Overview

Universa KeyRecord. This structure is intended to hold small encrypted entity, usually a key to other, big encrypted entity. KeyRecord maximum plaintext size is small, so everything that could be large than say 128 bytes should be encrypted using a key stored as plaintext in the KR.

This class is not directly instantiable, use one of its ancestors, like Pbkdf2CryptoRecord, or decode packed binary record.
