How SHA-2 and SHA-3 Would Break: Merkle-Damgard Collisions, Length Extension, and the Sponge's Algebraic Frontier
SHA-2 and SHA-3 have never broken, yet each construction already dictates how it would fall -- collisions, length extension, and the sponge algebraic frontier.

How the Hash Functions Broke in Real Life: MD5, Flame, SHATTERED, and the Long Death of SHA-1
MD5 and SHA-1 were genuinely, mathematically broken -- yet every real breach still needed a second failure: a deployment still trusting the dead hash.

The Fingerprint Two Files Shared: A Field Guide to Cryptographic Hashes
A field guide to cryptographic hashes: the one promise behind SHA-2, SHA-3, and BLAKE3, why MD5 and SHA-1 died, and how to choose one that keeps its promise.
