Hi all,

I've minted a new version of draft-ietf-openpgp-persistent-symmetric-keys,
since it had been a while and the last one expired.

It has one substantive change: creating or using persistent symmetric
keys with an algorithm weaker than AES-128 is now disallowed.
(Doing so was obviously a bad idea anyway but it seemed like a good
idea to spell that out.)

Additionally, it contains a number of editorial improvements and
clarifications, thanks to dkg and Heiko.

It does not yet address the question of how to deal with certifications
and revocations, raised on the list and in the issue tracker. Thanks to
everyone who weighed in on that already, I will also do so (without
editor hat on) after this, and then I hope we can discuss and perhaps
make a decision at the interim meeting.

In the meantime, please also let me know whether the editorial points
seem sufficiently resolved or if any further clarifications are needed.

Thanks!

Best,
Daniel

> 
>    This document defines a new packet and algorithm for the OpenPGP
>    standard (RFC 9580) to support persistent symmetric keys, for message
>    encryption using authenticated encryption with additional data (AEAD)
>    and for message authentication using AEAD authentication tags.  This
>    enables the use of symmetric cryptography for data storage (and other
>    contexts that do not require asymmetric cryptography), for improved
>    performance, smaller keys, and improved resistance to quantum
>    computing.
