Explore the fundamentals of public key cryptography in this comprehensive 1 hour 21 minute lecture. Delve into the origins of public key methods, their current challenges, and the emergence of post-quantum cryptography. Learn about the three main public key methods: RSA, ECC, and ElGamal. Gain practical insights into RSA's functionality, Python implementation, and the management of public keys. Discover the use of keyrings and GPG (GNU Privacy Guard) for secure communication. Access additional resources on RSA, ECC, and ElGamal through provided links to enhance your understanding of these critical cryptographic techniques.
