## 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:
|
|
|
|
```sh
|
|
sudo qubesctl top.enable sys-pgp
|
|
sudo qubesctl --targets=tpl-sys-pgp,sys-pgp state.apply
|
|
sudo qubesctl top.disable sys-pgp
|
|
sudo qubesctl state.apply sys-pgp.prefs
|
|
```
|
|
|
|
* State:
|
|
|
|
<!-- pkg:begin:post-install -->
|
|
|
|
```sh
|
|
sudo qubesctl state.apply sys-pgp.create
|
|
sudo qubesctl --skip-dom0 --targets=tpl-sys-pgp state.apply sys-pgp.install
|
|
sudo qubesctl --skip-dom0 --targets=sys-pgp state.apply sys-pgp.configure
|
|
sudo qubesctl state.apply sys-pgp.prefs
|
|
```
|
|
|
|
<!-- pkg:end:post-install -->
|
|
|
|
Install on the client template:
|
|
|
|
```sh
|
|
sudo 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:
|
|
|
|
```sh
|
|
qvm-features QUBE service.split-gpg2-client 1
|
|
```
|
|
|
|
## 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:
|
|
|
|
```qrexecpolicy
|
|
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](https://github.com/QubesOS/qubes-app-linux-split-gpg2)
|
|
on how to use split-gpg2.
|
|
|
|
Save your PGP keys to `sys-pgp`, using isolated GnuPG home directory per qube
|
|
at `~/.gnupg/split-gpg/<QUBE>`.
|
|
|
|
On `dom0`, enabled the service `split-gpg2-client` for the client qube `dev`:
|
|
|
|
```sh
|
|
qvm-features dev service.split-gpg2-client 1
|
|
```
|
|
|
|
On the qube `sys-pgp`, generate or import keys for the client qube `dev`:
|
|
|
|
```sh
|
|
mkdir -p -- ~/.gnupg/split-gpg/dev
|
|
gpg --homedir ~/.gnupg/split-gpg/dev --import /path/to/secret.key
|
|
gpg --homedir ~/.gnupg/split-gpg/dev --list-secret-keys
|
|
```
|
|
|
|
On the qube `dev`, import the public part of your key:
|
|
|
|
```sh
|
|
gpg --import /path/to/public.key
|
|
```
