Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.
