Abstract

Portable Secret is an open-source Cybersecurity & Ethical Hacking project. Better privacy without special software. I created Portable Secret to securely exchange documents via email with my mother, who can't be expected to learn PGP, age, or similar. It is built using HTML, JavaScript. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction

I created Portable Secret to securely exchange documents via email with my mother, who can't be expected to learn PGP, age, or similar.

I also use Portable Secret to store some my most sensitive secrets (private keys, 2FA recovery codes, etc.)

Portable Secret is not a product and it is barely a project.

2. Objective

Better privacy without special software

This project demonstrates how HTML, JavaScript can be applied to a real-world Cybersecurity & Ethical Hacking problem.
