JavaScript Obfuscator/Scrambler
Hi Experts,
I'm trying to find a solution that will obfuscate/scramble some piece of JavaScript code. The code I'd like to obfuscate is in a standalone js file. I know this isn't secure at all, as anyone with minimal knowledge can reverse it.
Nevertheless, I'd like - with your help - to cook something that'll waste a bit of their time when attempting to do so.
So far I'm familiar with the "escape" way of doing things, but would like something more ellaborate. Preferably something that uses a few rounds of obfuscation, let's say 6 rounds.
Each round would use the code from previous round, with a twist, so hopefully no automatic program can be written to do it and they'll have to do each round by hand.
Now, before you start jumping at me and say this isn't secure and better get something else doing, I know it isn't. I ain't looking for security here. Just to waste any wannabe hacker as much of his time as possible when he attempts to snoop over this piece of code.
Great creative minds of experts here have come up more than once with brilliant solutions for my previous problems. Hope you can help once more :)
Thank you.
Sincerely,
Catalin Ionescu

basicinstinct,
Thank you for your feedback and ideas. The resulting script should work both in IE and FF.
Please correct me if I am wrong, but from what I am able to tell, Microsoft's solution only works in IE and is only for JScript and VBScript, not JavaScript.
Onyx23,
Yes, that's a good start. Stunnix produces good results, but costs almost $300 :( Any idea of a freeware or low cost shareware that does about the same job?
For everybody else, please keep the ideas flowing.

Onyx23,
Thank you for the link.
It is pointing to the same program as the sharewareconnection.com link you've sent earlier.
The resulting code isn't too "obfuscated". Just look at the sample.

Actually, you could take the obfuscated code from Onyx and run it through Windows Script Encoder to make it even more obfuscated.
Of course, nothing can hide your javascript from someone who really wants to see it.
