The purpose of this project is to easily exchange messages via binary protocol using an encrypted communication channel in the realtime.

Server supports users registration, authentication and authorization. Server is just a secured proxy, so the users behind the NAT (network address translation) can easily communicate with each other. Connection between user and server is end-to-end encrypted and client can verify server's identity via digital signature.

TODO

• Add messages queues for users to store messages in them while users are offline to allow them fetch messages later

Dependencies

Server is written entirely in Go. The following libraries are used:

• Sodium,
• Mongo-driver.

The project is currently in Beta

Desktop Linux client
Android client

Firstly, the LibSodium library and pkg-config are needed to be installed, example for Arch/Manjaro:

sudo pacman -S libsodium pkgconf

Secondly, the project dependencies are needed to be installed, and then, the actual build can be performed:

# should be executed from the repository's root directory
(cd src; go get)
(cd src/crypto; go test) # run crypto tests
go build -C src -o "$(pwd)/build/ExchatgeServer" ExchatgeServer
