The life-changing magic of WKD

@Sandra

By the way, if I have someone’s elses public key (recieved,
perhaps, through a WKD request on another computer), can I
construct a faux .vcf file for them and import them that way?

There is a webxdc app that does it: webxdc apps (r10s/asc-to-vcard: Create VCards from classic PGP .asc public key files. - Codeberg.org)

It was mentioned above:

@Minim

Sending VCards is not obvious in the UI but actually easy. See also r10’s “.asc to VCard” app.

@Sandra

Actually if the .vcf solution does work, that solution would be
perfectly satisfactory to me would be an external
.vcf-conversion/import self-hostable app, site, or bot.

There is also a bot that looks up keys on keyserver and WKDs by email address and sends back vCards:
