Please encrypt your email, if you can. This is a way to send me encrypted mail without having access to dedicated tools since it works in your browser, instead. Let me know how I can reply to you via Threema, or Signal, in your message!
If you encrypt your mail to email@example.com, your program should automatically retrieve the key from my domain using the Web Key Directory protocol (WKD). Alternatively, you can also get it from the keys.openpgp.org keyserver. Let me know where I can get your public key, in your message!
I wrote a Gmail, Gnus and GPG Guide, if you’re an Emacs user.
