Web Server

Installing a free SSL certificate is an important part of running a web server. Without it, traffic would use HTTP rather than HTTPs , which is the secure version . Enable HTTPs to secure both sending and receipt of emails using secured ports. Similarly, both FTP and SSH access can be secured. This is done through a private key file and public key file contained within a certificate signing request or CSR. 

LetsEncrypt SSL Certificates

From September 30 2021, LetsEncrypts’ cross-sign DST Root CA X3 expired. So devices and operating systems that don’t trust the ISRG Root x1 ssl certificate will no longer trust certificates and show “Not secure” warnings. This excludes some android devices that will remain valid for longer. 

Openssl 1.0.2 users must update to at least version 1.1.0 to avoid any issues. More information about this update and its impacts can be found on LetsEncrypts website.
