The Qualys SSL Server tool is an excellent free tool that grades the quality of your SSL configuration that also identifies any areas that need to be addressed.
Using an SSL certificate is a must for ensuring your website is protected and meets the demands of today's modern sites/browsers. Customers and visitors to your site will know that their browsing session is safe, and that payment details and personal information is secure and encrypted in transit.
The following guide creates a certificate through Apache and a trusted certificate authority, applying the certificate to your website then forcing all traffic to use HTTPS rather than HTTP.
