The catalog file is then signed with an embedded signature. This hash value is included in a catalog file.

cat), the signing process requires generating a file hash value from the contents of each file within a driver package. For more information about this process, see Embedded Signatures in a Driver File. With embedded signatures, the signing process embeds a digital signature within a nonexecution portion of the driver file.

The certificate is typically part of a chain of such certificates, ultimately referenced to a well-known CA such as VeriSign.Īuthenticode code signing does not alter the executable portions of a driver. The certificate data includes the publisher's public cryptographic key.

#MICROSOFT AUTHENTICODE ROOT AUTHORITY SOFTWARE#

It is issued by a CA only after that authority has verified the software publisher's identity. A certificate is a set of data that identifies the software publisher. Using Authenticode, the software publisher signs the driver or driver package, tagging it with a digital certificate that verifies the identity of the publisher and also provides the recipient of the code with the ability to verify the integrity of the code. Authenticode allows users to verify the identity of the software publisher by chaining the certificate in the digital signature up to a trusted root certificate. It combines digital signatures with an infrastructure of trusted entities, including certificate authorities (CAs), to assure users that a driver originates from the stated publisher. Authenticode also verifies that the software has not been tampered with since it was signed and published.Īuthenticode uses cryptographic techniques to verify publisher identity and code integrity.

#MICROSOFT AUTHENTICODE ROOT AUTHORITY INSTALL#

You can manually install the Authenticode certificates into the Trusted Publishers certificate store on a computer by using the CertMgr tool.Authenticode is a Microsoft code-signing technology that identifies the publisher of Authenticode-signed software. In this situation, the administrator adds a Certificate Rule to a Group Policy to establish trust in a publisher. Use a Group Policy to distribute certificates to an organizational unit on a network. Each certificate must be added separately to the Trusted Publishers certificate store. For example, if an Authenticode certificate from a CA was used to test-sign a driver package, adding that certificate to the Trusted Publishers certificate store does not configure all certificates that this CA issued as trusted. The Trusted Publishers certificate store differs from the Trusted Root Certification Authorities certificate store in that only end-entity certificates can be trusted. This practice should never be followed for any driver package that is distributed outside your organization. This practice of automating the installation of driver packages is only suggested for your internal systems.

By installing the Authenticode certificates in the Trusted Publishers certificate store, you can automate the installation of your driver package on various systems that are used for internal testing and debugging.

If a publisher's Authenticode certificate is in the Trusted Publishers certificate store, Windows installs a driver package that was digitally signed by the certificate without prompting the user ( silent install). The name of the Trusted Publishers certificate store is trustedpublisher. Install the Authenticode certificates on each computer in the workgroup or organizational unit that runs signed code. In order to test and debug your driver packages within your organization, your company should install the Authenticode certificates that are used to sign driver packages in the Trusted Publishers certificate store. The Trusted Publishers certificate store contains information about the Authenticode (signing) certificates of trusted publishers that are installed on a computer.
