ABSTRACT:
Methods, systems, and products are disclosed for specifying a signature for an encrypted packet stream. One method receives the encrypted stream of packets, and encryption obscures the contents of a packet. A signature for insertion into the stream of packets is specified, and the signature identifies a type of data encrypted within the stream of packets. The signature identifies the contents of the packet despite the encryption obscuring the contents.
