Telling other about your public key
As we know, it might be hard for people to not use mails and other government-controlled social medias to send others a public key. The key might get deleated or censored.
So here we have our “keyserver”, they are not government-censored and is used by all, examples are http://keyserver.ubuntu.com/ or https://keys.openpgp.org/, this could be amazing to send all your keys through an uncensored way.
you should export you public key in bash using
gpg --export -a -o public.key [KEYID]
