WIFI-Direct Android

[Mutasim dafalla]

Hello every one ..
I'm looking for an android application which will implement the wifi direct module.
The app will be required to send encrypted data over wifi connection. The data will be encrypted using the RSA algorithm.
The app should show the peers available for wifi connection. User should be able to choose the peer it want to connect.
The app should then ask from the receiver for the RSA key. It should then encrypt the data and send it over the wifi connection. 
The app should also have a functionality of being a receiver. On getting a data receive request it should generate its RSA keys i.e the public key and the private key. And then send it to the connection asking for keys. On receiving the encrypted data it should prompt the user if it wants to decrypt the data or not. 
If the user selects to decrypt it decrypts using its private key , To sum up.... An app is required which should act both as a sender and a receiver..
if any one has please contact me  mutasi...@yahoo.com
