History
Expert Witness (for Windows) was the original name for EnCase (dating back to 1998). More info about this can be found on the Internet Archive 1 including a demo of the original software 2.
File Format
Hash Databases
EnCase uses MD5 hashes and stores them in its proprietary Encase hash file format; either individually or in a "hash map". EnCase supports importing hashes from the NSRL, Hashkeeper, and plain MD5 files.
