What is: SSL

SSL is an abbreviation used for Secure Sockets Layers, an encryption technology that keeps sensitive data between web servers and web browsers secure and private.

SSL may also be called TLS or Transport Layer Security protocol. These protocols rely on certificates that provide an assurance to the user about the identity of the website they are communicating with.

Once you enable SSL, your website will use HTTPS instead of HTTP, and you will also see a padlock sign next to your website address in the browser to show that it is secure.

What is SSL

Should I Use SSL on My Website?

We recommend that all WordPress websites use SSL. It’s one of the best practices listed in our ultimate security guide.

You should be aware that Google Chrome and other web browsers show non-SSL websites as ‘Not Secure’. This means that if you are not using an SSL certificate on your website, then you can lose your customers’ trust.

As a website visitor, you should proceed with extreme caution on websites that have a ‘Not Secure’ label. We recommend that you don’t give them any personal information.

Sites that use SSL will display a padlock icon in the address bar. Users can click on this icon to view certification, identification and other information about a website.

Websites requiring personal data must have an active SSL certificate installed from a recognized Certificate Authority (CA). That includes WordPress users operating an eCommerce site, membership site, or any type of website that requires a user to either submit a payment or login information.

How Does SSL Work?

SSL protects user information by encrypting the data being exchanged between the web server and a visitor’s browser.

When visiting a website, your browser will automatically check for an SSL certificate and to see if it is valid and up to date.

If a website’s certificate is correct, then the browser then uses the website’s public key to encrypt the data. They then send this data back to the designated website’s server where it is decrypted using both the public key and a secret private key.

How SSL works to protect data transfer

If the certificate is not correct, then users will be warned that the connection is not private. It is important that site owners fix this error as soon as possible so that they don’t lose traffic.
