-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. To be able to receive messages signal-cli uses a [patched libsignal-service-java](https://github.com/AsamK/libsignal-service-java), because libsignal-service-java [does not yet support registering for the websocket support](https://github.com/WhisperSystems/libsignal-service-java/pull/5) nor [provisioning as a slave device](https://github.com/WhisperSystems/libsignal-service-java/pull/21). 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. For this use-case, it has a dbus interface, that can be used to send messages from any programming language that has dbus bindings.

-
-* Send a message to one or more recipients
-
-        signal-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
-
-* Pipe the message content from another process.
-
-        uname -a | signal-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
-        
-* Receive messages
-
-        signal-cli -u USERNAME receive
-
-* Groups
-
- * Create a group
-
-          signal-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
-
- * Update a group
+You can find further instructions on the Wiki:

 
 

-          signal-cli -u USERNAME updateGroup -g GROUP_ID -n "New group name" -a "AVATAR_IMAGE_FILE"
+- [Quickstart](https://github.com/AsamK/signal-cli/wiki/Quickstart)

 
 

- * Add member to a group
-
-          signal-cli -u USERNAME updateGroup -g GROUP_ID -m "NEW_MEMBER"
-
- * Leave a group

-
-* Linking other devices (Provisioning)
-
- * Connect to another device
-
-          signal-cli link -n "optional device name"
-        
-        This shows a "tsdevice:/…" link, if you want to connect to another signal-cli instance, you can just use this link. If you want to link to and Android device, create a QR code with the link (e.g. with [qrencode](https://fukuchi.org/works/qrencode/)) and scan that in the Signal Android app.
-
- * Add another device
+## Usage

 
 

-          signal-cli -u USERNAME addDevice --uri "tsdevice:/…"
-          
-        The "tsdevice:/…" link is the one shown by the new signal-cli instance or contained in the QR code shown in Signal-Desktop or similar apps.
-        Only the master device (that was registered directly, not linked) can add new devices.
+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).

 
 

- * Manage linked devices
+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.)

 
 

-          signal-cli -u USERNAME listDevices
+* Register a number (with SMS verification)

 
 

-          signal-cli -u USERNAME removeDevice -d DEVICE_ID
+      signal-cli -a ACCOUNT register

 
 

-* Manage trusted keys
+  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.

 
 

- * View all known keys
+  Registering may require solving a CAPTCHA
+  challenge: [Registration with captcha](https://github.com/AsamK/signal-cli/wiki/Registration-with-captcha)

 
 

-          signal-cli -u USERNAME listIdentities
+* 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

 
 

- * View known keys of one number
+      signal-cli -a ACCOUNT verify CODE

 
 

-          signal-cli -u USERNAME listIdentities -n NUMBER
+* Send a message

 
 

- * Trust new key, after having verified it
+     ```sh
+     signal-cli -a ACCOUNT send -m "This is a message" RECIPIENT
+     ```

 
 

-          signal-cli -u USERNAME trust -v FINGER_PRINT NUMBER
+* Pipe the message content from another process.

 
 

- * Trust new key, without having verified it. Only use this if you don't care about security
+      uname -a | signal-cli -a ACCOUNT send --message-from-stdin RECIPIENT

 
 

-          signal-cli -u USERNAME trust -a NUMBER
+* Receive messages

 
 

-* Set configuration directory
+      signal-cli -a ACCOUNT receive

 
 

-          signal-cli --config=/home/other_user/.config/signal
+**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.

 
 

-        This is particularily useful in the case, when you would like to run the signal-cli tool as a different user as the one, that was used to register the account. You should make sure, that the caller has full read/write access to the given directory.

-## DBus service
+## Storage

 
 

-signal-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)).
+The password and cryptographic keys are created when registering and stored in the current users home directory:

 
 

-* Run in daemon mode (dbus session bus)
+    $XDG_DATA_HOME/signal-cli/data/
+    $HOME/.local/share/signal-cli/data/

 
 

-          signal-cli -u USERNAME daemon
+## Building

 
 

-* Send a message via dbus
+This project uses [Gradle](http://gradle.org) for building and maintaining dependencies. If you have a recent gradle
+version installed, you can replace `./gradlew` with `gradle` in the following steps.

 
 

-          signal-cli --dbus send -m "Message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
+1. Checkout the source somewhere on your filesystem with

 
 

-### System bus
+       git clone https://github.com/AsamK/signal-cli.git

 
 

-To run on the system bus you need to take some additional steps.
-It’s advisable to run signal-cli as a separate unix user, the following steps assume you created a user named *signal-cli*.
-These steps, executed as root, should work on all distributions using systemd.
+2. Execute Gradle:

 
 

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

 
 

-Then just execute the send command from above, the service will be autostarted by dbus the first time it is requested.
+   2a. Create shell wrapper in *build/install/signal-cli/bin*:

 
 

-## Storage
+       ./gradlew installDist

 
 

-The password and cryptographic keys are created when registering and stored in the current users home directory:
+   2b. Create tar file in *build/distributions*:

 
 

-        $HOME/.config/signal/data/
+       ./gradlew distTar

 
 

-For legacy users, the old config directory is used as a fallback:
+   2c. Create a fat tar file in *build/libs/signal-cli-fat*:

 
 

-        $HOME/.config/textsecure/data/
+       ./gradlew fatJar

 
 

-## Building
+   2d. Compile and run signal-cli:

 
 

-This project uses [Gradle](http://gradle.org) for building and maintaining
-dependencies. If you have a recent gradle version installed, you can replace `./gradlew` with `gradle` in the following steps.
+      ```sh
+      ./gradlew run --args="--help"
+      ```

-        git clone https://github.com/AsamK/signal-cli.git
+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 environment](https://www.graalvm.org/docs/getting-started/#install-graalvm)

+## FAQ and Troubleshooting

 
 

-## Troubleshooting
-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.
