Cit - Cryptographic Integrity Tool

CyberSoft, Inc.'s Cryptographic Integrity Tool is part of the VFind Security ToolKit. An MD5 signature (i.e., a cryptographic hash code) is generated for each file and compared to a previous signature for that file stored in a database (by default, cit.db; this can be overridden with the -db option). A list of new and modified files is written to standard output. A report of new, modified and deleted files is placed in cit.rpt (by default; again, see the -db option).

OPTIONS

-c, --copyright

Display copyright information and then exit. All other options will be ignored.

-h, -?, --help

Display usage message and then exit. All other options will be ignored.

-v, --version

Display version information and then exit. All other options will be ignored.

--cleanup

Totally remove all cit work and database files. Suitable for use when you want a totally new database or want to release the disk resources that cit is using. Use with caution!

-db databasename, --database-name databasename

Use databasename as the base name for the database. The database itself would be named databasename.db, the report file, databasename.rpt

--dbpath databasepath

Use databasepath as the directory in which the database is located. Default: Current directory.

-nb, --no-backup

Don't retain the old database after the run (typically kept in cit.db0).

-nr, --no-report

Do not generate the cit.rpt report file.

-nu, --no-update

Report changes in the file system, but don't update the database.

-fc, --file-changed

Hash the file and compare the hash value with the value found in the Cit database. Report whether the file has changed or not.

-dc, --dupcontents

Reports (usually in Cit.rpt) all of the files that have duplicate hash values.

-df, --dangerfile

Reports (usually in Cit.rpt) all of the files/hashes that are found in the Danger file database.

-S, --stdin

Display the MD5 hash of standard input on standard output.

LICENSES

Cit requires a LICENSE file to run. This LICENSE file is host specific, therefore cit will only run on the licensed machine. Additional licenses may be purchased by contacting:

CyberSoft, Inc.
1508 Butler Pike
Conshohocken, PA 19428.
Phone: +1.610.825.4748
Fax: +1.610.825.6785

At start-up, cit searches for the LICENSE file in these locations:

• /LICENSE
• /etc/LICENSE
• The current working directory.
• The VSTK library directory configured during installation.

INPUT

cit can take input in three ways.

1. cit with a filename argument. In this mode cit will generate a MD5 signature for that file and write it to stdout. No database is created or updated.

   Example:

   
   cit HelloWorld.java
   

2. cit reading a data stream from the standard input. In this mode cit will generate a MD5 signature for the data stream and write it to stdout. No database is created or updated.

   Example:

   
   cat BigFile.tar | cit -S
   

3. cit reading a list of filenames from the standard input. This is the default mode of operation. In this mode, it accepts a list of filenames on standard input. A MD5 signature (i.e., a cryptographic hash code) is generated for each file and compared to a previous signature for that file stored in a database (by default, cit.db; this can be overridden with the -db option). A list of new and modified files is written to standard output. A report of new, modified and deleted files is placed in cit.rpt (by default; again, see the -db option).

   Example:

   
   find / -type f -print | cit
   

LICENSE, cit.db, cit.rpt, cit.db0.

vfind(1), thd(1), bhead(1), jdis(1), uad(1), find(1).

Please report all bugs to support@cyber.com Make sure to include the version of cit, the platform and OS, the script or command used, the complete output showing the bug, a short description of the problem, and contact information.
