Support functions involving cryptography.

cardinal_pythonlib.crypto.hash_password(plaintextpw: str, log_rounds: int = 12) → str[source]

Makes a hashed password (using a new salt) using bcrypt.

The hashed password includes the salt at its start, so no need to store a separate salt.

cardinal_pythonlib.crypto.is_password_valid(plaintextpw: str, storedhash: str) → bool[source]

Checks if a plaintext password matches a stored hash.

Uses bcrypt. The stored hash includes its own incorporated salt.
