The actual correct answer is 1: for tempest: educate yourself before posting please, 2: search for the most commonly used encryption algorythms and run a few tests (you know, like a scientist). Never know, you might catch on to something.

You actually thought I was serious???

But you go ahead and help someone out who may be trying to hack someone else's code so maybe he can get access to something he shouldn't be...

encrypted its not best word for this. Js can't be encrypted.
I think you meant obfuscated.

Many cheaters/scammers (not to mention several worms) abuse things like jscript.encode, so in quite a few cases wanting to see what's underneath is entirely legitimate.

However, his question is too broad to answer here. It's like asking "how do you decode something that's been encoded". The answer, of course, is that it depends on how it's been encoded.

Its like somebody asking how they could remove a waterwork from an image.

No, it's not. This is something that is not quite as harmless as watermarks, and is used extremely often to hide shady stuff - actually including using stolen scripts and such.
