no-emit-version

# Disable comment string in clear text signatures and ASCII armored messages
no-comments

# Display long key IDs

# keyserver
#-----------------------------

# This is the server that --recv-keys, --send-keys, and --search-keys will
# communicate with to receive keys from, send keys to, and search for keys on
keyserver hkps://hkps.pool.sks-keyservers.net

# Provide a certificate store to override the system default
# Get this from https://sks-keyservers.net/sks-keyservers.netCA.pem

# Set the proxy to use for HTTP and HKP keyservers - default to the standard
# local Tor socks proxy
# It is encouraged to use Tor for improved anonymity. Preferrably use either a
# dedicated SOCKSPort for GnuPG and/or enable IsolateDestPort and
# IsolateDestAddr

# Don't leak DNS, see https://trac.torproject.org/projects/tor/ticket/2846

# When using --refresh-keys, if the key in question has a preferred keyserver
# URL, then disable use of that preferred keyserver to refresh the key from
keyserver-options no-honor-keyserver-url

# When searching for a key with --search-keys, include keys that are marked on
# the keyserver as revoked
