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.
Secret Sharing — Shamir's Scheme
Splitting a secret into N shares where any K can reconstruct it — preventing single points of failure for root encryption keys and disaster recovery credentials.

Symmetric Encryption PHP 7.2+
Encryption where the same key encrypts and decrypts data — fast and suitable for bulk data, but key distribution is the primary challenge.
