Hi again!
I'm slowly rebooting my Autocrypt/Mailpile efforts, after a
too-long hiatus. I was reviewing the spec with one of my
collaborators, and we ended up with differing interpretations of
what to do if an Autocrypt header is missing. It appears the
internal state management section got over-simplified to the
point that it is no longer explicitly clear on this.
On the one hand, the "Internal State Storage" section says:
> For example, if a remote peer disables Autocrypt or drops back
> to only using a non-Autocrypt MUA, we must stop sending encrypted
> mails to this peer automatically.
On the other, the section on "Updating Autocrypt Peer State" says
this:
> 3. If the Autocrypt header is unavailable, no further changes are required and
> the update process terminates.
... which in the context it is written, implies that no changes to internal state are made. So the lack of an Autocrypt header is no longer a reset.
Which interpretation is correct? Do we no longer have resets?
Thanks!
