Answer 1

This will only work from an HTTP or HTTPS site with a Valid and trusted security certificate.

If there's a certificate error, iOS will not load the image. Temporarily trusting the certificate in Safari for the page will not trust the certificate for the homescreen shortcut. If you are using a self-signed certificate, you must add the untrusted root certificate as a trusted certificate at the OS level.

1. On the iOS device, navigate to a page which has a link to the .crt file
2. Tap the link
3. Approve/Install through all the confirmation screens
