PortWarden

Build Status

This project creates encrypted backups for (Bitwarden)[https://bitwarden.com/] vaults including attachments. It pulls your vault items from (Bitwarden CLI)[https://github.com/bitwarden/cli] and download all the attachments associated with those items to a temporary backup folder. Then, portwarden zip that folder, encrypt it with a passphrase, and delete the temporary folder.

It addresses this issue in the community forum https://community.bitwarden.com/t/encrypted-export/235, but hopefully Bitwarden will come up with official solutions soon.

Usage Of Portwarden CLI

Go to https://github.com/bitwarden/cli/releases to download the latest version of Bitwarden CLI and place the executable bw/bw.exe in your PATH. Then, go to https://github.com/vwxyzjn/portwarden/releases/ to downlaod the latest release of portwarden. Now just follow the steps in the following Gif:

alt text

portwarden --passphrase 1234 --filename backup.portwarden encrypt
portwarden --passphrase 1234 --filename backup.portwarden decrypt

Usage of Portwarden Server (Setup Scheduled Backup)

Make sure you have Docker installed and ports 8000, 8081, 5000 unused. Then download https://github.com/vwxyzjn/portwarden/blob/master/k8s/docker-compose.build.yaml to a folder and ❗ name the file docker-compose.yaml ❗ and run

costa@DESKTOP-M991V0B MINGW64 ~
$ # Make sure your server has docker installed.

costa@DESKTOP-M991V0B MINGW64 ~
$ ssh -L 8000:temp2uk4muy.costa.sh:8000 -L 8081:temp2uk4muy.costa.sh:8081 -L 5000:temp2uk4muy.costa.sh:5000 costa@temp2uk4muy.costa.sh

After the services are spinned up, go to http://localhost:8000 and follow the steps to setup scheduled backups.

You will probably have to host Portwarden Server on your machine. One caveat is that Portwarden Server does store your encryption key (not your master password) and I don't feel comfortable managing your credentials. This server is really for my personal use and a demonstration of the modern architecture for my Software Design class (see below)

Portwarden Compared with Official Bitwarden Backup (As of 12/5/2018)

Portwarden Official Bitwarden Backup
Backend golang C#
Backup Format ✔️ AES-Encrypted .portwarden format Unencrypted CSV file
Backup With Attachments ✔️ Not supported (see this feature request)
Scheduled Backup ✔️ Use Portwarden Server (Experimental) Not supported

Contribution & Development

Clone this repo. Make sure you have Docker installed, ports 8000, 8081, 5000 unused, Golang installed, dep installed. In addition, create an environment varialble Salt of length 30 for encryption salt. Then run

dep ensure           # Install go dependencies
docker-compose up -d # Spin up required containers

# After the services/containers are created successfully, you should see
# $ docker-compose up  -d
# WARNING: Some services (worker) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.

Notice the docker-compose.yaml file defines the services running and it's mounting your current directory as volumes and map it to the container's working directory. This means you can develop/make changes in your local machine, and run it in the container. It also maps certain containers' ports into your host so that you can call the endpoints.

PRs are welcome. For ideas, you could probably add a progress bar to the CLI.

Project Proposal for Software Design Course (SE-575) at Drexel University

This section is experimental and for fun.

I currently taking this class, and our final project is suppose to demonstrate some traits of the modern software architecture. So my teammate Samridh Prasad and I figure we can probably add some components to Portwarden to make it more interesting. Couple initial deliverables are listed below:

Backend server

  • Write a backend server by Go in the portwarden/web folder.
  • Allow Bitwarden User to login and periodically back up their vault to Google Drive.
  • If the user has attachments, download them in every 300 milliseconds because we don't want to get blacklisted. This means we probably want a queue (Maybe use Kafka?) as part of the architecture.
  • Use Let's encrypt to make the server use HTTPS protocal.

Frontend

  • Has a simple front end that gets user's username and password and show them if the backup process has begun.
  • Allow the user to cancel such backup process if he/she wants.

System Architecture

We tried to avoid being boxed by a layered architecture and strived to conform to C4 standards best we could and ensured the code reflects the architecture. Overall, we found the lectures and assigned readings to greatly improve our ability to design scalable system architecture.
