So far, you had to download (or order) the entire database on 3 CD-ROMs. But with the Internet Storm Center's online search of the database, you can check an individual file quickly to see if it is "valid" (http://isc.sans.org/tools/hashsearch.html). The database includes about 39 Million hashes of various files collected by NIST. The database includes commercial as well as open source software like many Linux distributions. The Internet Storm Center is looking for help to extend the database beyond the scope of what is provided by NIST.
