# 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

## 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.
