SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires opencert.py, validatepair.py, cryptography, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill simplifies the complex process of verifying the authenticity and integrity of digital certificates and cryptographic keys used in X9.150 secure payment systems, preventing fraudulent transactions.

Core Features & Use Cases

  • Certificate Chain Analysis: Deep inspection of JWKS files, detailing subject, issuer, validity, fingerprints, and chain linkage.
  • Key Pair Validation: Verifies private key and public certificate pairs through signing, verification, and tamper tests.
  • Use Case: A developer integrating with an X9.150 payment gateway can use this Skill to quickly diagnose why a certificate is not being accepted, checking for expiration, incorrect key usage, or chain breaks.

Quick Start

Use the x9-inspect-cert skill to inspect the certificate chain in the payee_db/certs/payee.jwks file.

Frequently Asked Questions about x9-inspect-cert

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate a JWKS certificate chain for X9.150 payment systems?▼

You validate a JWKS certificate chain by inspecting subject, issuer, validity, fingerprints, and chain linkage. The Skill checks thumbprint matching and chain integrity to prevent fraudulent transactions in X9.150 secure payment systems.

Why does my X9.150 certificate get rejected by the payment gateway?▼

Your X9.150 certificate may be rejected due to expiration, incorrect key usage, or chain breaks. Deep inspection of JWKS files and key pair validation through signing, verification, and tamper tests pinpoints the specific integrity or authenticity failure.

Can I verify private key and public certificate pairs using Python cryptography?▼

Yes, you can verify private key and public certificate pairs using Python cryptography utilities. The process performs signing, verification, and tamper resistance tests to confirm the key pair matches correctly for secure X9.150 implementations.

What is the best way to inspect payee and payer certificate chains in JWKS format?▼

Inspect payee and payer certificate chains in JWKS format by running Python utilities that detail certificate properties and verify thumbprint matching. This validates chain linkage and tamper resistance for both payer and payee X9.150 certificate implementations.

Does validating X9.150 key pairs require checking tamper resistance?▼

Validating X9.150 key pairs requires checking tamper resistance to guarantee security. The validation process runs signing, verification, and tamper tests to ensure the private key and public certificate pair resists fraudulent modifications.
