SSL/TLS Certificate Configuration Guide 🛡️

Introduction

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) certificates are essential for encrypting data transmissions between clients and servers. This guide provides step-by-step instructions for configuring SSL/TLS certificates on your server.

Steps to Configure SSL/TLS Certificates

  1. Generate Certificate Signing Request (CSR)
    Use OpenSSL to create a CSR file, which includes your server's public key and details. 

    openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr

    ✅ Include your domain name and organizational information during this process.

  2. Obtain SSL/TLS Certificate
    Submit the CSR to a trusted Certificate Authority (CA) to get your certificate.

  3. Install Certificate on Server
    Place the certificate and private key files in your server's configuration directory.
    📁 Example: /etc/ssl/certs/ or /usr/local/etc/

  4. Configure Server Software
    Update your web server (e.g., Nginx, Apache) configuration to use the certificate.
    🔧 Example for Nginx:

    ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/privkey.pem;

  5. Test Configuration
    Use tools like openssl s_client -connect yourdomain.com:443 to verify the setup.
    🧪 Ensure no errors are returned and the connection is encrypted.

Tips

  • 🔒 Always use strong encryption protocols (e.g., TLS 1.2 or higher).
  • 📈 Regularly update your certificates before they expire.
  • 📖 For detailed troubleshooting, refer to SSL/TLS Troubleshooting Guide.
