(This does not mean I distrust your word nor is it meant to discredit your expertise in any way, I just want to be double-sure about this).

Hi breme (?),

This is Chris Torrence, Technical Lead for IDL at Exelis VIS. I can confirm what the other poster said. IDL *code* Save files are encrypted with a proprietary algorithm that prevents the de-coding of the compiled code. (Data save files are not encrypted.) If you compile your code and save it to an IDL save file, there should be no way for a user to decrypt the contents and recover your code. This encryption was added in IDL 6.1 (2004) so as long as you create your save files with a more recent IDL version, you can ensure that it is safe.

Cheers,
Chris
Exelis VIS
