$encryption_key and all encryption features will be enabled only if the SQLite encryption module is installed. It's a proprietary, costly module. So if it's not present, supplying an encryption key will have absolutely no effect.

Construct will fail if \ backslash is used in the database path,
use / forward slash instead for directory separators.
