hide your PGP version & other info

# Hide your PGP version & other PGP version metadata with these two config lines.

# This line hides the "Version: GnuPG vX.XX.XX" line
no-emit-version

# This line hides the "Comment: XXXXX" lines
no-comments
# NOTE if you are using Thunderbird+Enigmail you probably need to set this again in
# the Enigmail->Preference settings:

# Some notes:
#
# If you're super paranoid, you might want to check out what TAILS
# uses too. Longer key ID display, stronger crypto prefs, etc.
# (But note that some of the config is Tor-specific.)

# NOTE that when using Mac Mail (GPGTools) -- which sends by PGP/MIME by default
# instead of a scary plaintext BEGIN PGP SIGNED MESSAGE block -- you'll probably
# leak that you're using GPGTools anyway, because the MIME header says it was generated
# with GPGTools.
#
# And of course, your mail client is probably identifying itself and putting its version
# in the e-mail headers. TorBirdy https://addons.mozilla.org/en-us/thunderbird/addon/torbirdy/
# for Thunderbird at least attempts to hide what version of Thunderbird you have, what time zone
# you're in, etc. Your mileage may vary.
