21.05.21 – SHA-2 support in Microsoft Windows for installing Kaspersky Security 11.0.1 for Windows Server (#Ksws11)


mardi 25 mai 2021

This article concerns Kaspersky Security 11.0.1 for Windows Server (version 11.0.1.897).
Microsoft no longer supports root certificates, which provide the ability to sign code that runs at the kernel level of the operating system—a driver code. Drivers are now signed using the WHQL (Windows Hardware Quality Lab) signature, which is based on the SHA-2 (SHA-256) hashing algorithm. Verification of such a signature requires SHA-2 support in the operating system.

Before installing Kaspersky Security 11.0.1 for Windows Server on a protected device with an operating system from the list below, please make sure that the system has updates that bring SHA-2 support. During the installation of Kaspersky Security 11.0.1 for Windows Server, SHA-2 support in the operating system is verified. If there is no SHA-2 support, then the installation is aborted.

Depending on the installation method, proceed as follows:

  • When installing using the Installation Wizard, a notification about the lack of SHA-2 support is displayed, allowing you to abort or continue the installation.
  • When installing from the command line or remotely, you can ignore the verification by specifying the SKIP_SHA2_KB = 1 key.

Skip the SHA-2 verification only if you are sure that the OS on the protected device supports SHA-2.

If the OS on the protected device lacks SHA-2 support, the correct installation of the application modules, their operation, as well as the correct operation of the OS cannot be guaranteed.
Microsoft Windows updates with SHA-2 support
