Are you ready for a better security with no performance penalty? Are you ready for a performance bump that can take you places in search engine land? In other words: now that HTTP/2 reached production-grade maturity, nothing should hold you back.
The IoT revolution will make sure that only the paranoid survive.
Confused about SSL/TLS certificates? Here is a quick and dirty introduction to SSL/TLS encryption.
In a post titled How to Set Up Letsencrypt, the SSL-Certificate Engine for the Cloud Era of Hyperscale, on AWS EC2, we have introduced you to this free, open, and fully automated Certificate Authority backed by the likes of Facebook (a gold sponsor), and discussed a manual setup for adventurers in How to Use Letsencrypt across Servers in the Manual Configuration Mode with a CSR.
Now is the time to discuss how to extend the validity of a Letsencrypt certificate for up to another 90 days of blissful happiness.
[updated 2018-06-12] As browser makers continue their push for HTTPS and mobile applications are becoming the target of MITM (man-in-the-middle) attacks, cloud developers and administrators are scrambling to find affordable SSL certificates that can live up to the demands of the cloud era. Enter Let’s Encrypt, a new Certificate Authority that is open, fully automated, and free to use, with an almost unprecedented, generous allotment of 100 host names per certificate. Let’s Encrypt delivers on the promise of a worry-free, fully encrypted web 3.0. Cloud Insidr lifts the veil off of Let’s Encrypt’s setup, configuration, its few surprises and hidden gems.
Generating SSL certificates when Letsencrypt (what is Letsencrypt, who is behind it, and how the heck can you get started) is available for your system works in a breeze, but what if you need your certificates for a machine that won’t take Letsencrypt (for whatever reason)? It is still possible: you can either grab Letsencrypt from Git, or, for reasons of practicality… create a certificate signing request (CSR) on your target server, transfer it to your letsencrypt instance, generate the certificates you need, then transfer the generated files back to your target instance and install the certificates in your software.
