About this skill

What it does

This skill checks the validity and details of HTTPS certificates for a given domain. It retrieves certificate information such as expiration dates, issuer, and subject names. This allows you to verify if a website's security is up-to-date and identify potential issues with its SSL/TLS configuration.

When to use it

  • Security Audits: Quickly assess the HTTPS certificates of websites during routine security checks.
  • Troubleshooting Website Errors: Diagnose errors related to expired or invalid SSL/TLS certificates, which can cause connection problems.
  • Verifying Certificate Details: Confirm specific details about a certificate (e.g., expiration date) for compliance or verification purposes.
  • Automated Monitoring: Integrate into scripts to automatically monitor the validity of certificates and alert on potential expirations.

Key capabilities

  • Retrieves HTTPS certificate information.
  • Checks certificate validity.
  • Provides details like issuer, subject, and expiration date.

Example prompts

  • "Check the SSL certificate for example.com."
  • "What is the expiration date of the certificate for google.com?"
  • "Is the HTTPS certificate for mywebsite.net valid?"

Tips & gotchas

The skill requires an internet connection to retrieve certificate information. Results are only as reliable as the publicly available certificate data.
