org.whispersystems.libsignal.groups.ratchet.SenderChainKey

public class SenderChainKey
extends java.lang.Object

Each SenderKey is a "chain" of keys, each derived from the previous. At any given point in time, the state of a SenderKey can be represented as the current chain key value, along with its iteration count. From there, subsequent iterations can be derived, as well as individual message keys from each chain key.
