Hi Tomek,
Can you show a code place where you add a timestamp?
Do you include in your signature dictionary "M" with time of signing?

Hi
I have a problem with timestamp of digital signature. I create this
signature as 'adbe.pkcs7.detached ' and everything works fine. Now I want
to add a timestamp to the signature (by adding ASN.1
'id-smime-aa-timeStampToken' atribute to PKCS7 signature as in RFC 3161
Appendix A). When i open this created pdf the signature is visible , it
is verified, but acrobat reader does't show time of signature nor
timestamp authority (on Data/Time tab of signature properties) only 'Not
available' text is shown (it shows only info: siignature is timestamped
but the timestamp could not be verified)
When I open a sample document prepared by adobe which contains signature
with timestampi can see signing date and timestamp authority.
I think there is a problem of parsing the signature by security handler.
Do you have any ideas or expierences with timestamped signaatures?
