QUESTION
I'm currently in the process of building a password manager as a project to get a better understanding of PostgreSQL, alongside learning how to handle data between Python and a database.
Here's a little about the logic of my password manager.
- If you're a new user, the program will greet you with a prompt awaiting a master password to be set, to access your password vault. Once set, the master password is encrypted using the hashlib Python module as you can see below in the code snippet. A key and a salt is used to encrypt the password, and both are stored as binary values in the database. These values are sent to the databse using the psycopg2 Python module.
- If you're an existing user, the program will greet you with a promt awaiting the already-set master password so you can access with your password vault. The program will fetch the key and salt from the database, use the salt to create a new key and see if the key and new key values match. If they do, access granted, otherwise access denied to the vault.
However, I have encountered the following problem: the binary data (key and salt) that is stored in the database is not the same as the binary data (key and salt) in Python. Below you will find my code:

I'm struggling to get my method working correctly. I've thought about using a lambda
function which I did for another problem and that worked, however here it does not seem to work. I'm trying to change the functions to methods and for some reason, my method is not working correctly since it has no reference to the tree. I've tried using a lambda
function although that does not work.
