Note 1: it is also possible to create a dedicated user to store the PGP public keys
|
|
||||||
|
|
||||||
1) useradd -s /bin/false -d /var/gpg -M gpgmap
|
## Note 1
|
||||||
2) mkdir -p /var/gpg/.gnupg
|
|
||||||
3) chown -R gpgmap /var/gpg
|
It is possible to create a dedicated user to store the PGP public keys with
|
||||||
4) chmod 700 /var/gpg/.gnupg
|
these example commands:
|
||||||
5) sudo -u gpgmap /usr/bin/gpg --import /home/youruser/public.key --homedir=/var/gpg/.gnupg
|
|
||||||
a) replace the path with the location of your public key
|
useradd -s /bin/false -d /var/gpg -M gpgmap
|
||||||
b) the path can be deleted after importation
|
mkdir -p /var/gpg/.gnupg
|
||||||
6) Confirm that it's working: sudo -u gpgmap /usr/bin/gpg --list-keys --homedir=/var/gpg/.gnupg
|
chown -R gpgmap /var/gpg
|
||||||
7) Use keyhome = /var/gpg/.gnupg in gpg-mailgate.conf
|
chmod 700 /var/gpg/.gnupg
|
||||||
|
sudo -u gpgmap /usr/bin/gpg --import /home/youruser/public.key --homedir=/var/gpg/.gnupg
|
||||||
|
|
||||||
|
- Replace `/home/youruser/public.key` with the location of your public key
|
||||||
|
- `/home/youruser/public.key` can be deleted after importation
|
||||||
|
- Confirm that it's working: `sudo -u gpgmap /usr/bin/gpg --list-keys --homedir=/var/gpg/.gnupg`
|
||||||
|
- Use `keyhome = /var/gpg/.gnupg` in `gpg-mailgate.conf`
