                                 DOCUMENTATION

________________________________________________________________________________

Lock - Talk is a console messenger based on TCP sockets and the TLS protocol for 

encrypting messages. 

There is no need to transfer certificates to each other; 

the client and server will generate them and do it for you. 

All you have to do is indicate the information in the certificates, 

wait and start communicating :)

-------------------------------------------------------------------------------

The init.py files are only needed at the very beginning to transfer certificates 

to each other. Then the client and server set a shared key and encrypt messages 

based on the Diffie-Hellman algorithm. The dialogue will continue until the 

client or server disconnects using the command ctrl+C.

Also, the init.py files create a key and certificate using the openssl library.

-------------------------------------------------------------------------------

                                    LAUNCH

-------------------------------------------------------------------------------

// Server lauch

// You need to specify an argument: through which port the server will 

// communicate with the client. If you do not specify it, you will 

// be prompted for a port automatically upon startup.

python3 server.py 8080

// or

python3 server.py

// Then he will ask you for information to obtain a license. Enter as you wish.

// You will then be presented with a blank line where you can enter something, 

// but it will not respond. This is the client's expectation.

// -----------------------------

// Client connection

// When running, you need to specify the arguments: Host and port. 

//If you do not specify them, the program will request them from you automatically.

python3 client.py

// or

python3 client.py 192.168.1.101 8080

// Then he will ask you for information to obtain a license. Enter as you wish.

// Now they will exchange certificates, connect to each other and you can 

//start your hidden communication.

                                     TO-DO

________________________________________________________________________________

1. In the plan: add to the next version of Lock-Talk an indication of the port 

   for exchanging certificates. Add changes to documentation. [X] 

   | Looking forward to this in future versions |
