The code you provided appears to be an implementation of the Diffie-Hellman key exchange protocol between a client and a server. This protocol allows two parties to establish a shared secret key over an insecure channel.
- The client establishes a connection to the server.
- It sends the values of p, generator, and A (calculated as pow(generator,a) % p) to the server.
- It receives the server's public key (serverB) and calculates the shared secret key (kab).
- The client prints the private key (a), the server's public key (serverB), and the shared secret key (kab).
- The client closes the connection.
- The server listens for incoming connections on port 8088.
- It accepts the client's connection.
- The server receives the values of p, generator, and A from the client.
- The server calculates its own public key (B) as pow(c_generator, server_private) % c_P and sends it back to the client.
- The server calculates the shared secret key (Kab) using the client's public key (c_Public) and its private key (server_private).
- The server prints its private key (server_private) and the shared secret key (Kab).
- The server closes the connection.
