+# HTTPS/TLS Support
+
+## Overview
+
+AtlasOS supports HTTPS/TLS encryption for secure communication. TLS can be enabled via environment variables, and the system will automatically enforce HTTPS connections when TLS is enabled.
+
+## Configuration
+
+### Environment Variables
+
+TLS is configured via environment variables:
+
+- **`ATLAS_TLS_CERT`**: Path to TLS certificate file (PEM format)
+- **`ATLAS_TLS_KEY`**: Path to TLS private key file (PEM format)
+- **`ATLAS_TLS_ENABLED`**: Force enable TLS (optional, auto-enabled if cert/key provided)
+
+### Automatic Detection
+
+TLS is automatically enabled if both `ATLAS_TLS_CERT` and `ATLAS_TLS_KEY` are set:
+
+```bash
+export ATLAS_TLS_CERT=/etc/atlas/tls/cert.pem
+export ATLAS_TLS_KEY=/etc/atlas/tls/key.pem
+./atlas-api
+```
+
+### Explicit Enable
+
+Force TLS even if cert/key are not set (will fail at startup if cert/key missing):
+
+```bash
+export ATLAS_TLS_ENABLED=true
+export ATLAS_TLS_CERT=/etc/atlas/tls/cert.pem
+export ATLAS_TLS_KEY=/etc/atlas/tls/key.pem
+./atlas-api
+```
+
+## Certificate Requirements
+
+### Certificate Format
+
+- **Format**: PEM (Privacy-Enhanced Mail)
+- **Certificate**: X.509 certificate
+- **Key**: RSA or ECDSA private key
+- **Chain**: Certificate chain can be included in cert file
+
+### Certificate Validation
+
+At startup, the system validates:
+- Certificate file exists
+- Key file exists
+- Certificate and key are valid and match
+- Certificate is not expired (checked by Go's TLS library)
+
+## TLS Configuration
+
+### Supported TLS Versions
+
+- **Minimum**: TLS 1.2
+- **Maximum**: TLS 1.3
+
+### Cipher Suites
+
+The system uses secure cipher suites:
+
+- `TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384`
+- `TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384`
+- `TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305`
+- `TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305`
+- `TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256`
+- `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256`
+
+### Elliptic Curves
+
+Preferred curves:
+- `CurveP256`
+- `CurveP384`
+- `CurveP521`
+- `X25519`
+
+## HTTPS Enforcement
+
+### Automatic Redirect
+
+When TLS is enabled, HTTP requests are automatically redirected to HTTPS:
+
+```
+HTTP Request → 301 Moved Permanently → HTTPS
+```
+
+### Exceptions
+
+HTTPS enforcement is skipped for:
+- **Health checks**: `/healthz`, `/health` (allows monitoring)
+- **Localhost**: Requests from `localhost`, `127.0.0.1`, `::1` (development)
+
+### Reverse Proxy Support
+
+The system respects `X-Forwarded-Proto` header for reverse proxy setups:
+
+```
+X-Forwarded-Proto: https
+```
+
+## Usage Examples
+
+### Development (HTTP)
+
+```bash
+# No TLS configuration - runs on HTTP
+./atlas-api
+```
+
+### Production (HTTPS)
+
+```bash
+# Enable TLS
+export ATLAS_TLS_CERT=/etc/ssl/certs/atlas.crt
+export ATLAS_TLS_KEY=/etc/ssl/private/atlas.key
+export ATLAS_HTTP_ADDR=:8443
+./atlas-api
+```
+
+### Using Let's Encrypt
+
+```bash
+# Let's Encrypt certificates
+export ATLAS_TLS_CERT=/etc/letsencrypt/live/atlas.example.com/fullchain.pem
+export ATLAS_TLS_KEY=/etc/letsencrypt/live/atlas.example.com/privkey.pem
+./atlas-api
+```
+
+### Self-Signed Certificate (Testing)
+
+Generate a self-signed certificate:
+
+```bash
+openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
+```
+
+Use it:
+
+```bash
+export ATLAS_TLS_CERT=./cert.pem
+export ATLAS_TLS_KEY=./key.pem
+./atlas-api
+```
+
+## Security Headers
+
+When TLS is enabled, additional security headers are set:
+
+### HSTS (HTTP Strict Transport Security)
+
+```
+Strict-Transport-Security: max-age=31536000; includeSubDomains
+```
+
+- **Max Age**: 1 year (31536000 seconds)
+- **Include Subdomains**: Yes
+- **Purpose**: Forces browsers to use HTTPS
+
+### Content Security Policy
+
+CSP is configured to work with HTTPS:
+
+```
+Content-Security-Policy: default-src 'self'; ...
+```
+
+## Reverse Proxy Setup
+
+### Nginx
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name atlas.example.com;
+
+    ssl_certificate /etc/ssl/certs/atlas.crt;
+    ssl_certificate_key /etc/ssl/private/atlas.key;
+
+    location / {
+        proxy_pass http://localhost:8080;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+### Apache
+
+```apache
+<VirtualHost *:443>
+    ServerName atlas.example.com
+    
+    SSLEngine on
+    SSLCertificateFile /etc/ssl/certs/atlas.crt
+    SSLCertificateKeyFile /etc/ssl/private/atlas.key
+
+    ProxyPass / http://localhost:8080/
+    ProxyPassReverse / http://localhost:8080/
+    
+    RequestHeader set X-Forwarded-Proto "https"
+</VirtualHost>
+```
+
+## Troubleshooting
+
+### Certificate Not Found
+
+```
+TLS configuration error: TLS certificate file not found: /path/to/cert.pem
+```
+
+**Solution**: Verify certificate file path and permissions.
