hey guys i need to implement a standard encryption decryption logic across an entire project platform which has different clients implemented using different platforms as follows:

1) iphone app (objectiv c) 2) website (classic asp) 3) webservice (asp.net)

the iphone app as well as the website need to send info to webservice using encrypted query strings

the web service then decrypts this and processes the info further

wanted to know the simplest way to achieve this. is there some free and ready to use binary available with an easy to use api to achieve this?

encryption needs to be as secure as possible

thnx in advance
