Smartcard Support

I currently have my gpg keys on a yubikey.

Would be nice if snappymail would support using it

That will not work as the browser or server can't read the yubikey, only act on FIDO2

[kaaax0815]

You can't access the keys. But I would be nice to be able to sign/decrypt emails using snappymail using yubikey without having to import the secret key. As the secret key live securely on the security key

For that gnupg must interact with the yubikey.
So snappymail must be running on the same computer where the yubikey is installed and PHP must have access to gnupg.
This is not something that snappymail is designed for.

It's seems there were already people thinking of the idea
openpgpjs/openpgpjs#1111
openpgpjs/openpgpjs#362
FlowCrypt/flowcrypt-browser#964
openpgpjs/openpgpjs#553

But it seems like this isn't possible currently. But may be in the feature

https://github.com/mailvelope/gpgmejs
This communicates with the local gpg agent. So snappymail would only need to integrate with that

Edit: this requires creating a extension. Mailvelope uses this

[the-djmaze]

Correct. Like i said it is currently hardly to not possible.
