SYNOPSIS

DESCRIPTION

12       pdfsig verifies the digital signatures in a PDF document.  It also dis‐
13       plays the identity of each signer (commonName field  and  full  distin‐
14       guished  name of the signer certificate), the time and date of the sig‐
15       nature, the hash algorithm used for signing, the type of the  signature
16       as  stated in the PDF and the signed ranges with a statement wether the
17       total document is signed.
18
19       The signer certificate validation uses the trusted certificates  stored
20       in the following locations:
21
22       ·      The NSS Certificate database in the default Firefox profile.
23
24       ·      The NSS Certificate database in /etc/pki/nssdb.
