> I want to use "https" instead of "http" for the server url.
This is covered in the SDK-Tutorial-html doc, section "Registering your plugin package as a vCenter Server extension".
You will need something like this in your VC extension:
<server>
<url>https://a-web-server-path/mypluginPackage.zip</url>
<description>
<label>My plugin</label>
<summary>My first vSphere Client plugin</summary>
</description>
<company>VMware</company>
<-- SHA1 thumbprint of the server hosting the .zip file -->
<serverThumbprint>3D:E7:9A:85:01:A9:76:DD:AC:5D:83:1C:0E:E0:3C:F6:E6:2F:A9:97</serverThumbprint>
<type>HTTPS</type>
<adminEmail>your-email</adminEmail>
</server>
