#RSA From Scratch (No Crypto Libraries)

This project implements RSA public-key cryptography from scratch in Python, using byte-wise encryption, and manual modular inverse calculation. This is a resurrection of a project I started developing in 2015.

##Features

• Pure Python - No external dependencies
• Base64-encoded ciphertext output
• Full encryption/decryption loop
• Educational, readable, and hackable

!!Not Production-Safe!!

This code is built for education and transparency, not for secure deployment. Avoid using it for real cryptographic workloads.

##Why Use This?

Unlike most RSA libraries, this project shows you everything:

• How prime numbers are tested
• How the public/private keys are calculated
• How plaintext becomes ciphertext
• How decryption works, byte by byte

##Usage
