ECDH(I_initiator,S_recipient) ||ECDH(E_initiator,I_recipient)||
ECDH(E_initiator,S_recipient) ||ECDH(E_initiator,O_recipient)
Similarly, HKDF code is made use of to create chain & origin secrets from the Master Trick code by both the initiator as well as the recipient during each time of message exchange.

This guarantees no 3rd party can breach the wall and also can obtain accessibility to the delivered data between customer and web server. The process is carried out by numerous noise pipes for long running interactive link.
