winsock end to end AES 256bit chat

Hello,

I'm looking to create a chat application that has no client server required.. just user to user only with AES 256bit encryption. I've read up on winsock and starting to understand the terms and syntax of it but still a bit confused on how I'm going to incorporate encryption methods... (I do have C++ knowledge but none in networking, and do wish to start getting into it). Is their a tutorial or source code examples of another project anyone knows?
Format I wish to use..

user enters in keyword (base64 32bytes).. user types IP:Port.. User types message.. And not looking to use any GUI.. just all in a DOS style.. also.. (user1)AES-256 --> base64 encryption --> sends --> base64 decoder --> displays message (user2)

This is just an academic project or a personal project for experimentation, right?

Try searching the Web for "C++ encryption library". Since only private key encryption is involved here, you are assuming that both parties have already exchanged keys over a secure channel.

Yes, this is personal. Just want to figure out how to build this and get more into network security.

And I'll check out some encryption libraries thanks. And correct

You can get your basic client/server "hello world" samples from this tutorial: Beej's Guide to Network Programming

for crypto libraries, I have used cryptopp a little bit, and found it to be quite powerful and relatively easy to use. it includes support for all common encryption algorithms, including DES, AES, Blowfish, etc.
