== Create Root Authority Certificate ==
Create a self-signed root authority certificate , which has to be installed on the [[UBIK Windows 8 Client Certificate|Client]] and the [[UBIK_Web_Service#Certificate|Server]], using the command
<code>makecert -n "CN=<ROOTNAME>" -r -sv <ROOTNAME>.pvk <ROOTNAME>.cer</code>
where '''ROOTNAME''' ... self-signed root authority name (see [http://msdn.microsoft.com/en-us/library/bfsktky3%28VS.110%29.aspx MSDN]). This certifiate has to be installed on the [[UBIK Windows 8 Client Certificate|Client]] and the [[UBIK_Web_Service#Certificate|Server]].
{{Hint|This step can be ignored if there is already a valid root authority certificate installed on the server and the client!}}
