Scouting report

Wrote honeyd, co-designed the bcrypt password hash with David Mazières, and created systrace and privilege separation work in OpenSSH. At Google he led the Safe Browsing malware research that put interstitial warnings in front of drive-by download sites, and co-authored the papers that measured how large that problem actually was.

Curator’s note

bcrypt alone has protected more passwords than most companies have users.
