This challenge was about breaking a custom public key encryption system.
graphs Cryptography (200 pts) -------------- In this era, block ciphers hadn't even been invented. The Plague created this system based on problems he knew to be NP hard, but there must be something you can do to decode his messages.
We were given a python implementation of the system, the Plague’s public key and an encrypted message. The implementation includes encryption, decryption (given a private key) and key generation.
