We are sorry for the inconvenience caused.

Best Regards,

Unfortunately, the linked ticket ID PDFNET-40715 is pending for the analysis and not resolved yet. It is a complex task and can take time than usual. We will let you know once a significant progress has been made in this regard.

Thanks for your patience.

Our product team has further investigated the feasibility of requested feature about .p7b certificate support for digital signature and as per their feedback, the .p7b file can contain only certificates and chain certificates, but not the private key which used for signing. So I am afraid that the requested requested feature cannot be offered.

In case of any further assistance, please feel free to contact us.
