+tree item. The command line tool is accessed via the ``network`` subcommand.
+These interfaces allow you to carry out some basic network management tasks,
+such as adding, configuring, and removing network interfaces.
+
+.. note:: Any changes made to the network configuration are not
+  applied, until you click on **Apply Configuration** or enter the ``network

+You can also use ``proxmox-backup-client key`` to create an RSA public/private
+key pair, which can be used to store an encrypted version of the symmetric
+backup encryption key alongside each backup and recover it later.
+
+To set up a master key:
+
+1. Create an encryption key for the backup:
+
+   .. code-block:: console
+
+     # proxmox-backup-client key create
+     creating default key at: "~/.config/proxmox-backup/encryption-key.json"
+     Encryption Key Password: **********
+     ...
+
+   The resulting file will be saved to ``~/.config/proxmox-backup/encryption-key.json``.
+
+2. Create an RSA public/private key pair:
+
+   .. code-block:: console
+
+     # proxmox-backup-client key create-master-key
+     Master Key Password: *********
+     ...
+
+   This will create two files in your current directory, ``master-public.pem``
+   and ``master-private.pem``.
+
+3. Import the newly created ``master-public.pem`` public certificate, so that
+   ``proxmox-backup-client`` can find and use it upon backup.
+
+   .. code-block:: console
+
+     # proxmox-backup-client key import-master-pubkey /path/to/master-public.pem
+     Imported public master key to "~/.config/proxmox-backup/master-public.pem"
+
+4. With all these files in place, run a backup job:
+
+   .. code-block:: console
+
+     # proxmox-backup-client backup etc.pxar:/etc
+
+   The key will be stored in your backup, under the name ``rsa-encrypted.key``.
+
+   .. Note:: The ``--keyfile`` parameter can be excluded, if the encryption key
+     is in the default path. If you specified another path upon creation, you
+     must pass the ``--keyfile`` parameter.
+
+5. To test that everything worked, you can restore the key from the backup:
+
+   .. code-block:: console
+
+     # proxmox-backup-client restore /path/to/backup/ rsa-encrypted.key /path/to/target
+
+   .. Note:: You should not need an encryption key to extract this file. However, if
+     a key exists at the default location
+     (``~/.config/proxmox-backup/encryption-key.json``) the program will prompt
+     you for an encryption key password. Simply moving ``encryption-key.json``
+     out of this directory will fix this issue.
+
+6. Then, use the previously generated master key to decrypt the file:
+
+   .. code-block:: console
+
+     # openssl rsautl -decrypt -inkey master-private.pem -in rsa-encrypted.key -out /path/to/target
+     Enter pass phrase for ./master-private.pem: *********
+
+7. The target file will now contain the encryption key information in plain
+   text. The success of this can be confirmed by passing the resulting ``json``
+   file, with the ``--keyfile`` parameter, when decrypting files from the backup.
+
+.. warning:: Without their key, backed up files will be inaccessible. Thus, you should
+  keep keys ordered and in a place that is separate from the contents being
+  backed up. It can happen, for example, that you back up an entire system, using
+  a key on that system. If the system then becomes inaccessable for any reason
+  and needs to be restored, this will not be possible as the encryption key will be
+  lost along with the broken system. In preparation for the worst case scenario,
+  you should consider keeping a paper copy of this key locked away in
+  a safe place.

+//!
+//! * [`Username`]: an owned user name. Internally a `String`.

+//! * [`RealmRef`]: a borrowed realm (`str` equivalent).
+//! * [`Userid`]: an owned user id (`"user@realm"`). Note that this does not have a separate

+//! Note that `Username`s are not unique, therefore they do not implement `Eq` and cannot be
+//! compared directly. If a direct comparison is really required, they can be compared as strings
+//! via the `as_str()` method. [`Realm`]s and [`Userid`]s on the other hand can be compared with
