No worries. We'll implement https://autocrypt2.org which additionally offers reliable deletion / forward secrecy during 2026 🙂

We are working with Proton cryptographers on OpenPGP specifications, and they are now moving towards using @rpgp , the end-to-end encryption we are using.

Everything will be based on RFC9580 ( v6) ... the eocsystem is moving 🙂

I'm aware of at least 7 serious independent codebases that implement RFC 9580, and almost as many mature implementations of draft-ietf-openpgp-pqc.

Adding autocrypt2 to the mix is a very small additional layer on top of these already widely available building blocks.

(And sure, GnuPG is doing its own thing. But that is really not very relevant to Delta Chat or its users.)

See https://www.ietf.org/archive/id/draft-autocrypt-openpgp-v2-cert-01.html#name-identifying-an-autocrypt-v2 -- in any case, this is exceeding what should be discussed here. Feel free to open an issue on https://codeberg.org/autocrypt2/autocrypt-v2-cert

That doesn't sound very interoperable to me. So a recipient would have to support Autocrypt2 and RFC-9580 (as opposed to LibrePGP). How likely is it that anything else will support that particular combination of standards?

search engines don't find it because they deleted that blogpost. sadly the internet doesn't forget.

I'm genuinely interested (concerned)

But we were implicitly talking about standards/specs based developments and interoperable solutions.

with all of my criticism of @Tutanota (mainly though not exclusively about the time they partnered with one of the main suppliers of the mecha-Hitler AI), i must say they beat both of you to the punch by two years:
