Cryptology, and all that jazz

One unresolved puzzle in my mind is public key encryption. I've heard this jargon for more than 10 years. I know it is an asynchronous encryption mechanism, but I never really know how it works. Luckily, today I find this web site that talks about it. Better yet, it is in Trad Chinese, with sample code. Oh Yes!!
