Additions:
A note of efficiency : the kwypt_string method basically double-encrypts a string twice using the rc4 method. This is highly inefficient (effectively tripling string length). But it does add a little more security for public data against brute-force trolling attacks. For basic rc4 encryption, there are encrypt and decrypt methods available. (See [[http://klenwell.googlecode.com/svn/trunk/JS/kwyption/kwyption.core.js kwyption.core.js]] and the [[http://klenwell.googlecode.com/svn/trunk/JS/kwyption/rick4.js Rick 4 class]].)
