A practical, working-engineer's look at where post-quantum cryptography actually stands in mid-2026: what NIST shipped in FIPS 203/204/205, the Module-LWE math behind ML-KEM and ML-DSA at a level you can defend in a code review, the hybrid TLS and SSH deployments already moving real traffic, and the honest cost of the migration in bytes, milliseconds, and operational pain.
