# ✅ S3 File Access - 180 Days Updated!

## 🎯 Updated Configuration

**Haan bilkul! Ab aap 180 days ki files ko access kar sakte hain!**

### 📅 Updated Settings:

```javascript
// Default user permissions ab 180 days
const defaultPermissions = {
  read: true,
  write: false,
  delete: false,
  dateRestriction: true,
  dayLimit: 180, // ✅ 180 days access (matches S3 retention)
  serviceRestriction: false,
  allowedServices: [],
};
```

### ⚙️ Production Configuration:

```javascript
// S3 Security Configuration
s3Security: {
  enabled: true,
  defaultExpiration: 3600, // 1 hour for pre-signed URLs
  maxFileAge: 180, // ✅ Users can access files max 180 days old
  accessControl: true,
},
```

## 🔄 Perfect Alignment with Retention Policy

### Database vs S3 vs Access Policy:

| Component            | Retention Period | Purpose                        |
| -------------------- | ---------------- | ------------------------------ |
| **MongoDB Database** | 14 days          | Active/recent logs for queries |
| **S3 Storage**       | 180 days         | Long-term file storage         |
| **User Access**      | 180 days         | ✅ Can access all S3 files     |

### 💡 Logic:

- **0-14 days**: Files available in both DB + S3
- **15-180 days**: Files only in S3 (DB cleaned up)
- **180+ days**: Files deleted from S3 (no access)

## 🛡️ Security Flow Remains Same

### Access Steps:

1. **User Authentication** - Bearer token required
2. **Generate Access Token** - Request file access permission
3. **File Permission Check** - ✅ Now checks for 180 days instead of 30
4. **Pre-signed URL** - Generate secure download link
5. **Download File** - Access file securely

### Example Access Timeline:

```javascript
// File uploaded on: Jan 1, 2025
// Current date: June 1, 2025 (150 days later)

// Before Update: ❌ Access denied (30 days limit)
// After Update:  ✅ Access granted (180 days limit)
```

## 🧪 Test Updated Settings

### Quick Test:

```bash
node -e "
const { S3SecurityManager } = require('./lib/s3Security');
const manager = new S3SecurityManager({
  accessKeyId: 'test',
  secretAccessKey: 'test',
  region: 'us-east-1',
  bucket: 'test'
});
manager.getUserPermissions('user123').then(perms =>
  console.log('📅 User can access files up to', perms.dayLimit, 'days old')
);"
```

**Output**: `📅 User can access files up to 180 days old`
