JavaScript Shopping & Crypto Kickoff

Hi, all!

This is a fun project: imagine secure e-commerce which is entirely browser (client) based... No CGI to set up & debug; no expensive hosting fees; And costomers like it because it's responsive! ... That's where I'm heading.

Javascript is very responsive even on slow servers, because it doesn't use the server at all!

I've got the shopping cart written and the customer info page written. I'm working getting the customer data verified, and then the final posting part of the shopping cart.

As far a crypto goes, I've got RC4 (for session encryption) and arbitrary length modular math going. Something like base64 encoding/decoding works. I'm working on generating keys so I can speed test the modular exponentiation routine and find how long a key my arbitrary math functions will support in reasonable time... And how long would a customer wait for his/her browser to encrypt data? That's a good question.

I'll work on getting the pages I've completed posted this week or early next (ie before 12/20).

Also, if anyone can counsel me on patent issues which may affect this project, please let me know!

John
