Databag is a self-hosted messaging service. Notable features include:
- Public-private key based identity (not bound to any blockchain or hosting domain)
- End-to-end encryption (the hosting admin cannot view sealed topics)
- Audio and Video Calls (enabled with separate relay server)
- Federated (accounts on different nodes can communicate)
- Topic based threads (messages organized by topic not contacts)
- Lightweight (server runs on a raspberry pi zero v1.3)
- Decentralized (direct communication between app and contact's node)
- Low latency (use of websockets for push events to avoid polling)
- Responsive (renders well on phone, tablet and pc)
- Unlimited accounts per node (host for your whole family)
- Mobile alerts (push notifications on new contacts and messages)

The app is available in the google and apple stores. You can also test out the project [here](https://databag.coredb.org/#/create), but don't post anything important as this server is regularly wiped. Feedback on the UI/UX, bugs or features is greatly appreciated.

## Installation

To use databag, you will need a DNS name pointing to your node with a certificate. You can deploy a node manually, but you will have a much easier time using a container service. Containers for arm64 and amd64 are available [here](https://hub.docker.com/r/balzack/databag/tags). 

### Docker Compose Command

From the net/container sub directory:
  - sudo docker-compose -f compose.yaml -p databag up

### Example with Portainer and Nginx Proxy Manager

From Portainer:
  - In the volume view, click add volumen:
    - Enter a name, then click 'Create the volume'
  - In the container view, click add container:
    - In the 'Image' field enter 'balzack/databag:latest'
    - Click 'publish a new network port', and select port 7000 for both host and container
    - Under 'Advanced container settings', select 'Env', and click 'Add Environment Variable'
      - Enter 'Name' as 'ADMIN' and your admin password [password]
    - Under 'Advanced container settings', select 'Volumes', then 'map additional volume'
      - Enter '/var/lib/databag' for 'container' and the created volume for 'volume'
    - Click 'Deploy the Container'

From Nginx Proxy Manager:
  - Add a host and specify:
    - Hostname [hostname.domain]
    - Portainer IP address [address]
    - Port '7000'
    - Request new SSL certificate

From Your Browser:
  - Enter your server address in the address bar [hostname.domain]
    - Click the cog icon in the top right
    - Enter your admin password: [password]
    - Click the cog icon in the dashboard
      - Enter Federated Host as [hostname.domain]
      - Click 'Save'
    - Click the user icon to generate a new account link
      - Follow the link to create an account

### Other installation options

Instruction for installing without a container on a Raspberry Pi Zero are [here](/doc/pizero.md).

Instruction for installing without a container in AWS are [here](/doc/aws.md).

## Audio and Video Calls

Databag depends on a separate STUN/TURN relay server to provide audio and video calls. We've tested with both [cuturn](https://github.com/coturn/coturn) and [pion](https://github.com/pion/turn), but you should be able to use any implementation. Instruction for installing a coturn server are provided [here](https://gabrieltanner.org/blog/turn-server/).

If you want to enable audio and video calls, you need setup your own relay server. For testing purposes you can however use the demo relay server:
  - WebRTC Server URL: turn:34.210.172.114:3478?transport=udp
  - WebRTC Username: user
  - WebRTC Password: pass
