You need to consider the order of the packets are not important, you need to find the packets with the type ciphered data (or some else). Consider the ciphered messages can has various encripted packets for various keys, and a key (Public or private) can has various subkeys. If you need to know with which key you can decrypt a message, you have to search all keys from de message on all subkeys on your private keys.
