[poppler] Pdfsig checking revocation list

[Andrés Soria]

Hello everyone.  Hope you are doing well.

I need to work with some government documentation that has a digital
signature on it with the local ID card.
Until now I was working with adobe reader 9.5 for linux wich whenever I
opened a document It checked the signature going through the internet and
downloaded the revocation list.

We are looking forward to stop using adobe reader for linux (It is old
software and has a lot of security issues) and replace it with okular wich
uses poppler and pdfsig to verify signatures.

As far as we know testing okular signatures are checked ok but only
identity and integrity, we can not make or we don't know how to use it to
check revocation as it did Adobe reader.

How does pdfsig check revocation list on the internet?  Or we have to
download the crl file and make pdfsig check locally?

Thanks for the help.

Regards.
Andrés.
