What is the SSL/TLS Handshake Auditor?
A deep cryptographic chain analyzer that extracts X.509 certificates and simulates cipher suite negotiations to preemptively identify downgrade vulnerabilities.
How it Works under the hood
Instead of relying on browser states, the Node.js backend establishes raw TLS sockets against port 443. It enumerates the entire Certificate Authority (CA) signature chain, tests for obsolete protocol support (like TLS 1.0 or 1.1), and decodes Subject Alternative Names.
SysAdmin & Security Use Cases
- »Audit web servers for compliance against modern cryptographic standards.
- »Detect expiring SSL certificates before they trigger browser warnings.
- »Map out hidden subdomains via Alternative Name analysis.
- »Prevent MITM downgrade attacks by validating secure Cipher Suites.
