Key Derivation FunctionsΒΆ
This module contains a collection of standard key derivation functions.
A key derivation function derives one or more secondary secret keys from one primary secret (a master key or a pass phrase).
This is typically done to insulate the secondary keys from each other, to avoid that leakage of a secondary key compromises the security of the master key, or to thwart attacks on pass phrases (e.g. via rainbow tables).
