Skill UI

Master the creation of a two-tier Public Key Infrastructure (PKI) Certificate Authority hierarchy—including an offline Root CA and an operational Intermediate CA. This skill guides you through using OpenSSL and Python cryptography to manage X.509 certificate issuance, configure Certificate Revocation Lists (CRLs), set up OCSP responders, and enforce strict certificate policies. Essential for deploying robust trust anchors for TLS, code signing, or client authentication.

repo-scan is a powerful tool designed to audit large, complex, cross-stack codebases (C++, Java, iOS, Web). It classifies every file into project code, third-party dependencies, or build artifacts. Key features include detecting embedded libraries (e.g., FFmpeg, OpenSSL) and providing a practical 4-stage assessment (Core Asset / Extract / Refactor / Deprecate) via an interactive HTML report. Essential for managing monorepos and planning major refactoring efforts.
