Key derivation functions

ID: key-derivation-functions

Key Derivation Functions (KDFs) are cryptographic algorithms designed to derive one or more cryptographic keys from a secret value, such as a password, a master key, or a seed. The main purpose of a KDF is to take an input (often low-entropy data) and transform it into a higher-entropy key suitable for use in cryptographic applications, such as encryption, signing, or secure communications.
