As far as I know, there isn't a commonly-deployed standard (outside
HTTPS) for this type of encrypted communication, but it's fairly
straightforward to implement encryption in Javascript, and use that to
exchange information between the client and server once the page has
been loaded.

Take a look at this page:


for a simple encryption algorithm, there's also a link on that page to
an implementation of AES, which should provide better security if
required. Whichever implementation you go for, the actual data can be
exchanged with XMLHttpRequest or IFRAME techniques as usual, see
http://www.ajaxian.com for more info on that.

Most browsers support Javascript, but you'd need some sort of fallback
for anyone who has disabled it - mobile/cell phone browsers usually
don't implement Javascript, for example.
