signal-cli is a command line interface for the Signal messenger. It supports registering, verifying, sending and receiving messages. signal-cli uses a patched libsignal-service-java, extracted from the Signal-Android source code. For registering you need a phone number where you can receive SMS or incoming calls. signal-cli is primarily intended to be used on servers to notify admins of important events. For this use-case, it has a daemon mode with D-BUS interface (man page) and JSON-RPC interface (documentation). For the JSON-RPC interface, there's also a simple example client, written in Rust.

Features

  • Install system-wide on Linux
  • You can register Signal using a landline number
  • Build a native binary with GraalVM
  • This project uses Gradle for building and maintaining dependencies
  • The Signal protocol expects that incoming messages are regularly received (using daemon or receive command)
  • The password and cryptographic keys are created when registering
