Unlock database by scanning a QR code

I am currently using a keyfile whose text exceeds 200 characters.

However, that keyfile I need to hide it somewhere in the smartphone directories.

Turning that keyfile (basically a .txt file) into a QR code would allow the key to be outside the device. This would increase convenience and security, in my opinion.

Start by locating the keyfile-based database unlock flow in the Android app and the entry point where a keyfile is selected or entered. Determine how a scanned QR value could supply the keyfile content, then verify that a keyfile longer than 200 characters unlocks the database successfully without requiring the text file to remain on the device.
