Google’s move to mark http sites as “not secure” prompted me to activate an SSL certificate a few weeks ago. In October 2018, Google will show a red not secure* warning on HTTP pages that ask users to enter data.
No need to panic, free certificates are available through Let’s Encrypt to enable HTTPS. Let’s Encrypt, @letsencrypt, are a certificate authority (CA) that provide trusted certificates for free in order to implement best practices for TLS, transport layer security. NB: people may still use the term SSL, secure socket layers, even though they have upgraded to TLS.
Geeks can try Let’s Encrypt How It Works to understand the details .
