Overview

This class handles Nonce payloads, as defined in RFC 7296 §3.9.

A Nonce payload contains a generic payload header (see Payload) and data field (type Types::String):

Create a Nonce payload

# Create a IKE packet with a Nonce payload
pkt = PacketGen.gen('IP').add('UDP').add('IKE')
pkt.add('IKE::Nonce', data: "abcdefgh")
pkt.calc_length
