How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

uint16_t udp_checksum(struct udphdr *p_udp_header, size_t len, uint32_t src_addr, uint32_t dest_addr)
{
  const uint16_t *buf = (const uint16_t*)p_udp_header;
  uint16_t *ip_src = (void*)&src_addr, *ip_dst = (void*)&dest_addr;
  uint32_t sum;
  size_t length = len;

  // Calculate the sum
  sum = 0;
  while (len > 1)

Where $ip and $port are your MSI Afterburner Remote Server's IP address and port:

• Go to $ip:$port/mahm, you will be presented with a HTTP Basic Auth dialog.
• Enter MSIAfterburner as the username.
• Enter your security key as the password.

Profit! You'll get an XML file that looks something like the attached xml-example.xml.

How to setup Let's Encrypt for Nginx on Ubuntu 16.04 (including IPv6, HTTP/2 and A+ SLL rating)

There are two main modes to run the Let's Encrypt client (called Certbot):

• Standalone: replaces the webserver to respond to ACME challenges
• Webroot: needs your webserver to serve challenges from a known folder.

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.
