# pchat

pchat is a peer to peer private chat using two key pairs per user: one for the

secure channel (TLS 1.3) and one for the messages content in order to achieve

forward secrecy.

Messages are never stored. Both peers need to be online for the communication

to be possible. Group chat is not implemented. Only short text messages can be

sent.

This is a pet project to learn cryptography, don't use it to communicate real

secrets.

## Build:

    go build

## Generating keys:

To test pchat, generate keys for two users

    ./pchat -i marcelo

    ./pchat -i sonia

## Import contacts:

    mkdir ~/.pchat/contacts/marcelo

    cp ~/.pchat/marcelo.crt ~/.pchat/contacts/marcelo/crt

    cp ~/.pchat/marcelo.pub ~/.pchat/contacts/marcelo/pub

    echo "https://localhost:3008" ~/.pchat/contacts/marcelo/endpoint

    mkdir ~/.pchat/contacts/sonia

    cp ~/.pchat/sonia.crt ~/.pchat/contacts/sonia/crt

    cp ~/.pchat/sonia.pub ~/.pchat/contacts/sonia/pub

    echo "https://localhost:3009" ~/.pchat/contacts/sonia/endpoint

## Chat:

    ./pchat -i marcelo -contact sonia -port 3008

    ./pchat -i sonia -contact marcelo -port 3009
