[dispatch] Opportunistic encryption for email with pEp / Request for feedback

[Bernie Hoeneisen <[e-mail]>]

Dear dispatch list

After an introduction in Prague 
<https://datatracker.ietf.org/doc/minutes-99-dispatch/>, a successful 
BarBoF in Singapore and many hallway discussions we learned that there is 
considerable interest for secure interpersonal messaging, which is at the 
same time also usable and interoperable with systems already deployed out 
in the wild. The main concept of the pretty Easy privacy (pEp) work has 
already been published as I-D:

     https://tools.ietf.org/html/draft-birk-pep


Basically it is about enhanced opportunistic encryption in email (and 
other messaging). We are seeking more feedback on our existing work as 
well to find the right venue (and scope) for this work to continue in the 
IETF.

In addtion to the main draft, we are working on the following topics (to 
be published as I-Ds shortly), whose early drafts your may access already:

- New privacy-enhancing formats for email based upon already existing
   standards, e.g. PGP/MIME (minimizing unnecessarily exposed meta data,
   including encrypting the subject):
   https://pep.foundation/dev/repos/internet-drafts/file/tip/pep-email/draft-birk-pep-email-NN.txt

- Rating System and Privacy Status to label secure / private types of
   communications:
   https://pep.foundation/dev/repos/internet-drafts/file/tip/pep-rating/draft-birk-pep-rating-NN.txt

- Trustwords (similar to the PGP wordlist or RFC 2289) to make
   authenticated communications easy for end-users:

What do you think of this work? If this work is interestig to you, 
we kindly ask you to express your opinion on this list.

Looking forward to your feedback!

Best,
