@eff Serious question: What are businesses supposed to do? Secrets are hard to keep in large organizations, and they need to authenticate between organizations.

@mcv @eff We've had PGP and SMIME email for ages but hardly anyone bothers...
Since it takes both parties it's blocked by chicken-and-egg problems getting started.
Kind of amazing that it has come to this and still nobody is very serious about solidly authenticating million-dollar scale transactions.
