The workload seems to be high and the profits are weak. If you feel like it, add this functionality and we will share it with others.

I think I have done the work for OSCP response and CRL response, I can share the code once I can verify it works for all cases. I wanted help where I can plugin timestamp. I am looking for direction.

Read in asn1crypto/cms.py - in the signature structure there is room for crl/ocsp/timestamp, I have only completed the required bare minimum

@pkumar-uk Do you have a working code for OCSP enabled certificates? I'm very interested in it.

example in pdf-sign-cms-hsm-certum.py
There are new parameters (optional) for pdf.cms.sign, i.e .: ocspurl and ocspissuer. The former is the address of the certificate provider's ocsp service, and the latter is the certificate of the certificate issuer of this service.
