This is a simple password hashing PBKDF2 / SCRYPT / ARGON2 Python Implementation for educational purposes only, and it has been used by my computer science undergrad students.
It also executes a basic password strength test (not fancy at all, a pretty basic one).
Not suitable for production in terms of SQL database query sanitization/optimization/auth. The only goal is to demonstrate password hashing implementation instead of a clear text implementation or even a 'pure hash' storage. There's no documentation within the code.
