If your vCenter server is installed on Windows run this command:

“C:\Program Files\Java\jre7\bin\keytool.exe" -alias aliasName -v -keystore "C:\Program Files\VMware\Infrastructure\vSphereWebClient\server\configuration\keystore" -storepass changeit -import -file path_to_file\fileName.cer


If your running a vCenter server appliance:

Copy .cer file to /tmp folder using a tool like WinSCP.
Run the following command:
/usr/java/jre-vmware/bin/keytool -alias aliasName -v -keystore /usr/lib/vmware-vsphere-client/server/configuration/keystore -storepass changeit -import -file /tmp/vCA.cer
