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. To be able to receiving 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). For registering you need a phone number where you can receive SMS or incoming calls.
4 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.
8 usage: signal-cli [-h] [-u USERNAME] [-v] {register,verify,send,quitGroup,updateGroup,receive} ...
10 * Register a number (with SMS verification)
12 signal-cli -u USERNAME register
14 * Register a number (with voice verification)
16 signal-cli -u USERNAME register -v
18 * Verify the number using the code received via SMS or voice
20 signal-cli -u USERNAME verify CODE
22 * Send a message to one or more recipients
24 signal-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
26 * Pipe the message content from another process.
28 uname -a | signal-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
32 signal-cli -u USERNAME receive
38 signal-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
42 signal-cli -u USERNAME updateGroup -g GROUP_ID -n "New group name"
44 * Send a message to a group
46 signal-cli -u USERNAME send -m "This is a message" -g GROUP_ID
50 signal-cli can run in daemon mode and provides an experimental dbus interface.
51 For dbus support you need jni/unix-java.so installed on your system (Debian: libunixsocket-java ArchLinux: libmatthew-unix-java (AUR)).
53 * Run in daemon mode (dbus session bus)
55 signal-cli -u USERNAME daemon
57 * Send a message via dbus
59 signal-cli --dbus send -m "Message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
63 To run on the system bus you need to take some additional steps.
64 It’s advisable to run signal-cli as a separate unix user, the following steps assume you created a user named *signal-cli*.
65 These steps, executed as root, should work on all distributions using systemd.
68 cp data/org.asamk.Signal.conf /etc/dbus-1/system.d/
69 cp data/org.asamk.Signal.service /usr/share/dbus-1/system-services/
70 cp data/signal.service /etc/systemd/system/
71 sed -i -e "s|%dir%|<INSERT_INSTALL_PATH>|" -e "s|%number%|<INSERT_YOUR_NUMBER>|" /etc/systemd/system/signal.service
72 systemctl daemon-reload
73 systemctl enable signal.service
74 systemctl reload dbus.service
77 Then just execute the send command from above, the service will be autostarted by dbus the first time it is requested.
81 The password and cryptographic keys are created when registering and stored in the current users home directory:
83 $HOME/.config/signal/data/
85 For legacy users, the old config directory is used as a fallback:
87 $HOME/.config/textsecure/data/
91 This project uses
[Gradle](http://gradle.org) for building and maintaining
94 1. Checkout the source somewhere on your filesystem with
96 git clone https://github.com/AsamK/signal-cli.git
102 3. Create shell wrapper in *build/install/signal-cli/bin*:
104 ./gradlew installDist
106 4. Create tar file in *build/distributions*:
111 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/
