Abstract

A method, system, and device for encrypted packet inspection allowing an authorized third party device to monitor cryptographic handshaking information (full- duplex) between two other devices and together with the secret private key then transparently decrypt the bulk encrypted data stream.The scope of this invention encompasses many applications, three examples of which are firewalls, load balancers, and local network caches. Additionally, this invention achieves and contributes to the efficient handling of encrypted information in other ways, three examples of which are making switching, routing, and security decisions.
