Installing free SSL of Let’s Encrypt is now got simpler with some websites like zerossl or gethttpsforfree
Also cPanel inc have included a plugin to activate Let's Encrypt free SSL. I asked my webhosting service provider to add Let's encrypt free SSL in their cPanel & they added it within 24 hours. Now I'm using SSL or https of Let's encrypt for free.
Generate free SSL on websites I have mentioned, if your hosting provider won't add the plugin to cPanel.
Anyone here using this open Certificate Authority for SSL? Please let me know in comments.
