Which type of encryption algorithms android supports, and which would be better?
I am confused about to use of DES. Triple DES, RSA and AES algorithms, I think I couldn't get more idea about them, so I am not able to think which algo would be better.
My Task :
I am developing an application who sends an encrypted String to PHP server, and PHP server decrypt it, and sends response to my application.
Please explain which algo should be better on Android and PHP both, and why?
