Existing open source project

The problem with Dashlane, LastPass etc. is, that they offer a good service but you give your passwords at the hand of a company which might have backdoors. Arcanum is a project of mine to circumvent that. By encrypting passwords and storing them in a personal database. Due to all the code being open source everything is in controll of the user. Currently password management is nearly complete. Additional features like asymmetric encryption, key management and secure notes are planned. The project uses purely Python with PyQt for the GUI and python-gnupg for encryption. Im asking for help to get some ppl with more experience on the security side as I am not an expert in this field. Also due to me only having the weekends to do some small additions any help is really apreciated.

Python, Pyqt, PGP, SQL
