Support to provide hash of the PDF file to sign PDF document externally

Hello,

Is it possible to use an already signed hash of a document and add it to the document as a signature? This would be very valuable in instances where the private key is not available except via an api call e.g. with Azure Key Vault or using a private key obtained from a smart card through a PKCS#11 interface etc.

Hello

Document .Net may work with digital signatures.
But, what you want to implement, our component doesn't support in the current time.

We will try to add in next versions of the dll.

Thanks
