It might sound like a real nit, but " An updated public-key fingerprint
mechanism"

OpenPGP fingerprints are created using message digests. And distributions
of the code inevitably involve fingerprints of code, not just keys.

Would prefer it just say "An updated fingerprint mechanism"


One of the things I have been working on recently involves fingerprints of
symmetric keys which I describe on the right key list. The approach is
powerful and I believe it is likely to be useful for a range of personal
pki apps.

The thing that has been a killer in the past is management of personal
private keys. The problem is getting worse as we have five platforms
instead of just one. In 1992 I only had a desktop. Now I have desktops,
laptops, tablets, phones and a watch. And only the last one of those is
singular. This is a problem that is clearly linked to OpenPGP and should be
served by any solution. But any solution has to support any application
requiring credential management.
