Apache HTTPD inside docker with HTTPS

Testing environment for Java HTTPS protocols tests

Use ./run.sh (the same as ./run.sh localhost 443 'TLSv1 +TLSv1.1 +TLSv1.2') to

• Generate self-signed certificate for localhost.
• Start Apache HTTPD inside docker, accesible through port 443.
• With supported protocols set to TLS v1.0, 1.1 and 1.2.
• Create truststore.jks keystore with the self-signed certificate imported and trusted.

Can be later used/tested from java as:

(cat >client.java <<"EOF"
  public class client {
      public static void main(String[] args) throws Exception {
          String url = args.length > 0 ? args[0] : "https://localhost";
          try (java.io.BufferedReader reader = new java.io.BufferedReader(new java.io.InputStreamReader(new java.net.URL(url).openConnection().getInputStream()))){
              reader.lines().forEach(System.out::println);
          }
      }
  }
EOF
