M7
ML-DSA (Dilithium) Signatures — Replacing RSA and ECDSA in Code Signing, JWT, and PKI
ML-DSA (FIPS 204) replaces RSA and ECDSA for digital signatures. How lattice signatures work, three security levels, size impact on TLS/JWT/code-signing, the migration playbook. Module 7.
Intermediate 40 min →
M8
SLH-DSA (SPHINCS+) — Hash-Based Signatures for the Long Haul
SLH-DSA (FIPS 205) is the conservative hash-based PQ signature alternative — security rests on hash functions only, no lattice assumptions. When to use it (root CAs, firmware), when not to (TLS, JWT). Module 8.
Intermediate 35 min →
M9
Hybrid PQ Deployment — TLS, SSH, IPsec, S/MIME with Classical + ML-KEM Together
Run classical (X25519) + post-quantum (ML-KEM-768) in the same handshake. Adversary needs both to break. Concrete configs for nginx, OpenSSH, strongSwan, Cloudflare. Migration checklist. Module 9.
Intermediate 45 min →
M10
Quantum Key Distribution (QKD) — Hype vs Reality, and Why PQ Cryptography Wins
QKD uses photonics for physics-based key exchange. Marketing pitches it as uncrackable. Reality: dedicated fibre, expensive, doesnt authenticate, and ML-KEM solves the same problem cheaper. When QKD makes sense (rarely). Module 10.
Intermediate 30 min →
