Abstract
In certain embodiments, a method includes receiving, by a capture device, traffic flows transmitted by a plurality of client devices, each of the traffic flows being associated with one of the plurality of client devices and comprising encrypted data. The method further includes receiving, by the capture device, flow information communicated from a proxy server communicatively coupled to the capture device, the flow information comprising an identification of a particular traffic flow and a session key associated with the particular traffic flow. The method further includes storing, by the capture device, encrypted data of the particular traffic flow identified by the flow information supplied by the proxy server; storing, by the capture device, the session key associated with the particular traffic flow; and discarding, by the capture device, any of the plurality of received traffic flows not identified in the flow information received from the proxy server.
