selfsigned CA / server cert. cheat sheet (people regularly ask me for this)

create your own CA and server certificate

Note that the common name of the server certificate has to match your hostname!

magic oneliner:

openssl req -new -x509 -keyout privkey.pem -out cacert.pem -days 1095 -nodes -newkey rsa:<keysize> -sha256
