# signal-cli
|
||
|
||
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.
|
||
|
||
## 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. 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.
|
||
|
||
### 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/
|
||
```
|
||
|
||
## Usage
|
||
|
||
usage: signal-cli [-h] [-v] [--config CONFIG] [-u USERNAME | --dbus | --dbus-system] {link,addDevice,listDevices,removeDevice,register,verify,send,quitGroup,updateGroup,listIdentities,trust,receive,daemon} ...
|
||
|
||
See also: [man page in asciidoc format](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli.1.txt)
|
||
|
||
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.
|
||
|
||
* Register a number (with SMS verification)
|
||
|
||
signal-cli -u USERNAME register
|
||
|
||
* Register a number (with voice verification)
|
||
|
||
signal-cli -u USERNAME register -v
|
||
|
||
* Verify the number using the code received via SMS or voice
|
||
|
||
signal-cli -u USERNAME verify CODE
|
||
|
||
* 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
|
||
|
||
signal-cli -u USERNAME updateGroup -g GROUP_ID -n "New group name" -a "AVATAR_IMAGE_FILE"
|
||
|
||
* Add member to a group
|
||
|
||
signal-cli -u USERNAME updateGroup -g GROUP_ID -m "NEW_MEMBER"
|
||
|
||
* Leave a group
|
||
|
||
signal-cli -u USERNAME quitGroup -g GROUP_ID
|
||
|
||
* Send a message to a group
|
||
|
||
signal-cli -u USERNAME send -m "This is a message" -g GROUP_ID
|
||
|
||
* 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
|
||
|
||
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.
|
||
|
||
* Manage linked devices
|
||
|
||
signal-cli -u USERNAME listDevices
|
||
|
||
signal-cli -u USERNAME removeDevice -d DEVICE_ID
|
||
|
||
* Manage trusted keys
|
||
|
||
* View all known keys
|
||
|
||
signal-cli -u USERNAME listIdentities
|
||
|
||
* View known keys of one number
|
||
|
||
signal-cli -u USERNAME listIdentities -n NUMBER
|
||
|
||
* Trust new key, after having verified it
|
||
|
||
signal-cli -u USERNAME trust -v FINGER_PRINT NUMBER
|
||
|
||
* Trust new key, without having verified it. Only use this if you don't care about security
|
||
|
||
signal-cli -u USERNAME trust -a NUMBER
|
||
|
||
* Set configuration directory
|
||
|
||
signal-cli --config=/home/other_user/.config/signal
|
||
|
||
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
|
||
|
||
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)).
|
||
|
||
* Run in daemon mode (dbus session bus)
|
||
|
||
signal-cli -u USERNAME daemon
|
||
|
||
* Send a message via dbus
|
||
|
||
signal-cli --dbus send -m "Message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
|
||
|
||
### System bus
|
||
|
||
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.
|
||
|
||
Mind the fact that signal.service executes the signal-cli with "--config /var/lib/signal-cli".
|
||
If you registered with user signal-cli, remove the config option.
|
||
|
||
```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
|
||
```
|
||
|
||
Make sure to use "--dbus-system" with the send command, the service will be autostarted by dbus the first time it is requested.
|
||
|
||
## Storage
|
||
|
||
The password and cryptographic keys are created when registering and stored in the current users home directory:
|
||
|
||
$HOME/.config/signal/data/
|
||
|
||
For legacy users, the old config directory is used as a fallback:
|
||
|
||
$HOME/.config/textsecure/data/
|
||
|
||
## Building
|
||
|
||
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.
|
||
|
||
1. Checkout the source somewhere on your filesystem with
|
||
|
||
git clone https://github.com/AsamK/signal-cli.git
|
||
|
||
2. Execute Gradle:
|
||
|
||
./gradlew build
|
||
|
||
3. Create shell wrapper in *build/install/signal-cli/bin*:
|
||
|
||
./gradlew installDist
|
||
|
||
4. Create tar file in *build/distributions*:
|
||
|
||
./gradlew distTar
|
||
|
||
## 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.
