At previous employers I worked in Oracle and we used the "Wrap" function to obfuscate (love that word) the code. "Wrap"ped code was only readable by the Oracle runtime engine, I have not seen a hack of it, but there might be. Anyway ... we wrapped or code because we were in a very competitive "new-idea" market. Letting our competitors see how we accomplished what we did would place us at a dis-advantage. Don't now if that was really true, but that was our story.
