# textsecure-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.
## Usage
usage: textsecure-cli [-h] [-u USERNAME] [-v] {register,verify,send,quitGroup,updateGroup,receive} ...
* Register a number (with SMS verification)
textsecure-cli -u USERNAME register
* Register a number (with voice verification)
textsecure-cli -u USERNAME register -v
* Verify the number using the code received via SMS or voice
textsecure-cli -u USERNAME verify CODE
* Send a message to one or more recipients
textsecure-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
* Pipe the message content from another process.
uname -a | textsecure-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
* Groups
* Create a group
textsecure-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
* Update a group
textsecure-cli -u USERNAME updateGroup -g GROUP_ID -n "New group name"
* Send a message to a group
textsecure-cli -u USERNAME send -m "This is a message" -g GROUP_ID
## DBus service
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)).
* Run in daemon mode (dbus session bus)
textsecure-cli -u USERNAME daemon
* Send a message via dbus
textsecure-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.
Its advisable to run textsecure-cli as a separate unix user, the following steps assume you created a user named *textsecure-cli*.
These steps, executed as root, should work on all distributions using systemd.
```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
```
Then just execute the send command from above, 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/textsecure/data/
## Building
This project uses [Gradle](http://gradle.org) for building and maintaining
dependencies.
1. Checkout the source somewhere on your filesystem with
git clone https://github.com/AsamK/textsecure-cli.git
2. Execute Gradle:
./gradlew build
3. Create shell wrapper in *build/install/textsecure-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.
