Hi folks,

After our presentation in Prague and an adoption call on this mailing list,
I'm happy to say that we have posted draft-irtf-cfrg-hpke-00.

This version has a couple of notable changes from the last individual draft:

- The "setup" logic across the various modes has been united into a single
algorithm
- As a result, we added a "PSK + Auth" mode, where the sender is
authenticated to hold both a PSK and an asymmetric key
- Instead of one monolithic ciphersuite, individual algorithms are signaled
independently

In addition, there were a bunch of clarifications and bugfixes thanks to
Dave Cridland.

We've asked the chairs for some time to discuss this draft in Montreal, so
please take a look and let us know what you think!

Thanks,
--Richard
