# Cryptography Comparative Analysis  

A performance and security analysis of various cryptographic algorithms, including **hashing, symmetric encryption, and asymmetric encryption**. The study evaluates algorithm efficiency based on **speed, resource usage, collision resistance, and brute-force resistance** using practical experiments in Python.

## Tech Stack  

- Python  

- matplotlib (Data Visualization)  

- hashlib (Hashing)  

- cryptography (Encryption)  

- psutil (Resource Monitoring)  

- csv (Data Storage)
