Signing a Catalog File with an SPC

Use the following SignTool command to sign the catalog file of a kernel-mode driver package with a Software Publisher Certificate (SPC). For 64-bit versions of Windows Vista and later versions of Windows, kernel-mode driver packages that do not have a WHQL release signature must be signed with an SPC signature to comply with both the kernel-mode code signing policy and the PnP device installation signing requirements.

SignTool sign /v /ac CrossCertificateFile /s SPCCertificateStore /n SPCCertificateName /t http://timestamp.verisign.com/scripts/timstamp.dll CatalogFileName.cat


  • The sign command configures SignTool to sign the catalog file CatalogFileName.cat.

  • The /v verbose option configures SignTool to print execution and warning messages.

  • The /ac CrossCertificateFile option specifies the cross-certificate .cer file that is associated with the Software Publisher Certificate (SPC) that is specified by SPCCertificateName.

  • The /s SPCCertificateStore option specifies the name of the certificate store that holds the Software Publisher Certificate that is specified by SPCCertificateName. As described in Software Publisher Certificate (SPC), the certificate information must be contained in .pfx file, and the information in the .pfx file must be added to the Personal certificate store of the local computer. The Personal certificate store is specified by the option /s my.

  • The /n SPCCertificateName option specifies the name of the certificate in the SPCCertificateStore certificate store.

  • The /t http://timestamp.verisign.com/scripts/timstamp.dll option supplies the URL to the publicly-available time-stamp server that VeriSign provides.

  • CatalogFileName.cat is the name of the catalog file.

For example, the following command signs the Tstamd64.cat catalog file with the SPC named "contoso.com" in the Personal "my" certificate store and the corresponding cross-certificate Rsacertsvrcross.cer. The signature is time-stamped by the service http://timestamp.verisign.com/scripts/timstamp.dll. In this example, the catalog file is in the same directory in which the command is run.

SignTool sign /v /ac c:\lab\rsacertsrvcross.cer /s my /n contoso.com /t http://timestamp.verisign.com/scripts/timstamp.dll tstamd64.cat
