In this day and age, the Internet is a dangerous place, full of crackers, viruses, trojans, popups, and spyware. System compromises are common now, and your precious source code may be in danger. To prevent this, it is always important to make sure your code has not been tampered with.

SCO, the Source COde authentication toolset, is designed to encode and decode your source code files, line by line, with your GPG key. If a single line is tampered with, you'll know about it, and be safe from those evil crackers!

SCO requires a working Python installation, gpg, and a gpg key. You must also have the gpg key on your keyring of any code you wish to decode.
