There is no way to decrypt data where ephemeral ciphers are used. This is indicated by the use of a ServerKeyExchange message. Important: Ensure t he use of a Diffie-Hellman Ephemeral (DHE/EDH) or RSA Ephemeral cipher suite is not negotiated between the two hosts.Ideally, ensure any capture either a) is of packets related to an entirely new device connecting or b) where a device that has already previously established a session is used, it is used after a considerable time after the last session was established. Beware captures taken where a session has been resumed. In other words, the CLIENTHELLO and SERVERHELLO exchange.
