magento2 – How to verify an encrypted module admin configuration from my database?

When a module configuration is saved in an encrypted mode I just see dots in the admin panel, as the image below shows.

How to verify an encrypted module admin configuration from Magento 2 Database

When I check in the database via Magerun the result is that below.

n98-magerun2 config:store:get narvar_accord/narvar_settings/narvar_auth
+-------------------------------------------+---------+----------+------------------------------------------------------------------------------+
| Path                                      | Scope   | Scope-ID | Value                                                                        |
+-------------------------------------------+---------+----------+------------------------------------------------------------------------------+
| narvar_accord/narvar_settings/narvar_auth | default | 0        | UmFmYWVsIENvcnJlYSBHb21lcwo= |
+-------------------------------------------+---------+----------+------------------------------------------------------------------------------+

When I run the same command with the –decrypt parameter, the value is unreadable.

+-------------------------------------------+---------+----------+----------------------------------------------------------+
| Path                                      | Scope   | Scope-ID | Value                                                    |
+-------------------------------------------+---------+----------+----------------------------------------------------------+
| narvar_accord/narvar_settings/narvar_auth | default | 0        | և�2��ڢ�[ |
+-------------------------------------------+---------+----------+----------------------------------------------------------+

How could I see the decrypted value for that configuration?
