HTTPS, or “secure http”, was developed to allow authorization and secured transactions. Exchanging confidential information needs to be secured in order to prevent unauthorized access, and https makes this happen. In many ways, https is identical to http because it follows the same basic protocols. The http or https client, such as a Web browser, establishes a connection to a server on a standard port. However, https offers an extra layer of security because it uses SSL to move data.
How to switch with WordPress.
I recently purchase a certificate with my host provider. I was reluctant to proceed as I did not want to mess up with my configuration.
WordPress makes it easy for you. Indeed, there is probably a plugin for that. I did a search on the plugin repository and I came across Really Simple SSL. Find out more at https://wordpress.org/plugins/really-simple-ssl/ . It has detected my configuration and the entire website was moved to SSL. I couldn’t be easier than that. You can find a commercial version at https://really-simple-ssl.com/premium/ .
