Quantum cryptography learning guide

Week 1 — The threat (Shor's and Grover's)

Checkpoint: Explain why RSA breaks but AES-256 mostly survives.

---

Week 2 — HNDL urgency (Mosca inequality)

Checkpoint: Apply X + Y > Z to one data class from your retention policy.

---

Week 3 — NIST standards (FIPS 203–205)

Checkpoint: Name ML-KEM, ML-DSA, and SLH-DSA and what each replaces.

---

Week 4 — Migration in practice

Checkpoint: Describe hybrid TLS and list three non-HTTPS crypto locations in your estate.
