WhatsApp has some common tricks as well as session tricks which play significant duties in end to end encryption. Identification key, authorized pre-key and one-time pre-keys are known as public secrets; each having various size of contour set. On the other hand, session tricks are likewise of 3 kinds; root key, chain secret and message key.

ECDH(I_initiator,S_recipient) ||ECDH(E_initiator,I_recipient)||
ECDH(E_initiator,S_recipient) ||ECDH(E_initiator,O_recipient)
