Valid Certificate and Certificate Chain
This certificate is valid and has a valid certificate chain, meanubg the certificate has been issued by a trusted Certificate Authority (CA) and is considered reliable. SSL certificates are used to secure websites, and their validity is crucial for data encryption and user trust. The certificate chain consists of the server's certificate, intermediate certificates, and a root CA certificate. Browsers validate this chain to ensure that the website's identity has been verified and that data transmission is secure. In essence, a valid SSL certificate with a valid certificate chain ensures encrypted and trustworthy communication between users and the website.
SSL/TLS certificates are digital certificates used to secure communication between web browsers and servers on the World Wide Web.
