Managing Certificates with PowerShell: Designing Secure Self-Signed Certificates

Securing local web endpoints and internal APIs with HTTPS is a fundamental requirement for modern development and system administration. If you need to establish secure connections between internal applications on Windows, understanding how to generate and configure self-signed certificates is a critical skill. This text-based course guides you through the foundational concepts of public key cryptography before diving into practical execution using PowerShell. You will learn how to confidently issue, configure, and manage self-signed certificates using native Windows tools. We cover essential security parameters, certificate store architecture, and modern best practices for key usage and signature algorithms. What you'll learn: - Understand foundational certificate terminology, public/private key pairs, and trust chains - Configure the New-SelfSignedCertificate cmdlet using specific parameter options for DNS names, key usage, and friendly names - Secure web API endpoints by binding generated certificates to local ports and web servers - Manage local certificate stores to ensure proper trust relationships between internal services - Apply modern security standards, including strong cryptographic algorithms and appropriate key lengths - Troubleshoot common SSL/TLS handshake errors and trust issues in development environments The course begins with clear explanations of cryptographic concepts and certificate types, then moves step-by-step through command syntax, practical parameter breakdowns, and verification procedures. It is designed specifically for beginners in system administration, DevOps, or backend development who need to secure services without relying on external certificate authorities. No prior security experience is required. Start reading today to secure your internal APIs and services with confidence.
