Analyze a website's SSL/TLS certificate to verify expiration dates, validity, and authority details.
SSL (Secure Sockets Layer) certificates secure connection requests between clients and servers. This tool inspects the domain's TLS handshake configuration, parses the public certificate details, and checks expiration states.
Expired or invalid SSL certificates cause web browsers to display prominent "Your connection is not private" warning screens, which blocks visitors, decreases user trust, and hurts SEO rankings. Keeping certificates active is vital for server security and brand reputation.
