Hi Arjun,
Our PDF library has support to digitally sign the PDF documents from windows certificate store, This means you will be able to apply the signature by accepting the certificate provided by the certificate store. Please refer the below link for loading the certificate from certificate store and sign the PDF document.
A secure way to store a digital ID is using a Windows certificate store. If a root certificate is added in a Windows certificate store, you don’t need to add and trust each of the certificates that are already present in a Windows certificate store manually.
You can retrieve the digital ID “X509Certificate2” from the Windows certificate store and use it to add a digital signature to a PDF document.
When the USB token is connected to the system, the certificates in the token are added automatically to the Windows Certificate Store under the store name “My”. To sign the document using a certificate installed on the USB token you need to know the issuer common name & the serial number of the certificate, and a valid password or PIN to access the USB token. After that, you can digitally sign a PDF document using the Windows certificate store.
Please let us know if you need any further assistance with this.
Regards,
Gowthamraj K
