I have to make a sample program, client-server, that has to transfer some data across a network, but I have to use C++ and it must use IPSec protocol (AH or ESP).

[j0nas]

IPSec is low-level stuff... normally carried out by a device driver in the IP stack. I don't know if it is even possible to implement IPSec from an application (through RAW sockets maybe).

Can't you let the operating system handle the IPSec for you?

[Adrian_Shadow]

I could tel OS handle IPSec for me. But I would need at least some documentation on socket() function in C, especially on [protocol] parameter (in particulary for values IPPROTO_AH and IPPROTO_ESP). If I use those values for creating a Socket, I still use a trnsport protocol or I must make one myself.
