Database Changes

The requirements for Guard 2.0 are less than 1.2, as each encrypted item does not take up a database entry.

Storage requirements are essentially just the keys

New tables created for uploaded PGP keys

New table for PGP Public key lookup created in the main Guard database. This is used to locate public
keys based on their fingerprint.

In order to add the additional database tables and update the lookup table, an upgrade process is required. Instructions here
