neutron VS openpgpjs

PS: I hope that we selfhosters will have a modern, efficient, easy to use mail suite one day with modern features like JMAP, good self-learning spam integration, automated checks and validations for SPF/DMARC/DKIM or whether the IP/host suddenly appears in a blocklist and integrated encryption at rest for emails. Something that isn't 30 services in a container image, with 30 different configuration styles. Maybe even with an API integrated that's compatible to the ProtonMail frontend (like the neutron server once intended to be). Anyway, I'm sorry for dreaming. ;)

A bit related: there was a FOSS backend once but I don't think anyone wants to push further.

Some folks once started neutron which is an email server that can be used with the FOSS Protonmail web client but it was abandoned. And I guess you'd want to support JMAP in addition to IMAP as well apart from having automated encryption of incoming plain-text emails.

Anyway, to the topic: there was once neutron which is a server that aimed at ProtonMail compatibility. So that'd would simply would be able to use the same open source frontend from ProtonMail. However, this was abandoned. So you, or somebody else, could revive it.

Some folks also started implementing an FOSS ProtonMail but this project was abandoned at some point. But maybe someone will fork and revive it one day.

Two devs once started implementing a free ProtonMail server but they abandoned it. It's understandable, since it's a lot of work.

Some folks once started a free implementation of the Protonmail backend in Go. Maybe you want to revive it?

Some folks also started an open source Protonmail backend but this was abandoned at one point.

not a great example, in the FOSS side of things GnuPG is being constantly worked on as is openpgp.js

https://openpgpjs.org/

A number of Chrome (and I think also Firefox) extensions include their own local copy of OoenPGP.js for use with various webmail services, including GMail.

WKD (and HKP) depends upon HTTPS without cert pinning, FWIU: https://wiki.gnupg.org/WKD

  How does an email client use WKD?

I know this might not be the appropriate sub, but does anyone know if there are any good learning resources on this? I am struggling to implement an OpenPGP application using Java, and the documentation is no help. I have had great luck with https://openpgpjs.org/ (a very well documented resource), but I don't understand how to accomplish generating keys, storing them in armored files, and using the stored keys for signing and encryption with BouncyCastle. Any pointers would be greatly appreciated.

I used openpgpjs to do all the encryption and decryption. It works perfectly in the browser and nodejs, but not in react native :(

What's your opinion of OpenPGPJs? Do you think JavaScript is just too insecure for it to be safe?

a) We use an open source cryptographic library, OpenPGPjs, which is built by the good folks over at Protonmail, and the library itself is frequently audited. Here's one. And everything you see and use on Cryptee is built on top of this.
