9. An apparatus comprising: a computer system including a classified environment including a collection of data including both classified binary data and unclassified binary data; a plain text format file including a plurality of attributes, wherein the plain text format file describes each of the attributes in a message data structure in a classified network on a message type basis, wherein at least one of the attributes comprises a security mark; a software application programmed for execution within the classified environment, the software application comprising a trusted download toolkit programmed for: (a) processing at least one message contained within the collection of data by receiving target input data associated with the message, wherein the target input data comprises a binary data stream comprising classified binary data, a binary data stream comprising unclassified binary data, or a combination thereof, (b) identifying security mark data in at least one of the binary data streams, (c) identifying a level of classification for at least a portion of the target input data in response to the security mark data, and (d) extracting at least a portion of the unclassified binary data from the collection of data in the classified environment in response to the identified level of classification; wherein the trusted download toolkit is independent of the message data structure within the classified environment; and an unclassified environment including a memory configured to receive the extracted unclassified binary data.
