@nicfab @Fr333k Just an observation: that's a long blog post, with a lot of words and with a lot of computer commands and that somewhat contradicts the sentence "WKD makes encrypted email as simple as HTTPS made web browsing secure."
Nothing is simple with OpenPGP and email and that's broadly documented in academia and annecdotes. WKD does not change that.
If you absolutely positively must use email for sending sensitive info, use S/MIME.
