OpenSSL Self-Signed Certificate Creation

This skill provides guidance for creating self-signed SSL/TLS certificates using OpenSSL command-line tools, including proper verification and scripting approaches.

Core Workflow

Step 1: Create Directory Structure

Establish the output directory before generating any files:

mkdir -p /path/to/certs

Step 2: Generate Private Key

Generate an RSA private key (2048-bit minimum, 4096-bit recommended for production):
