# Usage:
# You need to create a secret keyring (secring.gpg). You can use your
# existing one, or create a new one by doing something like the
# following:
# $ GNUPGHOME=/src/debian/mini-dinstall/s3kr1t gnupg --gen-key
set -e
# User variables
# MAKE SURE TO MAKE THIS DIRECTORY 0700!
export GNUPGHOME=/src/debian/mini-dinstall/s3kr1t
if [ ! -d "$GNUPGHOME" ]; then
mkdir -p "$GNUPGHOME"
fi
if [ -z "$USER" ]; then
USER=$(id -n -u)
fi
# This is just a default value
KEYID=$(getent passwd $USER | cut -f 5 -d : | cut -f 1 -d ,)
PASSPHRASE=$(cat "$GNUPGHOME/passphrase")
# These should fail if for some reason the directory isn't owned by us
chown "$USER" "$GNUPGHOME"
chmod 0700 "$GNUPGHOME"
# Initialize GPG
gpg --help 1>/dev/null 2>&1 || true
rm -f Release.gpg.tmp
echo "$PASSPHRASE" | gpg --no-tty --batch --passphrase-fd=0 --default-key "$KEYID" --detach-sign -o Release.gpg.tmp "$1"
mv Release.gpg.tmp Release.gpg
