Generates a self-signed certificate for HTTPS testing.
$ mix phx.gen.cert
$ mix phx.gen.cert my-app my-app.local my-app.internal.example.com
Creates a private key and a self-signed certificate in PEM format. These
files can be referenced in the certfile and keyfile parameters of an
HTTPS Endpoint.
WARNING: only use the generated certificate for testing in a closed network
environment, such as running a development server on localhost.
For production, staging, or testing servers on the public internet, obtain a
proper certificate, for example from Let's Encrypt.
NOTE: when using Google Chrome, open chrome://flags/#allow-insecure-localhost
to enable the use of self-signed certificates on localhost.
