X.509 PQC Certificates Assurance

PQC X.509 Assurance

A linting and analysis project for post-quantum certificate structures, path validation assumptions, and compatibility boundaries in X.509 ecosystems.

2026
Security analysis

Problem

Post-quantum certificates stress infrastructure that was tuned for smaller keys, older assumptions, and narrower interoperability profiles.

Technical record

The project treats X.509 as an operational system: parse the certificate, inspect the chain, test the boundary, and record where software expectations diverge from new cryptographic material.

Evidence

The assurance layer records parser behavior, validator decisions, and regression cases under PQC certificate structures.

Stack

  • Certificate parsing and linting
  • Chain validation experiments
  • PQC algorithm metadata
  • Regression-oriented test cases
