NAME

       pdfsig - Portable Document Format (PDF) digital signatures tool

SYNOPSIS

       pdfsig [options] [PDF-file]

DESCRIPTION

       pdfsig  verifies  the digital signatures in a PDF document.  It also displays the identity of each signer
       (commonName field and full distinguished name of the signer  certificate),  the  time  and  date  of  the
       signature,  the  hash  algorithm used for signing, the type of the signature as stated in the PDF and the
       signed ranges with a statement wether the total document is signed.

       The signer certificate validation uses the trusted certificates stored in the Network  Security  Services
       (NSS) Database. The NSS Database is searched for in the following locations:

       •      If the -nssdir option is specified, the directory specified by this option.

       •      The     NSS     Certificate     database     in     the     default    Firefox    profile.    i.e.
              $HOME/.mozilla/firefox/*.default.

       •      The NSS Certificate database in /etc/pki/nssdb.

OPTIONS

       -nssdir [prefix]directory
              Specify the database directory containing the certificate and key database files. See  certutil(1)

              DESCRIPTION are used.
