Mac, Windows

In PDF Studio 9, we’ve added support for the Windows certificate stores. Windows users are able to sign using smart cards / USB/ hardware tokens through their operating system store. This is the technology used for instance in DOD Cac Certificates.

Mac

Unfortunately MacOS currently has a bug that prevents us from accessing token certificates. When we make a call to the system MacOS is returning a false value even though the token is listed as available.

In version 11.0.4 of PDF Studio, we will be opening smart-card token signing to Mac users by allowing them to specify the link to a PKCS11 token configuration file.  Please read this entry in our knowledge base:

Linux / Unix

Unfortunately Linux does not have this kind of store / framework that abstracts the complexity of accessing certificates.

In version 10.1 of PDF Studio, we will be opening smart-card token signing to Linux users by allowing them to specify the link to a PKCS11 token configuration file.  Please read this entry in our knowledge base:
