How do I troubleshoot certificate validation errors?

The skill includes a comprehensive debugging section with OpenSSL commands to check certificate expiry, verify chains, and match private keys.

Is there support for local development environments?

Yes, it guides you through using mkcert to generate locally-trusted certificates, ensuring your development environment matches production security.

Does it support mutual TLS (mTLS) for microservices?

Absolutely. It includes implementation patterns and configuration examples for Nginx and service meshes to enable mutual authentication between services.

Does it follow modern security standards like TLS 1.3?

Yes, the skill enforces best practices including TLS 1.3 protocol versions, Perfect Forward Secrecy (PFS), and HSTS configuration.

Can this skill help with Let's Encrypt automation?

Yes, it provides detailed workflows for automating Let's Encrypt certificates using Certbot for standalone servers and cert-manager for Kubernetes clusters.

セキュリティとテスト

Configures TLS certificates and encryption protocols to secure web applications and service-to-service communications.

概要

This skill provides comprehensive guidance for implementing Transport Layer Security (TLS) across various environments, from local development to production Kubernetes clusters. It automates the generation and management of certificates using tools like Let's Encrypt, mkcert, and Vault, while ensuring adherence to TLS 1.3 best practices. It is an essential resource for developers setting up HTTPS, implementing zero-trust mutual TLS (mTLS) for microservices, or troubleshooting complex certificate validation and handshake errors.
