Asymmetric cryptography

More specifically, post-quantum cryptography.

That’s a “bet” on something that everyone is sure about, so not much of a bet!

Most people don't believe a cryptographically-relevant quantum computer will ever exist as an real world engineering artifact.

If NSA believed it were possible, they would not publicly promote research on post-quantum cryptography, the would crack quantum cryptography.

> NIST calls its draft standard Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM). However, at least for Kyber512, there are claims that NIST's security calculations were amiss.
