Key Derivation

Understand how to use Python's key derivation functions including pbkdf2_hmac, scrypt, and bcrypt to securely hash passwords with salt and iterations. Learn practical examples and best practices to strengthen cryptographic security in your Python applications.

Python has pretty limited support for key derivation built into the standard library. In fact, the only method that hashlib provides is the pbkdf2_hmac method, which is the PKCS#5 password-based key derivation function. It uses HMAC as its pseudorandom function. We might use something like this for hashing our password as it supports salt and iterations. For example, if we have to use SHA-256, we would need a ...
