RadioKing takes care of securing your Radio website, you do not have to provide an SSL certificate to secure it.
Simply contact our team and a member of the technical team will create a certificate and add it to your website.
However, it is possible that your website may not be completely secure despite the certificate (and the presence of "https" in the link). If a website is not completely secure, your browser usually indicates this with an "open padlock" icon on the left of the URL bar.
To be totally secure, a website must not contain any content that is not secure, i.e. from a source that is not secure itself.
These are usually the images or stream of your Radio. For example, most RSS feeds do not offer secure images.
If you use a stream hosted by RadioKing, it will necessarily be secure.
