To password-protect and encrypt the data in the database zip file, use the File > Protect command and specify a password consisting of at least 6 characters.

To encrypt the data, GS-Base currently uses the Twofish CFB algorithm. All encryption parameters are saved in the META-INF/manifest.txt text stream in the database zip file.

If the database zip file is encrypted and you still want to manipulate some of its data manually without GS-Base, using Windows Explorer, you must not alter the META-INF/manifest.txt file in any way, or you'll risk losing the data.

Files added by users manually to the zip that are not used/imported by GS-Base remain unencrypted and are moved to the unused/ zip subfolder.

If a database is encrypted and protected, there is a green shield symbol displayed on the status bar.

Regardless of the above file-level protection, you can still use individual field encryption in tables.
