+# π Security Improvements
+
+## Implemented Security Features
+
+### 1. n8n API Endpoint Protection
+
+All n8n endpoints are now protected with:
+- **Authentication**: Admin authentication required for sensitive endpoints (`/api/n8n/generate-image`)
+- **Rate Limiting**:
+ - `/api/n8n/generate-image`: 10 requests/minute
+ - `/api/n8n/chat`: 20 requests/minute
+ - `/api/n8n/status`: 30 requests/minute
+
+### 2. Email Obfuscation
+
+Email addresses can now be obfuscated to prevent automated scraping:
+
+```typescript
+import { createObfuscatedMailto } from '@/lib/email-obfuscate';
+import { ObfuscatedEmail } from '@/components/ObfuscatedEmail';
+
+// React component
+Contact Me
+
+// HTML string
+const mailtoLink = createObfuscatedMailto('contact@dk0.dev', 'Email Me');
+```
+
+**How it works:**
+- Emails are base64 encoded in the HTML
+- JavaScript decodes them on click
+- Prevents simple regex-based email scrapers
+- Still functional for real users
+
+### 3. URL Obfuscation
+
+Sensitive URLs can be obfuscated:
+
+```typescript
+import { createObfuscatedLink } from '@/lib/email-obfuscate';
+
+const link = createObfuscatedLink('https://sensitive-url.com', 'Click Here');
+```
+
+### 4. Rate Limiting
+
+All API endpoints have rate limiting:
+- Prevents brute force attacks
+- Protects against DDoS
+- Configurable per endpoint
+
+## Code Obfuscation
+
+**Note**: Full code obfuscation for Next.js is **not recommended** because:
+
+1. **Next.js already minifies code** in production builds
+2. **Obfuscation breaks source maps** (harder to debug)
+3. **Performance impact** (slower execution)
+4. **Not effective** - determined attackers can still reverse engineer
+5. **Maintenance burden** - harder to debug issues
+
+**Better alternatives:**
+- β
Minification (already enabled in Next.js)
+- β
Environment variables for secrets
+- β
Server-side rendering (code not exposed)
+- β
API authentication
+- β
Rate limiting
+- β
Security headers
+
+## Best Practices
+
+### For Email Protection:
+1. Use obfuscated emails in public HTML
+2. Use contact forms instead of direct mailto links
+3. Monitor for spam patterns
+
+### For API Protection:
+1. Always require authentication for sensitive endpoints
+2. Use rate limiting
+3. Log suspicious activity
+4. Use HTTPS only
+5. Validate all inputs
+
+### For Webhook Protection:
+1. Use secret tokens (`N8N_SECRET_TOKEN`)
+2. Verify webhook signatures
+3. Rate limit webhook endpoints
+4. Monitor webhook usage
+
+## Implementation Status
+
+- β
n8n endpoints protected with auth + rate limiting
+- β
Email obfuscation utility created
+- β
URL obfuscation utility created
+- β
Rate limiting on all n8n endpoints
+- β οΈ Email obfuscation not yet applied to pages (manual step)
+- β οΈ Code obfuscation not implemented (not recommended)
+
+## Next Steps
+
+To apply email obfuscation to your pages:
+
+1. Import the utility:
+```typescript
+import { ObfuscatedEmail } from '@/lib/email-obfuscate';
+```
+
+2. Replace email links:
+```tsx
+// Before
+Contact
+
+// After
+Contact
+```
+
+3. For static HTML, use the string function:
+```typescript
+const html = createObfuscatedMailto('contact@dk0.dev', 'Email Me');
+```
