Class KeyValidator

java.lang.Object

io.github.fherbreteau.vodozemac.KeyValidator

public final class KeyValidator
extends Object

Utility for validating encryption keys used by the vodozemac pickle format.

vodozemac encrypted pickles require a 256-bit (32-byte) key. This class centralises that validation to avoid duplication across the classes that support encrypted pickling (Account, OlmSession, OutboundGroupSession, InboundGroupSession, etc.).
