Cryptography & PKI · modules
Modern crypto primitives, TLS, PKI architecture, secrets management at scale.
Module 9 · Key Management at Scale
Crypto without good key management is decoration. Every breach has a “where did the keys live” question. The hierarchy of safety HSM (FIPS 140-3 Level 2-4) — most secure; keys never leave hardware Cloud KMS — managed; keys logically scoped; audit trails HashiCorp Vault — flexible; software-based; supports HSM backend Application-level keystore — least secure […]
Module 10 · Quantum-Safe Cryptography Readiness
Quantum computers will break RSA and elliptic curve crypto. NIST published post-quantum standards in 2024. Migration is a multi-year project. The NIST winners ML-KEM (Kyber) — key encapsulation; replaces RSA-KEM and ECDH ML-DSA (Dilithium) — digital signatures; replaces RSA-PSS, ECDSA SLH-DSA (SPHINCS+) — alternative signature; stateless hash-based FN-DSA (Falcon) — compact lattice signatures “Harvest now, […]
Quantum-Safe Cryptography Readiness
ML-KEM, ML-DSA, SLH-DSA — what NIST PQC standards mean for 2026 organisations, harvest-now-decrypt-later threat, crypto-agility, hybrid TLS, migration roadmap for Indian banks.
