So I'm relatively familiar with PGP and have successfully sent and received messages. My questions about if I can delete the part of my PGP key saying the software version and if that affects anything. For example, my key looks like this:
-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: GnuPG/MacGPG2 v2.0.22 (Darwin)
Comment: GPGTools - https://gpgtools.org
UotP8JjdKo8
...............
UotP8JjdKo8
-----END PGP PUBLIC KEY BLOCK-----
Can I delete the lines starting with "Version: ..." and "Comment:..."?

Add the following lines to your "gpg.conf" file:
