NAME
       sigtool - signature and database	management tool

SYNOPSIS
       sigtool [options]

DESCRIPTION
       sigtool	can be used to generate	MD5 checksums, convert data into hexa-
       decimal format, list virus signatures and build/unpack/test/verify  CVD
       databases and update scripts.

OPTIONS
       -h, --help
	      Output help information and exit.

       -V, --version
	      Print version number and exit.

       --quiet
	      Be quiet - output	only error messages.

       --stdout
	      Write all	messages to stdout.

       --hex-dump
	      Read data	from stdin and write hex string	to stdout.

       --md5 [FILES]
	      Generate MD5 checksum from stdin or MD5 sigs for FILES.

       --sha1 [FILES]
	      Generate SHA1 checksum from stdin	or SHA1	sigs for FILES.

       --sha256	[FILES]
	      Generate SHA256 checksum from stdin or SHA256 sigs for FILES.

       --mdb [FILES]
	      Generate .mdb signatures for FILES.

       --html-normalise=FILE
	      Create  normalised  HTML files comment.html, nocomment.html, and
	      script.html in current working directory.

       --utf16-decode=FILE
	      Decode UTF16 encoded data.

       --vba=FILE
	      Extract VBA/Word6	macros from given MS Office document.

       --vba-hex=FILE
	      Extract Word6 macros from	given MS Office	document  and  display
	      the corresponding	hex values.

       -i, --info
	      Print a CVD information and verify MD5 and a digital signature.

       --build=FILE, -b	FILE
	      Build  a	CVD  file.  -s,	 --server is required for signed virus
	      databases(.cvd), or, --unsigned for unsigned(.cud).

       --max-bad-sigs=NUMBER
	      Maximum number of	mismatched signatures when building a CVD. De-
	      fault: 3000

       --flevel
	      Specify a	custom flevel. Default:	77

       --cvd-version
	      Specify the version number to use	for the	build. Default	is  to
	      use  the	value+1	 from  the  current  CVD  in  --datadir. If no
	      datafile is found	the default behaviour is to prompt for a  ver-
	      sion  number,  this  switch will prevent the prompt.  NOTE: If a
	      CVD is found in the --datadir its	version+1  is  used  and  this
	      value is ignored.

       --no-cdiff
	      Don't create a .cdiff file when building a new database file.

       --unsigned
	      Create a database	file without digital signatures	(.cud).

       --server
	      ClamAV  Signing  Service address (for virus database maintainers
	      only).

       --datadir=DIR
	      Use DIR as the default database directory	for all	operations.

       --unpack=FILE, -u FILE
	      Unpack FILE (CVD)	to a current directory.

       --unpack-current
	      Unpack a local CVD file (main or daily) to current directory.

       --diff=OLD NEW, -d OLD NEW
	      Create a diff file for OLD and NEW CVDs/INCDIRs.

       --compare=OLD NEW, -c OLD NEW
	      This command will	compare	two text files and  print  differences
	      in a cdiff format.

       --run-cdiff=FILE, -r FILE
	      Execute update script FILE in current directory.

       --verify-cdiff=FILE, -r FILE
	      Verify DIFF against CVD/INCDIR.

       -l[FILE], --list-sigs[=FILE]
	      List  all	signature names	from the local database	directory (de-
	      fault) or	from FILE.

       -fREGEX,	--find-sigs=REGEX
	      Find and display signatures from the  local  database  directory
	      which match the given REGEX. The whole signature body (name, hex
	      string, etc.) is checked.

       --decode-sigs=REGEX
	      Decode  signatures  read from the	standard input (eg. piped from
	      --find-sigs)

       --test-sigs=DATABASE TARGET_FILE
	      Test all signatures from DATABASE	against	TARGET_FILE. This  op-
	      tion  will only give valid results if the	target file is the fi-
	      nal one (after unpacking,	normalization,	etc.)  for  which  the
	      signatures were created.

       --print-certs=FILE
	      Print Authenticode details from a	PE file.

ENVIRONMENT VARIABLES
       Sigtool uses the	following environment variables:

       SIGNDUSER - The username	to authenticate	with the signing server	when
       building	a signed CVD database.

       SIGNDPASS - The password	to authenticate	with the signing server	when
       building	a signed CVD database.

EXAMPLES
       Generate	hex string from	testfile and save it to	testfile.hex:

	      cat testfile | sigtool --hex-dump	> testfile.hex

CREDITS
       Please check the	full documentation for credits.
