A PE file can be dual signed by applying multiple signatures, which is strongly recommended when using deprecated hashing algorithms such as MD5.
Source: Īs hash algorithms, Authenticode supports MD5 (only for backward compatibility), SHA-1, and SHA-256 hashes. PE parts included in Authenticode hash calculation. For example, the Checksum field from Optional Header needs to be recalculated once the certificate is embedded into the PE file.įigure 1. Regarding the hash calculation, it excludes certain parts of the PE header that are altered in the signing process itself (shown in gray color in Figure 1). Roughly speaking, the Authenticode signature is a binary data blob consisting of a certificate and a signed hash of the PE file. The Authenticode signature of a PE file follows the PKCS#7 structure that includes the signature (the hash value of the PE file), a timestamp (optional) and the certificate chain.

Among other files, it is normally used to sign Portable Executable (PE) files such as executable (.

Microsoft AuthenticodeĬode signing (called Authenticode in Windows) helps to establish trust in computer software, since it authenticates the software publisher and guarantees code integrity through the validation of the digital signature shipped within the software. In this post, we will describe code signing and how it is performed in Windows OS.

You can manually install the Authenticode certificates into the Trusted Publishers certificate store on a computer by using the CertMgr tool.Have you ever wondered what is going on under that annoying Windows pop-up message telling you that a trusted application is going to make changes in your computer? If you have, keep reading.įor these curious people, this trusting chain is accomplished thanks to code signing. 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.
#Microsoft authenticode root authority driver#
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.
