test2,
craft the usual PGP signed/encrypted email, but instead of sending the
individual plaintext, the challenge submission should contain:

filename plaintext

Notice the space (' '), and there is no colon (':').

So for this challenge, if user test2's password was "defcon", you would
submit:

sam-medium.zip defcon

You can mix this in with a submission of password cracks.  Unlike with
password crack submissions, you do not need to send us all your
challenge file cracks every time you crack a new challenge (although
there is no problem doing so, either).
