Directory Catalog Description:            

Directory Catalog is a
powerful utility for system administrators and other advanced users wanting
to keep track of, and analyze, file and system changes. These changes can
occur for a variety of
reasons including normal software use and upgrades, or more menacing
realities of modern computing
like virus' and Trojan horses. Directory Catalog keeps a "snapshot"
database, or Catalog, of all
files in a directory, or multiple directories. Within each database,
information is contained for
each file that existed at the time the database was generated. This
information includes standard
file date, time, and size data, but much more importantly it can contain a
"Digital Signature" of
the file and, for binary files, Version Information encoded by the vendor.
Any change to any aspect
of a file will be detected by Directory Catalog and displayed for your
analysis. It simply is not
possible for something to change and not be detected. Of course, Directory
Catalog also picks up
on missing and new files, in addition to changes. Digital Signatures are
generated using the
RSA Data Security, Inc. MD5 Message-Digest Algorithm code developed by RSA
Data Security, Inc. MD5,
or Message Digest 5, is a powerful, fast, and extremely hard to crack code
base for generating
digital signatures for files, or any arbitrary length of data. This code is
used in Directory
Catalog, but it copyright and owned by RSA Data Security, Inc. MD5 is
discussed in detail in
Internet Request For Comments (RFC) 1321 available at
http://www.internic.net/.
