Web Cipher is a client-side, cryptographically secure document JavaScript encryption technology. It allows even an inexperienced web author to establish virtually uncrackable safety measures on confidential data. Web Cipher is also fast, substantially overcoming the problem of speed in browser-based cryptology. It averages almost 15K per second in real-world tests on an iMac 333 MHz computer, much faster than similar utilities.
