You're *protecting* the data, not *obscuring* the data. So, if
someone takes your hard drive, you know there's data on the hard
drive, but can't read it because it's *protected*. You didn't *hide*
the data, you *protected* the data through encryption.
The OP wanted to *obscure* (or *hide*) the data by changing the format
of the script. Running 'strings' may yield vital information
contained in the script turned binary. So, just changing the format
of the script to *hide* the code is a weak way to *protect* the code.
It's a subtle, but important, difference.
