Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.
If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md
Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.

| I was thinking of what it would take to have a function like: | |
| decrypt_if_input_valid(encrypted_data, input) | |
| this function checks if the input satisfies some criteria, and if it does it will decrypt the data. | |
| suppose our input is a list of numbers, and our criteria is "each number has to be at most 2 away from the number 378." writing this is fairly straightforward | |
| however, if we want to distribute this function, it is trivial for someone to decompile it and see what it's checking for. is it possible to use cryptography to hide our validation criteria so we can run our code on insecure systems? |
