SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps security professionals inspect TLS endpoints and cryptographic artifacts without manually interpreting complex certificate, key, signature, or protocol data.

Core Features & Use Cases

  • TLS Inspection: Examine authorized TLS endpoints, certificate chains, handshake details, and protocol evidence.
  • Cryptographic Artifact Analysis: Inspect certificates, CSRs, public keys, digests, signatures, and encoded data.
  • Evidence-Focused Verification: Capture relevant outputs, identify validity and verification errors, and avoid overstating cryptographic impact during security reviews.

Quick Start

Use the openssl skill to inspect the certificate chain and validity details for the authorized TLS endpoint provided.

FAQPage Schema
How do I inspect a TLS certificate chain and verify its validity?

To inspect a TLS certificate chain, you examine the authorized TLS endpoints to identify certificate validity, issuer, subject, fingerprint, and any verification errors. This process captures handshake details and protocol evidence while preserving the cryptographic material for security reviews.

What is the best way to analyze cryptographic artifacts like CSRs and public keys?

Analyzing cryptographic artifacts involves inspecting certificates, CSRs, public keys, digests, signatures, and encoded data to identify their encoding and verification details. This approach ensures you capture relevant outputs without overstating the cryptographic impact during security reviews.

Can I use this for authorized penetration testing and security research?

Yes, you can use this for authorized penetration testing, certificate assessment, cryptographic material review, and security research involving provided artifacts or in-scope endpoints. It requires help-driven command selection to safely handle sensitive data and preserve evidence.

How do I identify verification errors when reviewing TLS endpoints?

To identify verification errors when reviewing TLS endpoints, you apply evidence-focused inspection to explicitly report validity, issuer, subject, and fingerprint details. This method captures protocol evidence and highlights verification failures during the security assessment.

What are the limitations of inspecting cryptographic signatures and encoded data?

A limitation of inspecting cryptographic signatures and encoded data is the need to avoid overstating cryptographic impact. It requires careful sensitive-data handling and explicit reporting of verification errors rather than making broad security claims about the artifacts.
