Encryption App

Abstract

1. Introduction

The Encryption and Decryption App is a free and user-friendly web application that allows you to encrypt and decrypt files using a password of your choice. Whether you need to protect sensitive data or secure your personal files, this app provides a convenient solution.

Although the final site is different from my initial design in Figma, I'm still satisfied by the result. Check out the design on Behance here.

2. Objective

Encrypt.tn - free file encryption & decryption.

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

3. Key Features / Modules

• File Encryption: Select a file or drag-and-drop it onto the app's interface, then enter a password to encrypt it securely.
• File Decryption: Decrypt encrypted files by providing the correct password.
• User-friendly Interface: The app is built with HTML, CSS, Bootstrap 5, and JavaScript, ensuring a seamless and intuitive user experience.
• Built-in Crypto Functions: Leveraging JavaScript's built-in cryptographic functions, the app ensures robust encryption and decryption processes.

4. Technology Stack

• Bootstrap 5
• JavaScript
• JavaScript Crypto Functions

5. System Requirements

General requirements for this technology stack — check the README for exact versions.
