Hi, I have 10 years experience in digital signature. I have created many apps, service, web service,.. to sign pdf document. I understand your case, what we need to do is: 1. Calculate hash value from original Pdf document 2. Calculate signature from the hash value (maybe you will send the hash value to other service to calculate signature or you can do it yourself) -> this is pkcs#7 signature. 3. Embeled(add) the signature (pkcs#7) into original pdf document (in step 1) to create signed pdf With my experience and I have completed projects like this, so I think I can help you complete the project fastest. Please check my profile, I have completed many projects about digital signature in the Freelancer. https://www.freelancer.com/u/tuantag Contact me if you interested! Thanks for reading!
