Cryptography terms
The mathematics keeping secrets in an adversarial world
Cryptography is the foundation of secure communication, authentication, and data integrity across the internet. This category covers symmetric and asymmetric encryption, hashing, digital signatures, TLS, key exchange protocols, and the common mistakes developers make when implementing or misapplying cryptographic primitives. Use libraries — but understand what they are doing.
Post-Quantum Cryptography
CRYSTALS-Kyber (ML-KEM) and CRYSTALS-Dilithium (ML-DSA) standardised by NIST in 2024 — designed to resist attacks from quantum computers.
