+Key Identity
+============
+
+Salt provides commands to validate the identity of your Salt master
+and Salt minions before the initial key exchange. Validating key identity helps
+avoid inadvertently connecting to the wrong Salt master, and helps prevent
+a potential MiTM attack when establishing the initial connection.
+
+Master Key Fingerprint
+----------------------
+
+Print the master key fingerprint by running the following command on the Salt master:
+
+.. code-block:: bash
+
+   salt-key -F master
+
+Copy the ``master.pub`` fingerprint from the *Local Keys* section, and then set this value
+as the :conf_minion:`master_finger` in the minion configuration file. Save the configuration
+file and then restart the Salt minion.
+
+Minion Key Fingerprint
+----------------------
+
+Run the following command on each Salt minion to view the minion key fingerprint:
+
+.. code-block:: bash
+
+   salt-call --local key.finger
+
+Compare this value to the value that is displayed when you run the
+``salt-key --finger <MINION_ID>`` command on the Salt master.
