I am making an AIR project. In that the AIR application sends a request to a PHP script. The script returns an encrypted file. Then the Application decrypts it. How to do this?  
(I **don’t want** the process **to send the file unencrypted and the AIR to encrypt it** because I want the file link encrypted.)  
Also is there anyway like modifying the header of the file or something like that?
