hi, i have this code for example in my html or in a .js file and i want know if there is some way to encrypt or dificult the reading by humans ex: var a=1 if x==1 [ etc thanks for your help
Well there's no real way to actually 'encrypt' the javascript, but you can obfusicate it (making it difficult to read/edit). One of the most popular way to do it is to use a packer. http://dean.edwards.name/packer/ The dean edwards packer was one of the first ones to become heavily popularized. But like with some obfuscation methods, the same generator can often times decode them again. Here are some that may be better suited. Dojo ShrinkSafe : http://shrinksafe.dojotoolkit.org/ YUI Compressor : http://developer.yahoo.com/yui/compressor/ JSMin (Popular with Jquery) : http://www.crockford.com/javascript/jsmin.html Personally I prefer JSMin, but not everyone likes the command line approach. Since they don't provide true security so to speak (Even though they thwart off most people who don't have the knowledge to reverse it), they are handy for reducing the file size for a quicker loading site.
