Password Cracking and Hashing Algorithms 🔐

🛡️ Password Cracking & Hashing Algorithms 🚀

Internship Project for Codec Technologies
Learn, implement, and test password security algorithms in Python! ⚡
Covers MD5, SHA-256, SHA-512, bcrypt, salting, and password cracking (dictionary & brute force).
_{Tech Stack: Python, Hashlib, Bcrypt, Pytest}

---

🧠 Introduction

Developed as part of my internship with Codec Technologies, this project provides hands-on implementations of password hashing & cracking techniques.
It demonstrates secure hashing (with & without salting) and showcases how password cracking is attempted using brute force and dictionary attacks.
