Request: Yubikey integration

[emileturcotte]

Greetings,

I'm not sure whether I'm in the right repository for such a request, so please tell me and I will post it somewhere else.

I have a Yubikey which is tied to my public identity and use for a lot of my online accounts - except Protonmail. I am not fond of having to upload my private key into my web client, although I trust your security, and would prefer if the encryption operations could take place inside my Yubikey instead. A neat feature could be to upload my public certificate into Protonmail and associate it with the emails tied to my GPG key. When opening my mailbox or sending an email, the client could prompt my Yubikey for encryption operations.

Without this, my Protonmail keys are different from my public identity ones and this may look as if I am not who I pretend to be when I write emails to people.

Please let me know if this is feasible, underway or else, as this is a big annoyance for me. Thanks a lot.
