Which signature handler to use when timestamping data

Hi,

I am struggling to validate my timestamped data with my signature handler. I how also need to be able to validate the signatures using Adobe default security handler. I currently have my handler set for PROP_PSENG_SignFormatPKCS7DetachedDigest. I see that there is also a handler property PROP_PSENG_SignFormatETSIRFC3161Digest.

If I want to include a timestamp from a TSA so that Adobe reports that the signature has been timestamped should I change the handler to PROP_PSENG_SignFormatETSIRFC3161Digest?

I see that Adobe default security's subfilter is adbe.pkcs7.detached, so I should be able to accomplish timestamping with PROP_PSENG_SignFormatPKCS7DetachedDigest?

Regards,
