101-OpenSSL question..

[abce1234]

Hi expert guys,..   :)   I'm starting a class project which requires handling a packet after encryption it, and before transmi it to the IP layer. I want to to add a header and modify the current IP address of the packet.    The steps -- in summery -- are as follow:   ************************************************** 1- Packet encryption. (I have nothing to do with it) -------------------------------------- 2- My work:       Get a packet.       Add my own header information to it.       Modify the IP address.       Pass it to the next layer. -------------------------------------- 3- Send it to TCP/IP layer for transmit  (I have nothing to do with it too)   **************************************************      So I need your help to step me in the first step of this project, I need to know from where to start. I download the OpenSSL project, and I found 1500 files ,,!!!   So would you mind pointing me out to the files that I should start modifying and playing with.   Any information is valuable to me and appreciated  :)   Thanks alot.   Dave.
