yescrypt: password hashing scalable beyond bcrypt and scrypt

These are the slides we used at PHDays 2014. In a sense, this presentation is a continuation of Password security: past, present, future (PHDays 2012, Passwords^12), Password hashing at scale (YaC 2012), New developments in password hashing: ROM-port-hard functions (ZeroNights 2012), and it is continued with yescrypt: large-scale password hashing (BSidesLjubljana 2017), so please check those out as well.

Current yescrypt specification and code are available on the Password Hashing Competition (PHC) website, with a summary similar to what's seen on these slides also available on the PHC wiki.

Please click on the slides for higher-resolution versions. You may also download a PDF file with all of the slides (1.4 MB).
