KBFS Upload API

Purpose

This API can be used to upload either secure notes or files to a secure KeybaseFS folder. The idea behind it is that files can be stored in a secure, end-to-end encrypted format without having less tech-savvy end users sign up for Keybase. This was created as a work around I needed at work so that coworkers could send me sensitive information in a secure format, but they didn't have Keybase or know how to use GPG. Creating this API and an internal web-page front end for it allowed them to send me this information and have it stored securely without teaching them anything about encryption.

Usage

Direct Launch

If you'd like to run this directly using Poetry to install it. Simply do poetry install to install it, then poetry run kbfsu to launch it.

Docker

This is also available as a Docker image. Simply run docker run -p 5000:5000 -d --restart=always dakotakae/kbfs_upload to start the server listening on port 5000.

Configuration

No matter how you launch it, some configuration will be required. This can all be done with Environment Variables.

API Interaction

The API accepts POST requests to /upload/ , where type is either note or file. Both types accept form-data as the input. Both types also require the following form entries:

• filename - The name to save the file to. This filename will be sanitized and timestamped after the fact, but is still required.
• sender - The name of the person submitting the form.

You can also send recipient to identify the intended recipient of the file. This is an arbitrary string and does not have to be a particular Keybase username.

If type is note, the request also needs to include a body field that contains the text to be stored. If the type is file, the uploaded file must be sent with the file key.

This is all the reference needed to build your own front-end for this api.

Development/Contribution

As stated before, Poetry is used to manage the project. If there are any improvements/changes to be made, feel free to submit a PR.
