API Gateway Proxy SSL

Understanding SSL/TLS for API Gateway Proxy

SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are essential protocols for securing communications between clients and your API gateway. This guide covers everything you need to implement robust encryption for your AI API infrastructure.

# Nginx SSL Configuration for API Gateway Proxy
server {
    listen 443 ssl http2;
    server_name api.yourdomain.com;
    
    # SSL Certificate Paths
    ssl_certificate /etc/ssl/certs/api-gateway.crt;
    ssl_certificate_key /etc/ssl/private/api-gateway.key;
    
    # Modern TLS Configuration
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256;
    ssl_prefer_server_ciphers off;
    
    # OCSP Stapling
    ssl_stapling on;
    ssl_stapling_verify on;
    
    # Performance
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 1d;
    
    # Proxy to Backend
    location / {
        proxy_pass http://backend:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Key Benefits

• Data Privacy — Prevent eavesdropping and man-in-the-middle attacks on your AI API traffic
• Authentication — Verify the identity of your API gateway to clients and backends
• Compliance — Meet security requirements for GDPR, HIPAA, and PCI-DSS
• Trust — Display secure padlock symbol to build user confidence
