All Implemented Interfaces:

DataStructure

class SessionKeyAndNonce
extends SessionKey

Session key with nonce and optional handshake state for ratchet message encryption and decryption operations, supporting nonces up to 65535 This is what is returned from RatchetTagSet.consume(). RatchetSKM puts it in a RatchetEntry and returns it to ECIESAEADEngine.
