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.

       locations:

       •      The NSS Certificate database in the default Firefox profile.

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