Class ZrtpStateClass

  • public class ZrtpStateClass
extends Object
    This class is the ZRTP protocol state engine. This class is responsible to handle the ZRTP protocol. It does not handle the ZRTP HMAC, DH, and other data management. This is done in class ZRtp which is the parent of this class. The methods of this class implement the ZRTP state actions.
