A C/C++ library for encription?
 

Hellpo, all!
I write on C/C++ for long time and i was wondering how to write a a program that uses some encriptions for a network connection.
I couldn't find anything in Google. I need some library for encription or some other way to do that.There is a section in Linux kernel configuration for supporting some encription methods. May be i have to call a function of the kernel and it will make this encription for me?
Please help. This question is not part of ANSI C,Gnu C/C++, GCC tutorials.

Thanks in advance if anybody help me. I am very appreciated for any help.

google for encryption library
cryptlib encryption library
google for cryptolib
cryptolib

The last name sounds familiar to me, although I seem to remember that is a bunch or source codes in C (and not C++)

Thanks a lot!
