🔐 Java Hash Generator

A Java console application for generating and comparing cryptographic hashes using the Java Security MessageDigest API.

This project demonstrates the fundamentals of cryptographic hashing and Java Object-Oriented Programming (OOP) through a simple, menu-driven console interface.

---

✨ Features

• 🔑 Generate cryptographic hashes from user input.
• 🔍 Compare two hash values.
• 📚 Display all MessageDigest algorithms supported by the installed JDK.
• 🛡️ Support for multiple hashing algorithms, including SHA-2 and SHA-3.
• 🖥️ Interactive menu-driven console application.

🔐 Supported Algorithms

• MD2
• MD5
• SHA-1
• SHA-224
• SHA-256
• SHA-384
