Mailspring: [Feature Request] Allow emails to be signed with a certificate / private key

[icf20]

hello i am interested in this feature ( nylas dint have it) that allow to sign email with a government issues certificate signed by a root certificate(like this one https://www.sede.fnmt.gob.es/descargas/certificados-raiz-de-la-fnmt) for business representative.

are there any plans for something like this ?

Hey @icf20 — I actually hadn't heard of this but I think this would be a great feature.

Could you do me a favor and (if you can), send me an example of a signed email to [email protected]? That will help me understand exactly what the end result should look like and I can investigate adding it in the future.

Also, does the government or business provide any sort of tutorial or instructions for setting this up in your current client? I'd also be interested in seeing that, since I'd want to make Mailspring consistent with what you're already doing. Thanks!

Looking at https://www.nylas.com/blog/pgp/ Nylas used to support PGP, but Mailspring keeps adding these to the config.json any time I change a line:

    "disabledPackages": [
        "message-view-on-github",
        "personal-level-indicators",
        "phishing-detection",
        "nylas-private-salesforce",
        "github-contact-card",
        "keybase",
        "composer-markdown",
        "composer-scheduler",
        "composer-mail-merge",
        "send-and-archive",
        "main-calendar"
      ]

@bengotow Any news on this?

I also need pki S/MIME signing, which is what I think this request is about. I'd love to move off of Thunderbird, but this is a must have feature. :/

Edit:
Note, this isn't pgp or gpg. This is certificate signing/encryption.

Pretty unuseful a email client without digital sign inserting capacity!

[beowuff]

I've actually moved on from Thunderbird to kmail. Yep. Even kmail supports both pgp and pki certificate signing.

same here, I can't move from thunderbird without this feature.

any progress on this?

Any progress on the "digital signing" feature. Otherwise not worth it for me moving from thunderbird, or even pay for the pro features.

This feature is the only one that keeps me from moving away from Thunderbird. Any news?

This is the only feature that keeps me from using Mailspring for my email client needs. Please consider implementing this even if there's a nominal fee! Thanks!

Would love this feature too! Interested in setting up my own email hosting off my own domain and adding signing and encryption to my emails to improve trust to my messages. :)
