The Syncfusion native Blazor components library offers 70+ UI and Data Viz web controls that are responsive and lightweight for building modern web apps.
.NET PDF framework is a high-performance and comprehensive library used to create, read, merge, split, secure, edit, view, and review PDF files in C#/VB.NET.
I'm considering to use this library to work with PDF documents, but I need to sign PDF documents using certificates saved on smartcards (Not possible to retrieve the private key, you must sign using external Hash of the document), and I also need to attach timestamping and OCSP check to the signature.
I downloaded a demo version of Syncfusion and for the tests I made for the contents in the documentacion seems that as of now it is only possible to sign using certificates stored on PFX files. So what I explained in the first comment is not possible.

Hi Daniel,
Thank you for your interest in Essential Studio. As you said, currently we do not support adding timestamp and OCSP to a signature. We don’t have any immediate plan to implement this feature.
