|
|
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.
|
|
<P>
|
|
|
|
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:
|
|
<DL COMPACT>
|
|
<DT id="1">•<DD>
|
|
If the -nssdir option is specified, the directory specified by this option.
|
|
<DT id="2">•<DD>
|
|
The NSS Certificate database in the default Firefox profile. i.e. $HOME/.mozilla/firefox/*.default.
|
|
<DT id="3">•<DD>
|
|
The NSS Certificate database in /etc/pki/nssdb.