+
+### Certificate/Key Mismatch
+
+```
+TLS configuration error: load TLS certificate: tls: private key does not match public key
+```
+
+**Solution**: Ensure certificate and key files match.
+
+### Certificate Expired
+
+```
+TLS handshake error: x509: certificate has expired or is not yet valid
+```
+
+**Solution**: Renew certificate or use a valid certificate.
+
+### Port Already in Use
+
+```
+listen tcp :8443: bind: address already in use
+```
+
+**Solution**: Change port or stop conflicting service.
+
+## Best Practices
+
+### 1. Use Valid Certificates
+
+- **Production**: Use certificates from trusted CAs (Let's Encrypt, commercial CAs)
+- **Development**: Self-signed certificates are acceptable
+- **Testing**: Use test certificates with short expiration
+
+### 2. Certificate Renewal
+
+- **Monitor Expiration**: Set up alerts for certificate expiration
+- **Auto-Renewal**: Use tools like `certbot` for Let's Encrypt
+- **Graceful Reload**: Restart service after certificate renewal
+
+### 3. Key Security
+
+- **Permissions**: Restrict key file permissions (`chmod 600`)
+- **Ownership**: Use dedicated user for key file
+- **Storage**: Store keys securely, never commit to version control
+
+### 4. TLS Configuration
+
+- **Minimum Version**: TLS 1.2 or higher
+- **Cipher Suites**: Use strong cipher suites only
+- **HSTS**: Enable HSTS for production
+
+### 5. Reverse Proxy
+
+- **Terminate TLS**: Terminate TLS at reverse proxy for better performance
+- **Forward Headers**: Forward `X-Forwarded-Proto` header
+- **Health Checks**: Allow HTTP for health checks
+
+## Compliance
+
+### SRS Requirement
+
+Per SRS section 5.3 Security:
+- **HTTPS SHALL be enforced for the web UI** ✅
+
+This implementation:
+- ✅ Supports TLS/HTTPS
+- ✅ Enforces HTTPS when TLS is enabled
+- ✅ Provides secure cipher suites
+- ✅ Includes HSTS headers
+- ✅ Validates certificates
+
+## Future Enhancements
+
+1. **Certificate Auto-Renewal**: Automatic certificate renewal
+2. **OCSP Stapling**: Online Certificate Status Protocol stapling
+3. **Certificate Rotation**: Seamless certificate rotation
+4. **TLS 1.4 Support**: Support for future TLS versions
+5. **Client Certificate Authentication**: Mutual TLS (mTLS)
+6. **Certificate Monitoring**: Certificate expiration monitoring

+- `repaired`: Number of errors repaired
+- `last_scrub`: Timestamp of last completed scrub
+
+## Usage Examples
+
+### Import a Pool
+
+```bash
+curl -X POST http://localhost:8080/api/v1/pools/import \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "tank"
+  }'
+```
+
+### Start Scrub and Monitor Progress
+
+```bash
+# Start scrub
+curl -X POST http://localhost:8080/api/v1/pools/tank/scrub \
+  -H "Authorization: Bearer $TOKEN"
+
+# Check progress
+curl http://localhost:8080/api/v1/pools/tank/scrub \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+### Export Pool
+
+```bash
+curl -X POST http://localhost:8080/api/v1/pools/tank/export \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "force": false
+  }'
+```
+
+## Scrub Best Practices
+
+### When to Scrub
+
+- **Regular Schedule**: Monthly or quarterly
+- **After Disk Failures**: After replacing failed disks
+- **Before Major Operations**: Before pool upgrades or migrations
+- **After Data Corruption**: If data integrity issues are suspected
+
+### Monitoring Scrub Progress
+
+1. **Start Scrub**: Use POST endpoint to start
+2. **Monitor Progress**: Poll GET endpoint every few minutes
+3. **Check Errors**: Monitor `errors` and `repaired` fields
+4. **Wait for Completion**: Wait until `status` is `completed`
+
+### Scrub Performance
+
+- **Impact**: Scrub operations can impact pool performance
+- **Scheduling**: Schedule during low-usage periods
+- **Duration**: Large pools may take hours or days
+- **I/O**: Scrub generates significant I/O load
+
+## Pool Import/Export Use Cases
+
+### Import Use Cases
+
+1. **System Reboot**: Pools are automatically imported on boot
+2. **Manual Import**: Import pools that were exported
+3. **Read-Only Import**: Import pool in read-only mode for inspection
+4. **Recovery**: Import pools from backup systems
+
+### Export Use Cases
+
+1. **System Shutdown**: Export pools before shutdown
+2. **Maintenance**: Export pools for maintenance operations
+3. **Migration**: Export pools before moving to another system
+4. **Backup**: Export pools before creating full backups
+
+## Error Handling
+
+### Pool Not Found
+
+```json
+{
+  "code": "NOT_FOUND",
+  "message": "pool not found"
+}
+```
+
+### Scrub Already Running
+
+```json
+{
+  "code": "CONFLICT",
+  "message": "scrub already in progress"
+}
+```
+
+### Pool in Use (Export)
+
+```json
+{
+  "code": "CONFLICT",
+  "message": "pool is in use, cannot export"
+}
+```
+
+Use `force: true` to force export (use with caution).
