You can add high-strength cipher suites for greater assurance, but first you must update the local_policy.jar and US_export_policy.jar policy files for JRE 7 on each View Connection Server instance and security server. You update these policy files by downloading the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 7 from the Oracle Java SE Download site.
If you include high-strength cipher suites in the list and do not replace the policy files, you cannot restart the VMware Horizon View Connection Server service.
The policy files are located in the C:\Program Files\VMware\VMware View\Server\jre\lib\security directory.
For more information about downloading the JCE Unlimited Strength Jurisdiction Policy Files 7, see the Oracle Java SE Download site: http://www.oracle.com/technetwork/java/javase/downloads/index.html.
After you update the policy files, you must create backups of the files. If you upgrade the View Connection Server instance or security server, any changes that you have made to these files might be overwritten, and you might have to restore the files from the backup.
