🚀 Quick Start

Installation

npm install @securedrop/core @securedrop/react
# or
yarn add @securedrop/core @securedrop/react

Basic React Integration

import { SecureDropWrapper } from "@securedrop/react";

function App() {
  return (
    <SecureDropWrapper
      maxFiles={10}
      maxFileSize={10 * 1024 * 1024} // 10MB
      securityLevel="moderate"
      allowedTypes={["image/*", "application/pdf", "text/*"]}
      onUploadComplete={(files) => {
        console.log("Successfully uploaded:", files);
      }}
      onThreatDetected={(file, threats) => {
        console.warn("Security threat detected:", threats);
      }}
    />
  );
}

Backend Integration (Express.js)

import { SecureDropAPI, SECURITY_CONFIGS } from "@securedrop/backend";

const secureDropAPI = new SecureDropAPI(
  {
    // Lifecycle hooks
    beforeUpload: async (file, metadata) => {
      console.log(`Uploading ${file.name} from ${metadata.ipAddress}`);
      return true; // Allow upload
    },
    afterScan: async (file, scanResult) => {
      if (!scanResult.isClean) {
        console.warn(`Threats found in ${file.name}:`, scanResult.threats);
      }
    },
  },
  SECURITY_CONFIGS.STRICT
);

app.post("/api/upload", async (req, res) => {
  try {
    const result = await secureDropAPI.uploadFile(req.file, {
      bucketName: "secure-uploads",
      expiryHours: 72,
      requireScan: true,
      generateThumbnails: true,
    });

    res.json({ success: true, file: result });
  } catch (error) {
    res.status(400).json({ error: error.message });
  }
});

🔧 CLI Tools

SecureDrop includes powerful CLI tools for development and testing:

# Generate mock files for testing
npx securedrop-cli generate-mock --type malicious --count 10 --output ./test-files

# Scan existing files for threats
npx securedrop-cli scan ./uploads --level strict --output security-report.json

# Test configuration with sample files
npx securedrop-cli test-config --config ./my-config.json

# Generate framework integration examples
npx securedrop-cli generate-examples --framework react --output ./examples

# Run performance benchmarks
npx securedrop-cli benchmark --files 1000 --size 5 --threads 8

# Initialize configuration templates
npx securedrop-cli init-config --type strict --output production-config.json

📋 Configuration Profiles

Create multiple upload profiles for different use cases:

{
  "profile_name": "strict-documents",
  "description": "High-security document uploads",
  "max_file_size": 5242880,
  "allowed_mime_types": ["application/pdf", "text/*"],
  "blocked_extensions": ["exe", "bat", "cmd", "scr", "vbs", "js"],
  "filename_pattern": "^[a-zA-Z0-9._-]+$",
  "security_level": "strict",
  "virus_scanning_enabled": true,
  "injection_detection_enabled": true,
  "yara_scanning_enabled": true,
  "require_watermark": true,
  "webhook_url": "https://api.yourapp.com/webhooks/securedrop"
}

🔍 Security Features Deep Dive

Advanced Threat Detection

const scanner = new SecurityScanner({
  enableVirusScanning: true,
  enableInjectionDetection: true,
  enableYaraScanning: true,
  customSignatures: [
    {
      name: "Custom Malware Pattern",
      pattern: /malicious_pattern_here/gi,
      severity: "critical",
      description: "Detects custom malware signatures",
    },
  ],
  suspiciousPatterns: [
    /eval\s*\(\s*unescape/gi,
    /<script[^>]*>.*?<\/script>/gi,
  ],
});

const result = await scanner.scanFile(file);
console.log(`File is ${result.isClean ? "clean" : "infected"}`);
console.log(`Confidence: ${result.confidence * 100}%`);
console.log(`Threats:`, result.threats);

File Validation Pipeline

const validator = new FileValidator({
  maxFileSize: 10 * 1024 * 1024,
  allowedMimeTypes: ["image/*", "application/pdf"],
  allowedExtensions: ["jpg", "jpeg", "png", "pdf"],
  maxFiles: 5,
  requireHash: true,
});

const validation = await validator.validateFile(file);
if (!validation.isValid) {
  console.error("Validation failed:", validation.errors);
}

📊 Admin Dashboard

The enhanced admin dashboard provides:

• Multiple Security Profiles: Create and manage different upload configurations
• Real-time Analytics: Monitor upload patterns and security events
• Threat Intelligence: View detected threats and attack patterns
• Audit Logging: Complete compliance trail with export capabilities
• Configuration Testing: Test regex patterns and validation rules
• Webhook Management: Configure real-time notifications

🛠️ Advanced Usage

Custom Storage Backend

import { StorageBackend } from "@securedrop/backend";

class CustomS3Storage implements StorageBackend {
  name = "custom-s3";

  async upload(file: File, path: string): Promise<string> {
    // Your S3 upload logic
    return uploadedPath;
  }

  async download(path: string): Promise<Blob> {
    // Your S3 download logic
    return blob;
  }
}

const api = new SecureDropAPI(hooks, securityConfig);
api.setStorageBackend(new CustomS3Storage());

Lifecycle Hooks

const hooks: LifecycleHooks = {
  beforeUpload: async (file, metadata) => {
    // Custom validation logic
    if (file.size > 50 * 1024 * 1024) return false;
    return true;
  },

  afterValidation: async (file, result) => {
    // Log validation results
    await logValidation(file.name, result);
  },

  afterScan: async (file, scanResult) => {
    // Send threat alerts
    if (!scanResult.isClean) {
      await sendThreatAlert(file, scanResult.threats);
    }
  },

  afterStore: async (uploadResult) => {
    // Post-upload processing
    await processUploadedFile(uploadResult);
  },
};

🧪 Testing & Development

Mock Data Generation

# Generate test files with known threats
securedrop-cli generate-mock --type malicious --count 50

# Generate clean test files
securedrop-cli generate-mock --type image --count 20
securedrop-cli generate-mock --type pdf --count 10

Security Testing

import { TestingUtils } from "@securedrop/testing";

// Test with known attack vectors
const attackVectors = TestingUtils.generateAttackVectors();
for (const vector of attackVectors) {
  const result = await scanner.scanFile(vector.file);
  expect(result.isClean).toBe(false);
  expect(result.threats).toContainEqual(
    expect.objectContaining({ name: vector.expectedThreat })
  );
}
