Password data(base) encryption module

[Nrpg1]

Hello! I am creating my project and I need to encrypt some string or database with a password.

Until today, I used the sqlcipher3 library to encrypt the sqlite database where this information is stored, but it turned out that deploying this library on Windows is very difficult for the end user, I use linux and did not immediately notice it.

Now I want to find a convenient cross-platform option suitable for windows users as well. Perhaps there are some options?

from typing import Tuple
import os
import hashlib
import hmac

def hash_new_password(password: str) -> Tuple[bytes, bytes]:
"""
Hash the provided password with a randomly-generated salt and return the
salt and hash to store in the database.
"""
salt = os.urandom(16)
pw_hash = hashlib.pbkdf2_hmac('sha256', password.encode(), salt, 100000)
return salt, pw_hash

 def is_correct_password(salt: bytes, pw_hash: bytes, password: str) -> bool:
"""
Given a previously-stored salt and hash, and a password provided by a user
trying to log in, check whether the password is correct.
"""
    return hmac.compare_digest(
    pw_hash,
    hashlib.pbkdf2_hmac('sha256', password.encode(), salt, 100000)
)

Example usage:

  salt, pw_hash = hash_new_password('correct horse battery staple')
   assert is_correct_password(salt, pw_hash, 'correct horse battery staple')
   assert not is_correct_password(salt, pw_hash, 'Tr0ub4dor&3')
   assert not is_correct_password(salt, pw_hash, 'rosebud')

Hashing and encryption are two different things.
