Hello,

I have a problem with validating document signed with PAdES signature including timestamp. I signed two documents (the same signing and timestamping mechanism - using standalone application for signing). One of them is validated properly (including timestamp) and second one shows that the signature contains timestamp which may by invalid. These two documents differs only in certificate of timestamping authority. Does anybody could help with this issue ? Why Adobe Reader presents timestamp made with second certificate as invalid while both certificates were created according to RFC 3161.

 

Certificate which signs valid timestamp:
