HTTPS is a cornerstone to the web security, no credendial should be sent to a server without using any cryptographic mecanism. This is why we offer you to use custom SSL certificates for your domain names.
So far, you were able to add a custom domain name but if you tried to reach any of your custom domains using HTTPS, it would have resulted in a warning telling you that the certificate cannot be trusted.
This is over! You are now allowed to add your certificate for your custom domain name. You can find the documentation of the feature here: http://doc.appsdeck.eu/app/ssl
When you add a certificate, the change is done instantly, just start using your domain using
https://, and your requests will be correctly encrypted using your X509 certificate and RSA key pair.
