The struggle for secure cryptography
summary
Claim: only primitives vetted by an open competition and subjected to wide public analysis earn trust. Concrete evidence: Spritz yields an algorithm that recovers internal state in 2 to the power 12 47 operations; MD5 and SHA‑1 admit collision methods faster than brute force; a proprietary MIFARE contactless card cipher collapses billions of deployed cards. Competitions like AES and SHA‑3 (Keccak) produce designs with many rounds unbroken after years of public cryptanalysis.
