System Documentation

What problem does it solve?

Certificate analysis and validation can be tedious and error-prone; cert-parse automates extraction of Subject, Issuer, SANs, validity, and extensions from PEM/DER inputs and helps verify chain integrity.

Core Features & Use Cases

  • Parse Subject, Issuer, SAN, validity, and public key info from certificates (PEM/DER or remote host).
  • Verify certificate chains against a CA bundle and report common issues (expired, self-signed, weak keys).
  • Use Case: Debug TLS deployments by quickly validating server certificates and chain integrity.

Quick Start

Run cert-parse on a PEM file or remote host to extract and verify certificate details.
