Getting Chrome to accept self-signed localhost certificate

Question

I have created a self-signed SSL certificate for the localhost CN. Firefox accepts this certificate after initially complaining about it, as expected. Chrome and IE, however

Answer 1

This post is already flooded with responses, but I created a bash script based on some of the other answers to make it easier to generate a self-signed TLS certificate valid in Chrome (Tested in Chrome 65.x). Hope it's useful to others.

self-signed-tls bash script

After you install (and trust) the certificate, don't forget to restart Chrome (chrome://restart)
