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 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.

OPTIONS
       -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.

       -nocert
	      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.)
