Generating a 2048‑bit RSA key pair, encrypting with the public key, decrypting with the private key, and documenting outputs

This repository documents Priyadharshini Rengaramanujam's RSA assignment: generating a 2048-bit RSA key pair, encrypting a message with the public key, and decrypting it with the private key, including captured program output. citeturn10search1turn10search2

• docs/RSA assignment.pdf — Output evidence (screenshots/logs showing input, encrypted data, and decrypted message).
• src/rsa_encryption.py — Working Python script using the cryptography library (RSA, OAEP with SHA-256).
• BLOG.md — Lessons learned.

Quick Start

# (Optional) create a virtual environment
python -m venv .venv && source .venv/bin/activate  # Linux/macOS
# On Windows: python -m venv .venv && .venv\Scripts\activate

pip install cryptography
python src/rsa_encryption.py

The script will:

1. Generate private_key.pem and public_key.pem (2048-bit).
2. Prompt for a message, encrypt with the public key, and save as encrypted_message.bin.
3. Decrypt using the private key and print the original plaintext.
