ACU Kriptografi
An interactive web application enabling users to encrypt and decrypt messages seamlessly using popular cryptographic algorithms like AES, RSA, and RC4.
Overview
ACU (Application Crypto Universe) is an interactive web-based security application designed to help users easily encrypt and decrypt messages. It leverages popular cryptographic algorithms such as AES, RSA, and RC4 to provide robust text data protection.
Built with a focus on usability, ACU features a user-friendly and responsive interface suitable for both desktop and mobile devices.

Key Features
- Multi-Algorithm Support: Encrypt and decrypt messages using industry-standard algorithms:
- AES (Advanced Encryption Standard)
- RSA (Rivest–Shamir–Adleman)
- RC4 (Stream Cipher)
- Encryption History: A dedicated sidebar that locally stores your encryption and decryption history for quick reference.
- Responsive Design: Optimized interface offering a seamless experience across desktop and mobile platforms.
- Live Chat: Integrated live chat functionality for real-time communication.
- Download Results: Easily download the encrypted or decrypted text output directly to your device.
Tech Stack
The application is built leveraging modern web development tools:
- React.js — The core framework for building the dynamic user interface.
- Vite — A modern build tool ensuring rapid development and optimized production builds.
- Tailwind CSS — A utility-first CSS framework for rapid UI styling and responsive design.
- JavaScript — Handles the core cryptographic logic and algorithms.
- LocalStorage — Used to securely store the history of encryption processes directly within the user's browser.
