Using encrypted connections to move personal information on the internet is a given, at least it should be. That’s why the Internet Security Research Group (ISRG) provides the free Certificate Authority (CA), Let’s Encrypt.
Digital certificates are provided to enable HTTPS (SSL/TLS) for websites. This ensures that information moving around the world wide web is kept private between users. Everything from email messages to your banking information should be kept confidential when it moves across the internet, and that’s what digital certificates ensure is happening when you use a secured website. Certificate Authorities provide digital certificates that are registered with web browsers to verify and encrypt the information that is sent between users and websites, providing users with the confidence and trust required to use online services.
