Hello Harinath,

It seems this exception is related to a known issue that we have already logged in our backlog: PdfProcessing: CryptographicException is thrown when saving with PdfStreamWriter or importing with PdfFormatProvider.

I am afraid I cannot provide you with a workaround until this issue is fixed, so please, make sure to subscribe to the task by clicking the Follow button so you can receive updates when its status changes.
