# nessus-check-signature(1)

A simple utility to check (or generate) the signature of plugins retrieved from www.nessus.org

## NAME

nessus-check-signature - A simple utility to check (or generate) the signature of plugins retrieved from www.nessus.org

## SYNOPSIS

**nessus-check-signature \[-S\] filename \[signaturefile\]**

## DESCRIPTION

**nessus-check-signature** is a simple utility used by  **nessus-update-plugins** to check the signatures of the Nessus plugins downloaded from  www.nessus.org. When executed and provided both an archive and a signaturefile it will verify if the file matches the signature  and if the signature matches the  **nessus\_org.pem** certificate.

It can also generate the signatures for the plugins distributed by www.nessus.org but you will, obviously, need the private certificate file to do so. You can, however, customise the code to use an alternate certificate file and generate plugins distributions files for third party servers.

## OPTIONS

- **-S**

  Sign the archive instead of checking the signature.  **nessus-check-signature** will check for the private certificate key **nessus\_org.priv.pem** and will generate a **.sig** file with the file signature.

## EXAMPLE

To check the signature for all the plugins downloaded from the Nessus servers use:

**nessus-check-signature all-2.0.tar.gz all-2.0.sig**

## EXIT VALUES

**nessus-check-signature** will return with a 0 value if the signature matches and will return with an error value (1) if the signature does not match or if any other error is found.
