SSL (Secure Sockets Layer) is a protocol that encrypts your data as it travels between your computer and the web server. This helps protect your information from being intercepted by unauthorized individuals. In order to use SSL, you will need to have a certificate from a certified SSL provider.
The cost of this service can vary, but is usually quite reasonable. You can find a list of providers here: https://www.ssllabs.com/resources/directory/.
SSL is generally required for any site that collects personal information, such as contact information or credit card numbers. It is also recommended for sites that sell products or services online.
For most blog owners, the benefits of using SSL are not worth the cost of getting a certificate. However, if you have specific concerns about your website’s security, using SSL may be the best option for you.
