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.
              Default: 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
              (default) 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
              option  will  only  give valid results if the target file is the
              final one (after unpacking, normalization, etc.) for  which  the
              signatures were created.

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

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

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