Client-side SSL

For excessively paranoid client authentication.

Using self-signed certificate.

Create a Certificate Authority root (which represents this server)

Organization & Common Name: Some human identifier for this server CA.

openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt

Java uses static, declared typing:

String hello = "Hello, World!";
List<String> phrases = new ArrayList<String>;
phrases.add(hello);
phrases.add(null);
phrases.add(123); // Compile error! Not a string.
