Abstract: A system and method for tripartite encryption is given. In this system and method of encryption, a distributing party distributes keys, checksums and encrypted data among two receiving parties, so that the two receiving parties may authenticate each other without the distributing party's further intervention and encrypt and decrypt data among themselves.

Abstract: A network appliance is provided. The network appliance includes a communications sub-system for sending and receiving data packets and network interface ports for individually connecting external computing devices so that the external computing devices' data communications must traverse the network appliance before reaching any other device or destination. The network appliance further includes electronic storage and memory comprising code executable by a processor to capture data packets, extract metadata from the data packets and store the data packets and their metadata with further capabilities to parse and examine the data packets and their metadata and apply instruction sets (aka rule sets) and command where the data packets and metadata should be stored, whether they should be modified and whether they should be allowed traversal through the network appliance according to their characteristics and content.
