Only HTTPS URLs are supported for SSL certificate checking

This tool analyzes SSL/TLS certificates and provides comprehensive security information including:

Certificate Validity: Checks if the certificate is valid and trusted
Security Protocols: Identifies TLS version and cipher suites used
Expiration Monitoring: Shows certificate validity period and expiration warnings
Security Assessment: Provides an overall security rating based on current best practices
