This is a C++ implementation of the concept of Neural Cryptography, which is a communication of two tree parity machines for agreement on a common key over a public channel. This exchanged public key is utilized to encrypt a sensitive message to be transmitted over an insecure channel using Rijndael cipher. This is a new potential source for public key cryptography schemes which are not based on number theoretic functions, and have small time and memory complexities. This is a proof-of-concept demo of how such a neural key exchange protocol in conjugation with AES encryption can be implemented in C++, which could be further extended in higher-level applications. Both CLI and GUI implementations of the software were created using Visual C++ (.NET framework).
