0xNotes Monorepo

0xNotes is a free and open-source, privacy-focused, end-to-end encrypted note-taking web app built with Next.js and Python.

Features

Formatted text support: Bold, italic, underline, add images, embed youtube, and more...
End-to-end encryption: Each note is encrypted locally with AES-CTR-256, currently one of the most secure encryption. The encryption key is derived from your username and password and stored locally on your browser. This means, hackers need to try 2^256 combinations to read your notes.
Two-factor authentication: Secure your account by enabling Google Authenticator. You will be required to enter a 6-digit code every time you log in.

Deploy

This tutorial is only for advanced users that want to self host 0xNotes. You'll need a web host that supports Next.js and a server that can run docker. HTTPS connection is highly recommended, but the frontend MUST USE HTTPS.

Database

Create a PostgreSQL database.
Manually create tables:

CREATE TABLE notes (
    id bigserial primary key not null,
    author text,
    modified timestamp with time zone not null default now(),
    note text,
    notes_nonce text,
    server_nonce text,
    title text,
    title_nonce text,
    type text
);

CREATE TABLE users (
    id bigserial primary key not null,
    username text,
    auth text,
    totp text
);

Backend

Clone and switch to the server branch of this repo.
Create a docker image by using docker build -t 0xnotes:latest ..
Create a docker-compose.yml file using the following template, add configuration for reverse proxy (NGINX or Traefik) if required.

version: "3.3"

services:
  notes:
    image: 0xnotes
    restart: always
    container_name: 0xnotes
    ports:
      - "5000:5000"
    networks:
      - web
    environment:
      - "POSTGRES_URL={POSTGRES_URL}"
      - "SERVER_SECRET={SECRET_RANDOM_STRING}"
      - "SERVER_SALT={SECRET_RANDOM_STRING}"

networks:
  web:
    external: true

Run the docker image using docker-compose up -d
