2017-06-23 : 02:41
DNS challenges from Lets Encrypt make the verification process easier and you can fully automate the process with the Rackspace Cloud DNS API.
If you are not familiar with how Let’s Encrypt operates, here is an extremely simple explanation:
- Create a private key
- Make a request for a new certificate
- Complete the challenge process
- You have a certificate!
That is highly simplified, but there is plenty of detail available on how the whole system works.
One of the most popular challenge methods is HTTP. That involves getting a challenge string from Let’s Encrypt, placing the string at a known URL on your domain, and then waiting for verification of the challenge. The process is quick and Let’s Encrypt provides tools that automate much of the process for you.
