Mailspring: GPG and S/MIME Plugin

[namnamir]

Dear folks,
I use Ubuntu 18 and like to have GPG - S/MIME or even PGP on it. I have read #25 but it doesn't work for me. It says that it needs a .json file.

What I have done so far:

1. download the introduced plugin from https://keybase.io/kbpgp_public/releases/kbpgp-2.0.8-signed-release.zip
2. unpack it and try to import it in Mainspring menu (Developer > Install Plugin). I get this error:

The plugin or theme folder you selected doesn't contain a package.json file, or it was invalid JSON. Error: Cannot find module '/home/xxxxxx/Downloads/kbpgp-2.0.8-signed-release/kbpgp/package.json'

1. try to create a plugin through the menu but don't know where to put the single .js file I have.

Any idea?

I tried to use the old plugin for nylas in mailspring.
It says the plugin is not been upgraded. So i Followed the guidelines from the article http://support.getmailspring.com/hc/en-us/articles/115001918391. But still after that the same error appears that the plugin is not compatible.

Could not install plugin The plugin or theme you selected has not been upgraded to support Mailspring. If you're the developer, update the package.json's engines field to include "mailspring".

Any news about this?

I need to sign my mails and it does not seems to be possible right now, or is it? (KDE Neon 18.04 and WIN 10)

Seconded. I've tried a number of possible work around in previous issues but not had any luck. Devs is there any sign of light at the end of the tunnel here?

Any news about this? I need to sign my emails to switch to use Mailspring.

So with using ProtonMail and the new Linux encryption bridge (beta!), encryption should work without Mailspring needing to implement anything. Should also be more secure, as the encryption then is done by pros, instead of every application needing an own implementation. I’ll see if I can check this tomorrow or so… 😄

I'd second the request for S/MIME signing and encryption as well as my employer uses S/MIME certificates and I need to be able to at least sign my emails.

// Edit: I should have read the roadmap for Mailspring more thoroughly, though. It seems that signing emails is a planned feature for the coming spring.

The European Directive 2016/943 on the protection of trade secrets requires indirect e-mail encryption. Especially S/MIME is required in this context as an industry standard and is indeed supported by almost all e-mail clients, including the mobile variants.

In our company, the use of S/MIME is currently being discussed and is expected to become mandatory for all employees in the coming weeks. Which will eventually lead to my being unable to use Mailspring any longer. :-(

I can't believe that you sell this as a product without such basic yet important feature.

I’d pay for the pro version just to have this.

I just discovered mailspring and yes this software is a killer app but lack of s/mime avoid me to use it for work. I saw it is on the roadmap, i hope it will be released because mailspring is so really better than Outlook (easy) but also Thunderbird and all others IMHO

hi .. any update on this plugin ?

[bengotow]

Merging into #25 so we can track development of this in one place!

I agree, mailspring looks very promising. Unfortunately without PGP I have to get back to Thunderbird :(
