Abstract: For categorizing encrypted data files, a processor determines a block cipher key length for a data file based on data file contents. The processor encrypts the data file with an encryption cipher using the block cipher key length. The processor further determines a data type for the encrypted data file from macroscopic artifacts of the encrypted data file.

Abstract: A snowplow attachment for mounting to the front end of a vehicle that includes both a push blade operable during forward movement of vehicle and a pull blade operable during reverse movement of the vehicle. The pull blade drops down in front of the push blade such that pushed snow can then be pulled back. The snowplow can get up close to permanent structures such as buildings and remove snow therefrom. During the push mode, the pull blade is raised to avoid interference with pushed snow. The snowplow can include side plates located on the ends of the blades for containing the snow and prevent snow from escaping out the sides, thereby increasing the volume of snow moved by the plow during one sweep. According to one embodiment, the snowplow includes a push blade assembly that is adapted to mount directly on the vehicle and a movable pull blade carried by the push blade assembly.
