That's just the way the software built. For browsers, each browser has a CA from various authorities and you add an intermediate key signed by one of those authorities (e.g. Verisign which costs $2000) to the browser to allow you to access a specific domain through a wildcard cert. My K/V software didn't support that. Look at how CentOS 6 stores it's certs in /etc/pki. I think where you'd put your CA + client key bundle. Which means you have to do this for all machines that run your code. That's not optimal or at all portable. You'll probably have to deliver the app as a VM or a docker container to put it all together. Good luck. -- https://mail.python.org/mailman/listinfo/python-list
