Bio

Author of the reference books Serious Cryptography (No Starch Press, 2017) and Crypto Dictionary (No Starch Press, 2020). Designed the ubiquitous crypto algorithms BLAKE2 and SipHash. Speaker at leading information security conferences (Black Hat, DEF CON, Real World Crypto, etc.). Journalists have described me as a ''luminary'', ''well-regarded expert in crypt analysis''​ (sic), and ''a classic cryptographer and quite an understandable of the sort''. Oh well :)
