CryptoManiac uses str2hex(string) as well as Rot 13, two very simple yet effective ways to scramble text. It can also grab remote source to be loaded in your text editor. This isnt a highly secure method of hiding your source code or script for the reason that; the browser needs to parse the data in order to understand it. Therefore if the browser can read it, regardless of the format, it would be insecure. But what Crypto Maniac can do is make it an annoyance to peek at your code. It also grabs source code from the web.
