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:
- iphone app (objectiv c)
- website (classic asp)
- webservice (asp.net)
- samsung bada app (c++)
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
edited: currently we use AES on the website and webservice front
thnx in advance
Luckily encryption algorithms are well defined by standards (at least the good ones), so you should be able to find inter operable implementations for the required platforms. You probably want to use AES for the encryption?
Any idea how you will distribute the keys?
