post-quantum-cryptography

Post-quantum cryptography swaps RSA and elliptic-curve public-key schemes for NIST-standardized ML-KEM, ML-DSA and SLH-DSA. Sizes, timelines, limits.

A sufficiently powerful quantum computer could break the encryption that secures banking, communications, and national security in seconds. The threat is real but limited to specific algorithms — and the cryptographic world is racing to deploy quantum-resistant alternatives before the day arrives.
