KyberLib and the Post-Quantum Banking Migration in 2026: From Standards to Code

KyberLib turns the post-quantum banking migration from policy paper into inspectable Rust — FIPS 203 ML-KEM key encapsulation, hybrid classical-plus-quantum handshakes, no_std compilation for HSMs, crypto-agile abstraction boundaries, and the DORA Article 5 governance evidence boards now need.

Post-Quantum Payments Infrastructure: Why Banks May Replace Rather Than Retrofit Legacy Rails

Harvest-now-decrypt-later turns today's TLS-protected payment messages into tomorrow's decrypted exposure. ML-KEM and ML-DSA are an order of magnitude larger than the RSA and ECC keys legacy rails were sized for — retrofit triggers fragmentation, latency, and HSM exhaustion. The 2026 architectural decision is whether to patch or replace before the regulatory clock runs out.
