In the resulting text, find your key ID in the statement that resembles 'pub 1024D/1B2AFA1C'. Your key ID is the 8 character 'word' after the slash (/). In the previous example, the GPG Key ID is 1B2AFA1C. Write down your key ID.
Export your public key to a public server so that others can find it with the following command, substituting your key ID:
gpg --keyserver subkeys.pgp.net --send-keys GPGKEYID
