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.
#!/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.
#!/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.
