CA Certificates Test Server

A Node.js HTTPS test server with self-signed certificate generation for testing SSL/TLS connections in Bruno.

Overview

This server provides two main functionalities:

1. Certificate Generation - Creates a complete CA certificate chain for testing
2. HTTPS Server - Runs a secure server using the generated certificates

Usage

1. Generate Certificates

Generate the required CA certificates and add them to your system's truststore:

node scripts/generate-certs.js

This will:

• Create a certs/ directory
• Generate CA certificate, server certificate, and private keys
• Verify the certificate chain
• Add the CA certificate to your system's truststore (macOS/Linux/Windows)

Generated Files:

• certs/ca-cert.pem - Certificate Authority certificate
• certs/ca-key.pem - CA private key
• certs/localhost-cert.pem - Server certificate for localhost
• certs/localhost-key.pem - Server private key

Windows-Specific Files (automatically generated on Windows):

• certs/ca-cert.der - CA certificate in DER format (for Windows certificate store)
• certs/localhost.p12 - PKCS#12 bundle containing server certificate and key
• certs/localhost-cert.der - Server certificate in DER format

Certificate Installation Details

The certificate generation script automatically adds the CA certificate to your system's truststore:

macOS: Uses security add-trusted-cert to add the CA to the System keychain Linux: Copies the CA certificate to /usr/local/share/ca-certificates/ and runs update-ca-certificates Windows: Uses PowerShell to add the CA certificate to the LocalMachine\Root certificate store

Note: On Windows, the script requires Administrator privileges to install certificates to the machine-wide certificate store. If you encounter permission issues, run your terminal as Administrator.

2. Run HTTPS Server

Start the HTTPS server on port 8090:

node index.js

The server will:

• Load certificates from the certs/ directory
• Start an HTTPS server on https://localhost:8090
• Serve a simple "helloworld" response
• Handle graceful shutdown on SIGINT/SIGTERM

Testing

Once the server is running, you can test SSL connections:

Unix/Linux/macOS

# Test with curl
curl https://localhost:8090

# Test certificate verification
openssl s_client -connect localhost:8090 -CAfile certs/ca-cert.pem

Windows

# Test with curl (if available)
curl https://localhost:8090

# Test with PowerShell Invoke-WebRequest
Invoke-WebRequest -Uri https://localhost:8090

# Test certificate verification with OpenSSL
openssl s_client -connect localhost:8090 -CAfile certs/ca-cert.pem

# Verify certificate is installed in Windows certificate store
Get-ChildItem -Path Cert:\LocalMachine\Root | Where-Object { $_.Subject -like "*Local Dev CA*" }

# Test with .NET WebClient (alternative method)
$client = New-Object System.Net.WebClient
$client.DownloadString("https://localhost:8090")
