2.7 Recovery from Lost Master Key

If you accidentally delete or replace the sgtech_config.json file, then the master key is lost and the Spatial Studio application will throw an error.

The sgtech_config.json file includes a master seed property which contains the master key value that enables decryption of encrypted items such as database passwords. It is therefore recommended to backup your sgtech_config.json file in a safe location.

However, if you lose the sgtech_config.json file, then it is possible to recover from a lost master key by performing the following steps:

1. Stop the Spatial Studio instance by running the following command from the application installation directory:

   ./stop.sh

   If you installed the application from the Cloud Marketplace, then use the following command:

   sudo systemctl stop spatialstudio

2. Run the following command in your Spatial Studio repository using a SQL client (such as Database Actions, SQL Plus or SQL Developer):

   DELETE
       "SGTECH_OBJECT"
   WHERE
       "TENANTID" = 'GLOBAL'
       AND (
           "ID" IN ('id__sgtech.safe_text.magicword', 'id__sgtech.key_pair.rsa')
           OR "OBJECTTYPE" = 'access_token'
       );
   COMMIT;

3. Start Spatial Studio by running the following command from the application installation directory:

   ./start.sh

   If you installed the application from the Cloud Marketplace, then use the following command:

   sudo systemctl start spatialstudio

4. Log into Spatial Studio as the admin user.
5. Navigate to the Connections page.
6. Right-click on each connection, select Edit, and re-enter the password for each connection.
7. Open Access Tokens dialog and delete each active token.
8. Navigate to the Console page.
9. Optionally, if you had created a custom basemap with a separate API key, then re-enter the API Key by editing the required custom basemap.
   Click Basemaps under Settings to view and edit your custom basemap.
10. Optionally, if you had created a Cesium basemap with a separate API key, then re-enter the API Key by editing the required Cesium basemap.
    Click Cesium Basemaps under Settings to view and edit your Cesium basemap.

Make sure to back up the sgtech_config.json configuration file safely this time so you do not have to repeat this process in the future.
