lockdown 0.4.1

An un-audited security tool to encrypt Python code.

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.
