Ben Grande b52e4b1b63 fix: strict split-gpg2 service 
Split-gpg V1 allowed for querying public keys, but as split-gpg2 is
running as an agent, public keys are not queried. Allowing connection to
the server to query only public parts of the key exposes the server more
than needed to the client.

All clients now have to hold the public key they need locally in order
to do GPG operations.

sys-pgp

PGP operations through Qrexec in Qubes OS.

Table of Contents

Description

Creates a PGP key holder named "sys-pgp", it will be the default target for split-gpg and split-gpg2 calls for all qubes. Keys are stored in "sys-pgp", and access to them is made from the client through Qrexec.

Installation

  • Top:
qubesctl top.enable sys-pgp
qubesctl --targets=tpl-sys-pgp,sys-pgp state.apply
qubesctl top.disable sys-pgp
  • State:
qubesctl state.apply sys-pgp.create
qubesctl --skip-dom0 --targets=tpl-sys-pgp state.apply sys-pgp.install
qubesctl --skip-dom0 --targets=sys-pgp state.apply sys-pgp.configure

Install on the client template:

qubesctl --skip-dom0 --targets=tpl-qubes-builder,tpl-dev state.apply sys-pgp.install-client

The client qube requires the split GPG client service to be enabled:

qvm-features QUBE service.split-gpg2-client

Access Control

Default policy: any qube can ask via the @default target if you allow it to use split-gpg in sys-pgp.

Allow the work qubes to access sys-pgp, but not other qubes:

qubes.Gpg2 * work   sys-pgp  ask default_target=sys-pgp
qubes.Gpg2 * work   @default ask target=sys-pgp default_target=sys-pgp
qubes.Gpg2 * @anyvm @anyvm   deny

Usage

Consult upstream documentation on how to use split-gpg.
