Hello
Is there any way to tell Adobe reader to automatically check signatures made by Eldos? We have a problem because users have to manually choose handler for verifying signatures (picture is in attachment). Also when they try to validate our PDF signature with this site https://pruefung.signatur.rtr.at/en/index.html they get following message:
Quote
The signature could not be verified since this type of signature is not supported.
Probably this signature was created using a 3rd party tool.
In that case please use that software for verification purposes.

Is there some way to fix this?

Thanks

I think this FAQ article should address your question.

Thank you very much Eugene
When I have set CustomName property of TElPDFAdvancedPublicKeySecurityHandler Adobe reader was able to automatically validate signature. However mentioned site still refuses to validate signature made by blackbox. What can we tell?

It can happen that the site doesn't handle PAdES or the used form of PAdES or anything else - we can only guess. What you can try is create a regular PDF signature (check with both visible and invisible signatures) and validate the doucment with the site. One more assumption is that they want certificate (not a signature) of certain type. The best option is of course to contact the site owner for clarification.

Yap, you're right Eugene!
I just checked and they can only verify standard signatures, not PAdES ones.

Thank you.
