obfuscation - How can I obfuscate (protect) JavaScript? -

-

i want make javascript application that's not open source, , wish learn how can obfuscate js code? possible?

obfuscation:

try yui compressor. it's popular tool, built, enhanced , maintained yahoo ui team.

you may use:

private string data:

keeping string values private different concern, , obfuscation won't of benefit. of course, packaging source garbled, minified mess, have light version of security through obscurity. of time, it's user viewing source, , string values on client intended use, sort of private string value isn't necessary.

if had value never wanted user see, have couple of options. first, kind of encryption, decrypted @ page load. 1 of secure options, lot of work may unnecessary. base64 encode string values, , easier.. wanted string values easily decode them. encryption way prevent accessing data, , people find more security need.

sidenote:

obfuscation in javascript has been known cause bugs. obfuscators getting little better it, many outfits decide see enough benefit minifying , gzipping, , added savings of obfuscation isn't worth trouble. if you're trying protect source, maybe you'll decide it's worth while, make code harder read. jsmin alternative.
