       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 following locations:

       o      The NSS Certificate database in the default Firefox profile.

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

       -dump  Dump all signatures into current directory.

       -v     Print copyright and version information.
