       pdfsig - Portable Document Format (PDF) digital signatures tool


       pdfsig [options] [PDF-file]


       pdfsig verifies the digital signatures in a PDF document.  It also dis-
       plays the identity of each signer (commonName field  and  full  distin-
       guished  name of the signer certificate), the time and date of the sig-
       nature, 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:

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

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

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


       -nssdir [prefix]directory
              Specify the database directory containing  the  certificate  and
              key database files. See certutil(1) -d option for details of the
              prefix. If not specified the other search locations described in
              DESCRIPTION are used.

              Do not validate the certificate.

       -dump  Dump all signatures into current directory.

       -v     Print copyright and version information.

       -h     Print usage information.  (-help and --help are equivalent.)
