C++Please!!

Build a file server from which a client can request files. Pick a programming language and investigate how to use its networking libraries. Conduct some research on network or socket programming in the language you choose. Build on the above so as to provide confidentiality of the files transmitted by the server to the client. Use a symmetric key crypto algorithm such as 3DES or AES in CBC mode. Generate a key on the server side. Export this key into a file. Using a secure/private channel, copy this file (key) to the client computer. Consult the crypto libraries for the C++ programming language. You can find crypto libs for C++. The goal is to learn how to use the crypto APIs for symmetric key encryption and decryption, key generation and for exporting the key so it can be shared between the client and the server.
