HTTPS download location or checksum available?

[John Neffenger]

Is it possible to change the following page either to download the files 
over HTTPS or provide their checksums on an HTTPS page (as Oracle does 
for the JDK)?

   JavaFX - Gluon
   https://gluonhq.com/products/javafx/

The page redirects to an insecure HTTP connection when downloading the 
Linux files, for example:

JavaFX Linux SDK
http://gluonhq.com/download/javafx-11-sdk-linux/
--> Location: https://gluonhq.com/download/javafx-11-sdk-linux/
--> Location: 
http://download2.gluonhq.com/openjfx/11/openjfx-11_linux-x64_bin-sdk.zip

JavaFX Linux jmods
https://gluonhq.com/download/javafx-11-jmods-linux/
--> Location: 
http://download2.gluonhq.com/openjfx/11/openjfx-11_linux-x64_bin-jmods.zip

Is that the official download page outside of the Maven repositories?

Thank you,
John
