@ahasty @ati1 @linmob You should be able to use #Thunderbird for #PGP encrypted email (with mobile-config-thunderbird), or webmail instance that supports it like #SnappyMail or any other webmail using #Mailvelope extension in Firefox.

Not sure about #YubiKey, #NitroKey or alternatives as I've never used any, but they should connect to the Librem's USB-C port. The #Librem5 has a slot for a PGP smart card ( #LibremKey ?) to store private keys so you could also use that. Hopefully, someone who's used that can see your question and answer, or you can ask in Purism forums or pmOS Matrix room.

Signal selected Google Gmail as their email provider.

Consider asking for a public PGP encryption key if you are concerned about Google accessing the content of your message, this can provide end-to-end encryption of the message content but the metadata will be available to Google.

Signal: Please publish a key on your website.

@lns Should but they never will, with good reason. They don't really need to, for email encryption at least there's #DeltaChat that non-technical people have a better chance of learning. Yes, it only uses a subset of #PGP called #Autocrypt, but if you really want to use PGP, there are much better tools than #GPG like: #Thunderbird, #Mailvelope and #Kleopatra. I know some of these are front-ends for GPG.

看起來 #mailvelope 對 #pgp #autocrypt 的支援還是不行，我看起來 S/MIME encrypt-subject 也都沒有支援？
官網沒有講得很清楚，但 s/mime 的 issue 開著，官網也直接寫不支援加密主旨。
autocrypt 則是寫有做，但又標沒有 web mail provider 支援， autocrypt.org 也沒有列，不太懂是什麼情況，可能要實際用一次。
如果只是 autocrypt header 沒做，金鑰有發布的話還能靠 mailvelope 自家的 key server 找，但不支援 s/mime 的話 autocrypt 也不可能了。
畢竟 mailvelope 是基於 web-mail ，不能直接讀 header，很多功能做不到。
如果有 mailvelope 使用者歡迎補充。

💌 It’s always a pleasure to have the Mailvelope team joining us at the Passbolt office here in Luxembourg. Mailvelope is an open-source solution that allows you to secure your email with end to end encryption. It works in the browser with existing webmail applications (Gmail, GMX, Nextcloud, etc.). They will be present at Nextcloud enterprise day in Frankfurt next week, don’t be shy, come say hi!
