NAME

       sigtool - signature and database management tool

SYNOPSIS

       sigtool [options]

DESCRIPTION

       sigtool  can be used to generate MD5 checksums, convert data into hexadecimal 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 version 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.

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
