   1 # signal-cli
   2
   3 signal-cli is a commandline interface for [libsignal-service-java](https://github.com/WhisperSystems/libsignal-service-java). It supports registering, verifying, sending and receiving messages.
   4 To be able to link to an existing Signal-Android/signal-cli instance, signal-cli uses a [patched libsignal-service-java](https://github.com/AsamK/libsignal-service-java), because libsignal-service-java does not yet support [provisioning as a slave device](https://github.com/WhisperSystems/libsignal-service-java/pull/21).
   5 For registering you need a phone number where you can receive SMS or incoming calls.
   6 signal-cli is primarily intended to be used on servers to notify admins of important events. For this use-case, it has a dbus interface, that can be used to send messages from any programming language that has dbus bindings.

   8 ## Installation
   9
  10 You can [build signal-cli](#building) yourself, or use the [provided binary files](https://github.com/AsamK/signal-cli/releases/latest), which should work on Linux, macOS and Windows. For Arch Linux there is also a [package in AUR](https://aur.archlinux.org/packages/signal-cli/). You need to have at least JRE 7 installed, to run signal-cli.
  11
  12 ### Install system-wide on Linux
  13 See [latest version](https://github.com/AsamK/signal-cli/releases).
  14 ```sh
  15 export VERSION=<latest version, format "x.y.z">
  16 wget https://github.com/AsamK/signal-cli/releases/download/v"${VERSION}"/signal-cli-"${VERSION}".tar.gz
  17 sudo tar xf signal-cli-"${VERSION}".tar.gz -C /opt
  18 sudo ln -sf /opt/signal-cli-"${VERSION}"/bin/signal-cli /usr/local/bin/
  19 ```
  20 You can find further instructions on the Wiki:
  21 - [Install on Ubuntu](https://github.com/AsamK/signal-cli/wiki/HowToUbuntu)
  22 - [DBus Service](https://github.com/AsamK/signal-cli/wiki/DBus-service)

  24 ## Usage
  25
  26 Important: The USERNAME (your phone number) must include the country calling code, i.e. the number must start with a "+" sign. (See [Wikipedia](https://en.wikipedia.org/wiki/List_of_country_calling_codes) for a list of all country codes.
  27
  28 * Register a number (with SMS verification)
  29
  30         signal-cli -u USERNAME register
  31
  32   You can register Signal using a land line number. In this case you can skip SMS verification process and jump directly to the voice call verification by adding the --voice switch at the end of above register command.
  33
  34 * Verify the number using the code received via SMS or voice
  35
  36         signal-cli -u USERNAME verify CODE
  37
  38 * Send a message
  39
  40         signal-cli -u USERNAME send -m "This is a message" RECIPIENT
  41
  42 * Pipe the message content from another process.
  43
  44         uname -a | signal-cli -u USERNAME send RECIPIENT
  45
  46 * Receive messages
  47
  48         signal-cli -u USERNAME receive
  49
  50 For more information read the [man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli.1.adoc) and the [wiki](https://github.com/AsamK/signal-cli/wiki).
  51
  52 ## Storage
  53
  54 The password and cryptographic keys are created when registering and stored in the current users home directory:
  55
  56 `$XDG_DATA_HOME/signal-cli/data/` (`$HOME/.local/share/signal-cli/data/`)
  57
  58 For legacy users, the old config directories are used as a fallback:
  59
  60         $HOME/.config/signal/data/
  61
  62         $HOME/.config/textsecure/data/
  63
  64 ## Building
  65
  66 This project uses [Gradle](http://gradle.org) for building and maintaining
  67 dependencies. If you have a recent gradle version installed, you can replace `./gradlew` with `gradle` in the following steps.
  68
  69 1. Checkout the source somewhere on your filesystem with
  70
  71         git clone https://github.com/AsamK/signal-cli.git
  72
  73 2. Execute Gradle:
  74
  75         ./gradlew build
  76
  77 3. Create shell wrapper in *build/install/signal-cli/bin*:
  78
  79         ./gradlew installDist
  80
  81 4. Create tar file in *build/distributions*:
  82
  83         ./gradlew distTar
  84
  85 ## Troubleshooting
  86 If you use a version of the Oracle JRE and get an InvalidKeyException you need to enable unlimited strength crypto. See https://stackoverflow.com/questions/6481627/java-security-illegal-key-size-or-default-parameters for instructions.
