Pyqt | Password storage software?

Question

Python

I'm thinking of making a program for storing passwords in PyQt.
I see it this way. Python tries to open a secure database file, a dialog box pops up, the user enters a master password, after which the database with passwords is loaded into the GUI.
Is it realistic to do so? How can the database be encrypted and in what format will it be?
Ready-made services, please do not offer.

Answer 1

SQLite + one of its encryption extensions .
