   1 # signal-cli
   2
   3 signal-cli is a commandline interface
   4 for [libsignal-service-java](https://github.com/WhisperSystems/libsignal-service-java). It supports registering,
   5 verifying, sending and receiving messages. To be able to link to an existing Signal-Android/signal-cli instance,
   6 signal-cli uses a [patched libsignal-service-java](https://github.com/AsamK/libsignal-service-java), because
   7 libsignal-service-java does not yet
   8 support [provisioning as a linked device](https://github.com/WhisperSystems/libsignal-service-java/pull/21). For
   9 registering you need a phone number where you can receive SMS or incoming calls.
  10
  11 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
  12 interface ([man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli-dbus.5.adoc)) and JSON-PRC interface ([documentation](https://github.com/AsamK/signal-cli/wiki/JSON-RPC-service)). For the JSON-RPC interface there's also a simple [example client](https://github.com/AsamK/signal-cli/tree/master/client), written in Rust.

  14 ## Installation
  15
  16 You can [build signal-cli](#building) yourself or use
  17 the [provided binary files](https://github.com/AsamK/signal-cli/releases/latest), which should work on Linux, macOS and
  18 Windows. There's also a [docker image and some Linux packages](https://github.com/AsamK/signal-cli/wiki/Binary-distributions) provided by the community.
  19
  20 System requirements:
  21
  22 - at least Java Runtime Environment (JRE) 17
  23 - native library: libsignal-client
  24
  25   The native libs are bundled for x86_64 Linux (with recent enough glibc), Windows and MacOS. For other
  26   systems/architectures
  27   see: [Provide native lib for libsignal](https://github.com/AsamK/signal-cli/wiki/Provide-native-lib-for-libsignal)
  28
  29 ### Install system-wide on Linux
  30
  31 See [latest version](https://github.com/AsamK/signal-cli/releases).
  32
  33 ```sh
  34 export VERSION=<latest version, format "x.y.z">
  35 wget https://github.com/AsamK/signal-cli/releases/download/v"${VERSION}"/signal-cli-"${VERSION}"-Linux.tar.gz
  36 sudo tar xf signal-cli-"${VERSION}"-Linux.tar.gz -C /opt
  37 sudo ln -sf /opt/signal-cli-"${VERSION}"/bin/signal-cli /usr/local/bin/
  38 ```
  39
  40 You can find further instructions on the Wiki:
  41
  42 - [Quickstart](https://github.com/AsamK/signal-cli/wiki/Quickstart)
  43 - [DBus Service](https://github.com/AsamK/signal-cli/wiki/DBus-service)
  44
  45 ## Usage
  46
  47 For a complete usage overview please read
  48 the [man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli.1.adoc) and
  49 the [wiki](https://github.com/AsamK/signal-cli/wiki).
  50
  51 Important: The ACCOUNT is your phone number in international format and must include the country calling code. Hence it
  52 should start with a "+" sign. (See [Wikipedia](https://en.wikipedia.org/wiki/List_of_country_calling_codes) for a list
  53 of all country codes.)
  54
  55 * Register a number (with SMS verification)
  56
  57         signal-cli -a ACCOUNT register
  58
  59   You can register Signal using a land line number. In this case you can skip SMS verification process and jump directly
  60   to the voice call verification by adding the `--voice` switch at the end of above register command.
  61
  62   Registering may require solving a CAPTCHA
  63   challenge: [Registration with captcha](https://github.com/AsamK/signal-cli/wiki/Registration-with-captcha)
  64
  65 * Verify the number using the code received via SMS or voice, optionally add `--pin PIN_CODE` if you've added a pin code
  66   to your account
  67
  68         signal-cli -a ACCOUNT verify CODE
  69
  70 * Send a message
  71
  72         signal-cli -a ACCOUNT send -m "This is a message" RECIPIENT
  73
  74 * Pipe the message content from another process.
  75
  76         uname -a | signal-cli -a ACCOUNT send --message-from-stdin RECIPIENT
  77
  78 * Receive messages
  79
  80         signal-cli -a ACCOUNT receive
  81
  82 **Hint**: The Signal protocol expects that incoming messages are regularly received (using `daemon` or `receive`
  83 command). This is required for the encryption to work efficiently and for getting updates to groups, expiration timer
  84 and other features.
  85
  86 ## Storage
  87
  88 The password and cryptographic keys are created when registering and stored in the current users home directory:
  89
  90         $XDG_DATA_HOME/signal-cli/data/
  91         $HOME/.local/share/signal-cli/data/
  92
  93 ## Building
  94
  95 This project uses [Gradle](http://gradle.org) for building and maintaining dependencies. If you have a recent gradle
  96 version installed, you can replace `./gradlew` with `gradle` in the following steps.
  97
  98 1. Checkout the source somewhere on your filesystem with
  99
 100         git clone https://github.com/AsamK/signal-cli.git
 101
 102 2. Execute Gradle:
 103
 104         ./gradlew build
 105
 106    2a. Create shell wrapper in *build/install/signal-cli/bin*:
 107
 108         ./gradlew installDist
 109
 110    2b. Create tar file in *build/distributions*:
 111
 112         ./gradlew distTar
 113
 114    2c. Create a fat tar file in *build/libs/signal-cli-fat*:
 115
 116         ./gradlew fatJar
 117
 118    2d. Compile and run signal-cli:
 119
 120         ./gradlew run --args="--help"
 121
 122 ### Building a native binary with GraalVM (EXPERIMENTAL)
 123
 124 It is possible to build a native binary with [GraalVM](https://www.graalvm.org). This is still experimental and will not
 125 work in all situations.
 126
 127 1. [Install GraalVM and setup the enviroment](https://www.graalvm.org/docs/getting-started/#install-graalvm)
 128 2. [Install prerequisites](https://www.graalvm.org/reference-manual/native-image/#prerequisites)
 129 3. Execute Gradle:
 130
 131         ./gradlew nativeCompile
 132
 133    The binary is available at *build/native/nativeCompile/signal-cli*
