Current setup with database:
One database: servers.db
Five tables:
-----------------------
certificates
servers
wifi_servers
mobile_servers
bluetooth_servers
-----------------------
Table certificates is for certificates
Table servers is for server_id and common properties
and it's certificate_id is a foreign key referencing the id in certificates
Then the other tables include server type specific data
and their id is a foreign key referencing the id in table servers
Example:
sqlite> SELECT * FROM certificates;
_id _certificate _fingerprint
---------- ------------ ----------------------------------------------------------------
1 BLOB b7b4fe3fc6b3105d8abbc4ec28c4de27de200dba64c01f71ef9e03d835bcb1ad
2 BLOB 152a37c15304eb14cece3558a2e7a442bc1be58374eac45c6b1fb390a91cffd1
sqlite> SELECT * FROM servers;
_id _is_enabled _certificate_id
---------- ----------- ---------------
1 1 1
2 0 2
3 1 2
sqlite> SELECT * FROM wifi_servers;
_id _ip_or_hostname _port _ssid_whitelist
---------- --------------- ---------- ---------------
1 192.168.15.40 31337 Wifi22
sqlite> SELECT * FROM mobile_servers;
_id _ip_or_hostname _port _roaming_allowed
---------- --------------- ---------- ----------------
2 mobile.com 44325 0
sqlite> SELECT * FROM bluetooth_servers;
