       sigtool - signature and database management tool

       sigtool [options]

       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.

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

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

              Be quiet - output only error messages.

              Write all messages to stdout.

              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.

              Create  normalised  HTML files comment.html, nocomment.html, and
              script.html in current working directory.

              Decode UTF16 encoded data.

              Extract VBA/Word6 macros from given MS Office document.

              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).

              Maximum number of mismatched signatures  when  building  a  CVD.
              Default: 3000

              Specify a custom flevel. Default: 77

              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.

              Don't create a .cdiff file when building a new database file.

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

              Use DIR as the default database directory for all operations.

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

              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  signatures  read from the standard input (eg. piped from

       --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 Authenticode details from a PE file.

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

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