Transport Layer Security and its predecessor Secure Sockets Layer (SSL) are protocols for securing exchanges over computer networks, particularly the Internet. [Source Wikipedia]
SSL creates a secure channel between your computer and the website you are visiting via your web browser. If in the address bar of your browser you see a padlock and a url address in the form HTTPS then the connection is secure. Your transactions and the confidentiality of your information are protected and secure. It is then theoretically impossible for criminals or hackers to consult or falsify your exchanges.
Although a new protocol (TLS) has now emerged to enhance security, for practical reasons the acronym SSL continues to be used.
The SSL certificate is important to secure your identifiers, passwords, banking information (credit card number), addresses, telephone numbers... and in general any confidential information.
Finally, for your SEO, SSL is important because Google favors secure websites in its ranking by giving them a better positioning compared to websites that are not.
It should also be noted that the BlogTheque administration interface is subject to enhanced security with:
- access with a mandatory strong password;
- double authentication (strongly recommended);
- navigation with encrypted URLs.
