RSA Simulation & CCA Attack Demo

An interactive web-based simulation demonstrating RSA encryption/decryption and the Chosen Ciphertext Attack (CCA) exploit.

Features

• RSA Encryption/Decryption: Encrypt ASCII codes and see the step-by-step RSA process
• Chosen Ciphertext Attack (CCA): Interactive demo of how RSA malleability can be exploited to recover plaintext
• Educational: Shows the mathematical operations (modular exponentiation, modular inverse) in action

Tech Stack

• React 18
• Vite
• React Router
• BigInt for cryptographic math

Getting Started

npm install
npm run dev

RSA Parameters

• Prime p: 3557
• Prime q: 2579
• Public exponent e: 65537
• Uses fixed primes for demonstration purposes

Security Note

This is an educational simulation. The fixed primes and lack of padding make it unsuitable for any real cryptographic use.
