About This Tool

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.

How to Use

Provide inputs: domain_name, and optional port and timeout.
Start the extraction: perform the TLS handshake to fetch the certificate chain.
Review outputs: inspect issuer, validity period, SANs, and chain depth.
Assess expiry risk: check days_to_expiry and is_expiring_soon flags.
Export results: save in JSON, CSV, or YAML for automation.

Frequently Asked Questions

Find Quick Answers

What data does SSL Extractor provide?

It returns certificate_subject, issuer, validity_start, validity_end, SANs, chain_depth, sha256_fingerprint, expiration_days, is_expiring_soon, and hostname_matches_domain. The data is suitable for automated checks, compliance reporting, and renewal planning.

Can it handle multiple domains in a single run?

Yes. In batch mode, the tool processes a list of domains and returns an array of domain-specific results, enabling bulk audits and centralized reporting for security and operations teams.

How is expiry risk indicated?

The tool computes days_to_expiry and sets is_expiring_soon based on configurable thresholds. This helps automate renewal alerts and integration with monitoring systems for proactive certificate management.

Are export formats customizable?

JSON is provided by default; advanced usage can export to CSV or YAML. This supports integration with logs, dashboards, and configuration management workflows.
