Daniel J. Bernstein is the designer of the “tinydns” software used by Facebook to publish server addresses, the “ChaCha20” cipher used to encrypt Chrome’s HTTPS connections to Google, the “dnscache” software used by OpenDNS to handle address requests from 65 million Internet users, the “SipHash” hash function (co-designed with Jean-Philippe Aumasson) used by Python to protect against hash-flooding attacks, the “qmail” software used by Yahoo to receive mail, and the “Curve25519” public-key system used by WhatsApp for end-to-end encryption.
