sigtool - Man Page

sigtool [options]

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.

-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.

--tempdir=DIRECTORY

Create temporary files in DIRECTORY. Directory must be writable for the user running sigtool.

--leave-temps

Do not remove temporary files.

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.

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

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