The legal way is to ask the person who encoded it for the source.

Definitely a learning experience where you learn to retain original source, and a record of the process which you used to transform the content from one form to another.

My rule of thinking is the following:

You created the original. You're not capable of replicating what you did?
From what you have, it is either possible to reverse engineer, versus not. If possible, it is next a question of whether it is worth your time to do this versus re-do your original efforts.
We all learn new techniques at doing stuff. If this script is less than a year (or some acceptable time frame) old (a) definitely applies. If the script is very old, then one would wonder if a more current way to do things would be applicable.
What about looking in to file recovery? Like Photorec or another file recovery mechanism where you apply it to a known source directory location where you know you once had the source and have a possibility of recovery some or all of that original source?
