ssl-certificate-checker

To check an SSL certificate, this Skill uses openssl s_client to retrieve and analyze certificate details including validity, expiry, issuer, subject, and chain of trust status for remote hosts.

Yes, you can inspect SSL certificates using STARTTLS protocols. The Skill supports both direct TLS and STARTTLS connections, allowing you to evaluate certificate validity and chain of trust across different protocol setups.

To verify the chain of trust for a TLS certificate, the Skill checks if the certificate chain is trusted by the system's CA bundle. This ensures the connection is secured by a trusted authority rather than a self-signed certificate.

When inspecting a self-signed SSL certificate, the Skill applies robust error handling to manage the connection. It identifies that the certificate is not trusted by the system's CA bundle and reports the chain of trust status accordingly.

Yes, the SSL certificate checker shows Subject Alternative Names (SANs) along with the certificate's issuer, subject, validity, and expiry. This provides a comprehensive view of the domains covered by the TLS certificate.

You need to inspect SSL certificates before connecting to a service to prevent potential security risks. Verifying validity, expiry, and trusted issuance ensures your connection to sensitive services like financial platforms remains secure.
