SSL Extractor

The SSL Extractor retrieves TLS certificate data for a given domain and presents it in a machine-readable format to support automation and audits. It connects to the domain via TLS, gathers the certificate chain, and parses fields such as subject, issuer, validity dates, SANs, and chain depth. The tool is designed for developers, security engineers, and operations teams needing verifiable cryptographic metadata without manual inspection. Conceptually, it treats certificates as determinable assets: the output includes timestamps in UTC, a SHA-256 fingerprint, and flags for expiry risk, enabling teams to automate renewal workflows and compliance checks. Unique value lies in consistent, structured outputs that integrate with CI/CD pipelines and monitoring stacks, plus optional batch processing for multiple domains and export formats (JSON, CSV, YAML). Use cases include pre-deployment certificate validation, security posture audits, and migration readiness assessments. Core features cover domain input, TLS handshake, certificate parsing, output of issuer, subject, validity window, SANs, chain depth, and expiry indicators; optional features include OCSP/CRL status and multi-domain batch mode.
