In this episode of My Weird Prompts, Herman and Corn explore the fascinating mathematics behind SSH keys, moving from the prime factorization of RSA to the sophisticated geometry of Elliptic Curve Cryptography (ED25519). They explain why deriving a public key from a private one is a simple calculation while the reverse would take longer than the life of the universe, illustrating the "trapdoor functions" that secure our global infrastructure. From the mechanics of digital handshakes to the physical risks of power analysis attacks, this deep dive reveals how the invisible world of number theory keeps your data safe from even the most powerful supercomputers.
