Tool to encrypt local Python source code with AES-256, and dynamically 
load and run it, and bring it into the Lockdown namespace.
Uses HMAC for integrity check, AES-256 in counter mode for encryption.

THIS HAS NOT BEEN AUDITED FOR SECURITY HOLES.
USE AT OWN RISK. I'M NOT RESPONSIBLE FOR YOUR FAILURE TO HEED THAT WARNING.

Example usage::

        #!/bin/bash
        lockdown lockedfiles.vault secret/creds.py secret/my_funcs.py
        # Enter and repeat password.
        # Now would be a good time to delete the files you locked, 
        # but make sure not to lose that vault file.

In Python::

        #!/usr/bin/env python
        from lockdown import Lockdown
        locker = Lockdown('lockedfiles.vault')
        # Enter password.
        locker.unlock()

        # Login with encrypted credentials. Python files aren't there!
        # Note: It collapsed the path.
        # (so it's locker.creds, not locker.secret.creds)
        some_login(locker.creds.USERNAME, locker.creds.PASSWORD)

        # Call a function. 
        # NOTE: These can't import vaulted files within functions. 
        # Files are lost after unlocking!
        locker.my_funcs.scoobydoo()
        
        # To leave files out, do this instead:
        locker.unlock(delete=False)

You can see the potential uses, for example locking up a file with secret keys
and credentials with a master password, or disabling functionality of a script
and not exposing the source unless the password is available.
