ZenerCrypt: Quantum Random Number Generator

Description

Designed and laid out a custom PCB that enables true random number generation and RSA encryption. The design leverages quantum tunneling and the avalanche effect of a zener diode in reverse bias to extract and amplify entropy. Random bitstrings are generated from the output of a comparator. The ESP32 firmware implements the complete RSA encryption algorithm, including prime number generation using the Miller-Rabin primality test, and encryption/decryption with 2.4 GHz RF communication.
