A script to generate a self-signed certificate with a random passphrase, for getting a test server up quickly.
For baffling reasons, the security world seems to feel it's an asset that creating a self-signed certificate is a cryptic, multi-step process involving a bunch of incantations and intermediate files - when most of the time you're just creating a self-signed cert for a web server, and if you want an actual trusted certificate, you're buying that from a third-party.
This script simply generates self-signed key and certificate file in one step, passing the domain on the command-line.
Requires NodeJS, OpenSSL, and a pre-existing
temporary folder at /tmp.
