encode the query string

[omerbutt]

hi there can any one tell me that if there is a way to encode a query string that i am sending through ajax i kow it does not show the query string in the address bar but Browsers like mozilla have the addons like firebug that can show the whole string that is being sent via ajax i know the encodeURI but it is not that much secure i want to use one like "base65_encode( )" or "md5()" in PHP.....or there is a way to use one of these in javascript/ajax ...........
regards,
omer aslam

Any string sent via Ajax can be viewed by the client. He did make the request in the first place, so why not?
