Hulu Encrypted PID/Smil Decoding?

[JonDough]

I looking for some php, python or perl code that decrypts the hulu pid/smil data directly and locally. I'm not referring to the caption data or the video streams themselves, but rather the pid/smil data that contains encrypted data of the video stream location(s). I also don't need anything that does network access to find the url of the pid/smil. I just need a script that takes local encrypted text input and decodes it to a local output.

The "get-flash video" script and some xbmc scripts had this sort of code, but they have legacy dependencies that are obsolete or unnecessary. Anyone have this or know how to break down the other scripts so that they have only this functionality and no needless dependencies?
