yescrypt: large-scale password hashing

In this presentation, the problem of password hash cracking is framed as largely that of cost amortization, and thus the problem of password hashing as coming up with affordably costly and amortization-resistant password hashing schemes. In this context, rationale is given for both scrypt's sequential memory-hard hashing and yescrypt's numerous additions to it. Finally, application of yescrypt to mass user authentication is demonstrated.
