HTTPS Certificate Checker
HTTPS (short for Hypertext Transfer Protocol Secure) is a communication protocol that is intended to transfer data securely on the World Wide Web by means of encryption. With the help of certificates, the authentication of the server and the domain of a website is guaranteed and classified as secure. Nevertheless, HTTPS certificates are limited in time. They are regularly checked by browsers and rejected if they are insecure or outdated.
