# 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 link to an existing Signal-Android/signal-cli instance, signal-cli uses a [patched libsignal-service-java](https://github.com/AsamK/libsignal-service-java), because libsignal-service-java does not yet support [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.
signal-cli 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=
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:
- [Install on Ubuntu](https://github.com/AsamK/signal-cli/wiki/HowToUbuntu)
- [DBus Service](https://github.com/AsamK/signal-cli/wiki/DBus-service)
## Usage
Important: 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
You can register Signal using a land line 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.
* Verify the number using the code received via SMS or voice
signal-cli -u USERNAME verify CODE
* Send a message
signal-cli -u USERNAME send -m "This is a message" RECIPIENT
* Pipe the message content from another process.
uname -a | signal-cli -u USERNAME send RECIPIENT
* Receive messages
signal-cli -u USERNAME receive
For more information 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).
## Storage
The password and cryptographic keys are created when registering and stored in the current users home directory:
`$XDG_DATA_HOME/signal-cli/data/` (`$HOME/.local/share/signal-cli/data/`)
For legacy users, the old config directories are used as a fallback:
$HOME/.config/signal/data/
$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.
