Traits which describe the functionality of [key derivation functions].

## About

Key Derivation Functions (KDFs) are cryptographic algorithms that can be used to derive one or more secret keys from
a secret value such as a base derivation key, output of a key-exchange algorithm, or in the case of specially designed
password-based key derivation functions: a password.

KDFs can be used to stretch shorter input keys into longer keys or to obtain multiple keys from a single input. They can
also be used to transform non-uniform secret values, like the output of a Diffie-Hellman exchange, into uniformly random
secrets suitable for use as keys for symmetric cryptographic algorithms (e.g. AES, ChaCha20).
