Enable SSL in Apache (OSX)

The following will guide you through the process of enabling SSL on a Apache webserver

• The instructions have been verified with OSX El Capitan (10.11.2) running Apache 2.4.16
• The instructions assume you already have a basic Apache configuration enabled on OSX, if this is not the case feel free to consult Gist: "Enable Apache HTTP server (OSX)"

Apache SSL Configuration

Create a directory within /etc/apache2/ using Terminal.app: sudo mkdir /etc/apache2/ssl
Next, generate two host keys:

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

With the release of Vivaldi 2.2, this page is now obsolete and unmaintained. Widevine is fetched automatically on post install of our official packages. The information below and the script are left for historical reasons but will not be updated.

If you are using something newer than Vivaldi 2.2, you should not be using this script as there is simply no need. Any need you think you have for it would be a bug IMHO and thus should be logged in a bug report. Before you do so however, you should also checkout the Vivaldi help page on Widevine, on Linux

A bunch of people asked how they could use this script with pure Chromium on Ubuntu. The following is a quick guide. Though I still suggest you at least try Vivaldi. Who knows, you might like it. Worried about proprietary componants? Remember that libwidevinecdm.so is a b
