Can I just add the fingerprint to the end of my email?

I'm using Apple High Sierra Mac Mail. Public key is uploaded.

I would like to make it as easy as possible for anyone to find my public key.

Ideally I'd add a signature to may email as follows:
"This email is signed/encrypted using OpenPGP certificate. To verify, please use this number XYZ12934ED0 at the public key server here: https://somepgpkeyserver.org/verifykey".

Which is a link they can just click.

It's too much to ask grandma/grandpa to do anything else besides clicking on a web link.

Even better is if there is a link at the key server where they can import the public key automatically.

Any solutions?

Thanks, Caesar.

   Hi csamsi,

   welcome to the GPGTools support platform. This is partly covered in the KB-article which explains, why it is still a good idea, to sign outgoing messages.

   This email is signed / encrypted using OpenPGP. To verify the signature, please use the key with fingerprint USE_FULL_FINGERPRINT_HERE
   Find my public key here: https://keys.openpgp.org/YOURKEY"
   

   There is a mechanism to auto-retrieve public keys in order to verify a signature, when the public key is missing on your local keyring. On macOS with GPG Suite find that feature in System Preferences > GPG Suite > Settings > Key Server.

   That would then require no further action on the receiving end to verify the signature and download the key form the verifying key server.

   All the best,
   Steve
