       | Hey HN, I built this after years of dealing with SSL certificate
       | surprises - expired certs on subdomains nobody knew existed,
       | shadow IT spinning up certs, the usual 3am outages.
       | 
       | CertRadar has four free tools (no signup, no premium tier):
       | 
       | - CT Log Search - find every certificate ever issued for a domain
       | via Certificate Transparency logs. Great for discovering
       | forgotten subdomains.
       | 
       | - SSL Analyzer - cert chain, TLS versions, HSTS, expiration.
       | Faster than SSL Labs.
       | 
       | - DNS + SSL Check - DNS records and SSL health in one view.
       | 
       | - Security Headers - HSTS, CSP, X-Frame-Options analysis with
       | recommendations.
       | 
       | Built with Rust on GCP Cloud Run. Happy to talk about the
       | architecture or any feedback on what would make these more
       | useful.

       | This is really cool. I've gone down the rabbit hole of
       | Certificate Transparency to find out how crt.sh gets its
       | information - first time I've even heard that it exists. Also,
       | much better UI than crt.sh. I've tried to go over the information
       | there, but it looks really cumbersome.
