Hi,

I'm signing PDF files using SBB, and I'm also signing these files using TSP. In my program, when i process the PDF, the TSP timestamp is shown (and also the local date); but in Acrobat Reader (7.0.8) it says that the date is from my local computer (and i can't find where it shows the timestamp and maybe it can't handle it).

Why is this? Is a problem of my acrobat reader version?

Would you be so kind to provide us a timestamped document so that we could check it?

This is a common problem. First of all, not TSP servers are equal. Some of them are more equal, than others ;). Please do the search in the forum for more details.

You're right. I should have searched before... as another post says, with http://timestamping.edelweb.fr/service/tsp it recognizes it.

But now i've got a question... I'm using my own TSP server (made with SBB). Should I set a new ticket and post you the code of the TSP server to see how to make it compatible with pdf then? :p

No, thanks :). We are investigating the problem already. Will let you know as soon as some positive results are achieved.

Did you properly create the certificate?
Acrobat handles SecureBlackbox TSP server packets fine, when you use properly created certificate. Properly means with correct key usage as specified in RFC 3161.

Well, I've read RFC 3161; and no, i'm not using a certificate with id-kp-timeStamping; it was my personal certificate... so i'll try to make a certificate to test it.

Many thanks to point at it

If memory serves, this key usage must be the only usage for the certificate.

Can you test is this certificate is correct? adobe still says that the date is local... The password for the certificate is "test" without quotes
