    摘要: An apparatus, system, and method are directed towards parsing and selectively encrypting different portions of data in real-time, decrypting the encrypted data in real-time, and passing the data to a media player on a client computer or other network capable device. Data in a network packet may be parsed into payload and non-payload portions. The payload portion of the packet data may then be examined to determine whether a predefined type of the data is recognized. For example, in one embodiment, the predefined data type may be media content. If the payload portion is recognized as a predefined data type, then it may be selectively encrypted. The selectively encrypted payload portion and non-payload portion of the packet may then be combined, such that the non-payload portion may be employed by firewalls, proxies, and/or NATs to route the packet towards the client computer or other network capable device.
