The Cert2SPC tool creates test Software Publisher Certificates (SPCs) from existing X.509 certificates, enabling developers to generate test certificates for code signing during development. Cert2SPC can wrap multiple X.509 certificates into a PKCS #7 signed-data object. The tool is installed in the \Bin folder of the Microsoft Windows Software Development Kit (SDK) installation path.
Cert2SPC is available as part of the Windows SDK, which you can download here.
