THIS IMPLEMENTATION OF THE RSA ALGORITHM IS MISSING VITAL SECURITY FEATURES. IT IS NOT SECURE. FOR EDUCATIONAL PURPOSES ONLY.

This project includes:

• An RSA key generator.
• A Flask server which listens for incoming encrypted messages.
• A client which sends encrypted messages to the above server.

The project is inspired by the exposition of the RSA cryptosystem in 'Understanding Cryptography', A Textbook for Students and Practitioners by Christof Paar, Jan Pelzl, Bart Preneel (ISBN: 8601406549616).

Run the following to log a set of RSA keys to the terminal:

python -m key_generator.main

Paste the PRIVATE_EXPONENT and MODULUS generated above into server/settings.py then run

python -m server.api.main

Incoming messages are listened to at /. To be processed POST the following to /

{
  "ciphertext": CIPHERTEXT GOES HERE
}

Incoming messages will be logged to server/message_log.txt

Paste the PUBLIC_EXPONENT and MODULUS generated above into client/settings.py. Also specify a URI to send the encrypted message to.

Insert some plaintext into client/plaintext_payload.txt and run

python -m server.api.main
