You must enable FIPS mode in the client operating system before you run the client installer if you plan to install Horizon Client with FIPS-compliant cryptography.
When FIPS (Federal Information Processing Standard) mode is enabled in the client operating system, applications are informed that they should only use cryptographic algorithms that are FIPS-140 compliant and in compliance with FIPS-approved modes of operation. You can enable FIPS mode by enabling a specific security setting, either in the Local Security Policy or as part of Group Policy or by editing a Windows Registry key.
For more information about FIPS support, which is available with Horizon 6 version 6.2 or later, see the View Installation document.
Setting the Configuration Property
To enable FIPS mode in the client operating system, you can either use a Windows GPO or use a Windows Registry setting for the client computer.
- To use the GPO setting, open the Group Policy Editor and navigate to:
Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options
Enable the System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing setting.
- To use the Windows Registry, go to the following Registry key:
To enable FIPS mode, set Enabled to 1.
