Class SessionKeyAndNonce

java.lang.Object

net.i2p.data.SimpleDataStructure

net.i2p.data.SessionKey

net.i2p.router.crypto.ratchet.SessionKeyAndNonce

All Implemented Interfaces:

net.i2p.data.DataStructure

class SessionKeyAndNonce
extends net.i2p.data.SessionKey

A session key is 32 bytes of data. Nonce should be 65535 or less. This is what is returned from RatchetTagSet.consume(). RatchetSKM puts it in a RatchetEntry and returns it to ECIESAEADEngine.
