+# signal-cli

 
 

-textsecure-cli is a commandline interface for [libtextsecure-java](https://github.com/WhisperSystems/libtextsecure-java). It supports registering, verifying, sending and receiving messages. However receiving messages currently doesn't work, because libtextsecure-java [does not yet support registering for the websocket support](https://github.com/WhisperSystems/libtextsecure-java/pull/5). For registering you need a phone number where you can receive SMS.
-It is primarily intented to be used on servers to notify admins of important events.
+signal-cli is a commandline interface for the [Signal messenger](https://signal.org/).
+It supports registering, verifying, sending and receiving messages.
+signal-cli uses a [patched libsignal-service-java](https://github.com/Turasa/libsignal-service-java),
+extracted from the [Signal-Android source code](https://github.com/signalapp/Signal-Android/tree/main/libsignal-service).
+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 JSON-RPC interface ([man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli-jsonrpc.5.adoc))
+and D-BUS interface ([man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli-dbus.5.adoc)) .
+For the JSON-RPC interface there's also a simple [example client](https://github.com/AsamK/signal-cli/tree/master/client), written in Rust.
+
+signal-cli needs to be kept up-to-date to keep up with Signal-Server changes.
+The official Signal clients expire after three months and then the Signal-Server can make incompatible changes.
+So signal-cli releases older than three months may not work correctly.
+
+## Installation
+
+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. There's also a [docker image and some Linux packages](https://github.com/AsamK/signal-cli/wiki/Binary-distributions) provided by the community.
+
+System requirements:
+
+- at least Java Runtime Environment (JRE) 21
+- native library: libsignal-client
+
+  The native libs are bundled for x86_64 Linux (with recent enough glibc), Windows and MacOS. For other
+  systems/architectures
+  see: [Provide native lib for libsignal](https://github.com/AsamK/signal-cli/wiki/Provide-native-lib-for-libsignal)
+
+### Install system-wide on Linux
+
+See [latest version](https://github.com/AsamK/signal-cli/releases).
+
+```sh
+export VERSION=<latest version, format "x.y.z">
+wget https://github.com/AsamK/signal-cli/releases/download/v"${VERSION}"/signal-cli-"${VERSION}".tar.gz
+sudo tar xf signal-cli-"${VERSION}".tar.gz -C /opt
+sudo ln -sf /opt/signal-cli-"${VERSION}"/bin/signal-cli /usr/local/bin/
+```
+
+You can find further instructions on the Wiki:

 ## Usage
 
 
 ## Usage
 

-usage: textsecure-cli [-h] -u USERNAME {register,verify,send,receive} ...
+For a complete usage overview please 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).
+
+Important: The ACCOUNT is your phone number in international format and must include the country calling code. Hence it
+should start with a "+" sign. (See [Wikipedia](https://en.wikipedia.org/wiki/List_of_country_calling_codes) for a list
+of all country codes.)
+
+* Register a number (with SMS verification)
+
+      signal-cli -a ACCOUNT register
+
+  You can register Signal using a landline number. In this case, you need to follow the procedure below:
+   * Attempt a SMS verification process first (`signal-cli -a ACCOUNT register`)
+     * You will get an error `400 (InvalidTransportModeException)`, this is normal
+   * Wait 60 seconds
+   * Attempt a voice call verification by adding the `--voice` switch and wait for the call:

 
 

-* Register a number
+     ```sh
+     signal-cli -a ACCOUNT register --voice
+     ```

 
 

-        textsecure-cli -u USERNAME register
+  Registering may require solving a CAPTCHA
+  challenge: [Registration with captcha](https://github.com/AsamK/signal-cli/wiki/Registration-with-captcha)

 
 

-* Verify the number using the code received via SMS
+* Verify the number using the code received via SMS or voice, optionally add `--pin PIN_CODE` if you've added a pin code
+  to your account

 
 

-        textsecure-cli -u USERNAME verify CODE
+      signal-cli -a ACCOUNT verify CODE

 
 

-* Send a message to one or more recipients
+* Send a message

 
 

-        textsecure-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]]
+     ```sh
+     signal-cli -a ACCOUNT send -m "This is a message" RECIPIENT
+     ```

 
 * Pipe the message content from another process.
 
 
 * Pipe the message content from another process.
 

-        uname -a | textsecure-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
+      uname -a | signal-cli -a ACCOUNT send --message-from-stdin RECIPIENT
+
+* Receive messages
+
+      signal-cli -a ACCOUNT receive
+
+**Hint**: The Signal protocol expects that incoming messages are regularly received (using `daemon` or `receive`
+command). This is required for the encryption to work efficiently and for getting updates to groups, expiration timer
+and other features.
