# The default key to sign with. If this option is not used, the default key is

# Uncomment the following option to get rid of the copyright notice
no-greeting

# create ASCII armored output (default is binary OpenPGP format)
#armor

# If you do not use the Latin-1 (ISO-8859-1) charset, you should tell
# GnuPG which is the native character set.  Please check the man page
# for supported character sets.  This character set is only used for
# metadata and not for the actual message which does not undergo any
# translation.  Note that future version of GnuPG will change to UTF-8
# as default character set.
charset utf-8

# Disable inclusion of the version string in ASCII armored output
no-emit-version

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

# Display long key IDs
keyid-format 0xlong

# List all keys (or the specified ones) along with their fingerprints
with-fingerprint

# Also list the "keygrip", which is the ID used by `gpg-agent`.
# (GnuPG >=2.1)
with-keygrip

# Display the calculated validity of user IDs during key listings

# Try to use the GnuPG-Agent. With this option, GnuPG first tries to connect to
# the agent before it asks for a passphrase.

# 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 hkp://pool.sks-keyservers.net
#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
# option 'ca-cert-file' is obsolete. (GnuPG >= 2.1)
#keyserver-options ca-cert-file=~/dotfiles/.gnupg/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
#keyserver-options http-proxy=socks5-hostname://127.0.0.1:9050
# Don't leak DNS, see https://trac.torproject.org/projects/tor/ticket/2846
# XXX: unknown to gnupg 2.1.7
#keyserver-options no-try-dns-srv

# 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
keyserver-options include-revoked

# Automatic retrieve keys from a keyserver when verifying signatures made by
# keys that are not on the local keyring.
# NOTE: This option makes a "web bug" like behavior possible.
#       Keyserver operators can see which keys you rquest, so by sending
#       you a message signed by a brand new key (which you naturally will
#       not have on your local keyring), the operator can tell both your
#       IP address and the time when you verified the signature.
