Why Choose This Project

In a digital age where personal data and privacy are under constant threat, note-taking apps often leave sensitive information vulnerable. This project allows users to securely write and store notes using end-to-end encryption. It ensures that only the user can access the content, making it ideal for storing confidential thoughts, ideas, or credentials.

What You Get in This Project

A secure, user-authenticated web or mobile app for creating, editing, viewing, and deleting notes, where each note is encrypted using AES or similar encryption algorithm. Even the app admin cannot read user notes.

Technology Stack

How It Works

1. User Authentication
   Users register and log in securely with hashed credentials using bcrypt or Argon2.

2. Create & Encrypt Notes
   Notes are created and encrypted either on the client-side (before sending to the server) or server-side using AES.

3. Save to Database
   Encrypted notes are stored in the database. Only the authenticated user can decrypt them using their private key or password-derived key.

4. Edit & Decrypt Notes
   When users access a note, it's decrypted in the browser/app using the key, never revealing plaintext on the server.

5. Delete Notes Securely
   Notes can be deleted permanently with a confirmation prompt.

6. Auto Logout
   Session expiration or inactivity logs the user out for added security.
