-# textsecure-cli
+# 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 only works with a patched libtextsecure-java, 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 or incoming calls.
-It is primarily intended 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.

 
 

-## Usage
-
-usage: textsecure-cli [-h] [-u USERNAME] [-v] {register,verify,send,quitGroup,updateGroup,receive} ...
+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](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli-dbus.5.adoc)) and JSON-RPC 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.

 
 

-* Register a number (with SMS verification)
+## Installation

 
 

-        textsecure-cli -u USERNAME register
+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.

 
 

-* Register a number (with voice verification)
+System requirements:

 
 

-        textsecure-cli -u USERNAME register -v
+- at least Java Runtime Environment (JRE) 17
+- native library: libsignal-client

 
 

-* Verify the number using the code received via SMS or voice
+  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)

 
 

-        textsecure-cli -u USERNAME verify CODE
+### Install system-wide on Linux

 
 

-* Send a message to one or more recipients
+See [latest version](https://github.com/AsamK/signal-cli/releases).

 
 

-        textsecure-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
-
-* Pipe the message content from another process.
+```sh
+export VERSION=<latest version, format "x.y.z">
+wget https://github.com/AsamK/signal-cli/releases/download/v"${VERSION}"/signal-cli-"${VERSION}"-Linux.tar.gz
+sudo tar xf signal-cli-"${VERSION}"-Linux.tar.gz -C /opt
+sudo ln -sf /opt/signal-cli-"${VERSION}"/bin/signal-cli /usr/local/bin/
+```

 
 

-        uname -a | textsecure-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
+You can find further instructions on the Wiki:

 
 

-* Groups
+- [Quickstart](https://github.com/AsamK/signal-cli/wiki/Quickstart)
+- [DBus Service](https://github.com/AsamK/signal-cli/wiki/DBus-service)

 
 

- * Create a group
+## Usage

 
 

-          textsecure-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
+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).

 
 

- * Update a group
+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.)

 
 

-          textsecure-cli -u USERNAME updateGroup -g GROUP_ID -n "New group name"
+* Register a number (with SMS verification)

 
 

- * Send a message to a group
+        signal-cli -a ACCOUNT register

 
 

-          textsecure-cli -u USERNAME send -m "This is a message" -g GROUP_ID
+  You can register Signal using a landline 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.

 
 

-## DBus service
+  Registering may require solving a CAPTCHA
+  challenge: [Registration with captcha](https://github.com/AsamK/signal-cli/wiki/Registration-with-captcha)

 
 

-textsecure-cli can run in daemon mode and provides an experimental dbus interface.
-For dbus support you need jni/unix-java.so installed on your system (Debian: libunixsocket-java ArchLinux: libmatthew-unix-java (AUR)).
+* 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

 
 

-* Run in daemon mode (dbus session bus)
+        signal-cli -a ACCOUNT verify CODE

 
 

-          textsecure-cli -u USERNAME daemon
+* Send a message

 
 

-* Send a message via dbus
+        signal-cli -a ACCOUNT send -m "This is a message" RECIPIENT

 
 

-          textsecure-cli --dbus send -m "Message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
+* Pipe the message content from another process.

 
 

-### System bus
+        uname -a | signal-cli -a ACCOUNT send --message-from-stdin RECIPIENT

 
 

-To run on the system bus you need to take some additional steps.
-It’s advisable to run textsecure-cli as a separate unix user, the following steps assume you created a user named *textsecure*.
-These steps, executed as root, should work on all distributions using systemd.
+* Receive messages

 
 

-```bash
-cp data/org.asamk.TextSecure.conf /etc/dbus-1/system.d/
-cp data/org.asamk.TextSecure.service /usr/share/dbus-1/system-services/
-cp data/textsecure.service /etc/systemd/system/
-sed -i -e "s|%dir%|<INSERT_INSTALL_PATH>|" -e "s|%number%|<INSERT_YOUR_NUMBER>|" /etc/systemd/system/textsecure.service
-systemctl daemon-reload
-systemctl enable textsecure.service
-systemctl reload dbus.service
-```
+        signal-cli -a ACCOUNT receive

 
 

-Then just execute the send command from above, the service will be autostarted by dbus the first time it is requested.
+**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.

+### Building a native binary with GraalVM (EXPERIMENTAL)
+
+It is possible to build a native binary with [GraalVM](https://www.graalvm.org). This is still experimental and will not
+work in all situations.
+
+1. [Install GraalVM and setup the enviroment](https://www.graalvm.org/docs/getting-started/#install-graalvm)
+2. [Install prerequisites](https://www.graalvm.org/reference-manual/native-image/#prerequisites)
+3. Execute Gradle:
+
+        ./gradlew nativeCompile
+
+   The binary is available at *build/native/nativeCompile/signal-cli*
