Installation

npm install @averox/cryptosphare
# or
yarn add @averox/cryptosphare

Quick Start

import { Config } from '@averox/cryptosphare';

// Initialize the SDK
const sdk = new Config({
  encryption: {
    forwardSecrecy: true,
    algorithm: 'AES-256-GCM',
  },
});

// Initialize secure features
sdk.initialize();

Configuration Options

Basic Configuration

const sdk = new Config({
  // Encryption settings
  encryption: {
    forwardSecrecy: true, // Enable perfect forward secrecy
    quantumResistant: false, // Enable quantum-resistant algorithms
    algorithm: 'AES-256-GCM', // 'AES-256-GCM' or 'ChaCha20-Poly1305'
    keyRotationInterval: 24, // Key rotation interval in hours
  },

  // Media streaming settings
  streaming: {
    audio: true, // Enable audio streaming
    video: true, // Enable video streaming
    videoQuality: '720p', // '480p', '720p', or '1080p'
    audioQuality: 'high', // 'low', 'medium', or 'high'
  },

  // Monitoring settings
  monitoring: {
    encryptionLogs: true, // Enable encryption operation logs
    keyMonitoring: true, // Enable key management monitoring
    performanceMetrics: true, // Enable performance metrics
  },
});

Event Monitoring

Monitor encryption operations and key management events:

// Listen for encryption events
sdk.on('encryptionOperation', (stats) => {
  console.log('Encryption operation:', stats);
  // stats: {
  //   operationId: string;
  //   type: 'encrypt' | 'decrypt';
  //   success: boolean;
  //   latency: number;
  //   timestamp: Date;
  // }
});

// Listen for key rotation events
sdk.on('keyRotated', (event) => {
  console.log('Key rotation:', event);
  // event: {
  //   type: 'rotated';
  //   status: 'active';
  //   timestamp: Date;
  //   metadata: { oldKey: string; newKey: string; }
  // }
});

// Listen for metrics updates
sdk.on('metricsUpdate', (metrics) => {
  console.log('Metrics update:', metrics);
  // metrics: {
  //   totalOperations: number;
  //   successRate: number;
  //   averageLatency: number;
  //   lastUpdated: Date;
  // }
});

Custom Event Handlers

Define custom handlers for specific events:

const sdk = new Config({
  monitoring: {
    eventHandlers: {
      // Handle key rotation events
      onKeyRotation: (event) => {
        updateKeyRotationUI(event);
      },

      // Handle encryption operations
      onEncryption: (stats) => {
        updateEncryptionStatsUI(stats);
      },

      // Handle metrics updates
      onMetricsUpdate: (metrics) => {
        updateDashboardUI(metrics);
      },
    },
  },
});

UI Integration Examples

Real-time Encryption Monitoring

// React component example
function EncryptionMonitor() {
  const [stats, setStats] = useState([]);

  useEffect(() => {
    const sdk = new Config({
      monitoring: {
        encryptionLogs: true,
        eventHandlers: {
          onEncryption: (newStats) => {
            setStats(prev => [...prev, newStats]);
          }
        }
      }
    });

    sdk.initialize();
  }, []);

  return (
    <div>
      <h2>Encryption Operations</h2>
      {stats.map(stat => (
        <div key={stat.operationId}>
          <p>Type: {stat.type}</p>
          <p>Success: {stat.success ? '✅' : '❌'}</p>
          <p>Latency: {stat.latency}ms</p>
        </div>
      ))}
    </div>
  );
}

Security Dashboard

// React component example
function SecurityDashboard() {
  const [metrics, setMetrics] = useState(null);

  useEffect(() => {
    const sdk = new Config({
      monitoring: {
        performanceMetrics: true,
        eventHandlers: {
          onMetricsUpdate: (newMetrics) => {
            setMetrics(newMetrics);
          }
        }
      }
    });

    sdk.initialize();
  }, []);

  return (
    <div>
      <h2>Security Metrics</h2>
      {metrics && (
        <>
          <p>Total Operations: {metrics.totalOperations}</p>
          <p>Success Rate: {(metrics.successRate * 100).toFixed(2)}%</p>
          <p>Average Latency: {metrics.averageLatency.toFixed(2)}ms</p>
          <p>Last Updated: {metrics.lastUpdated.toLocaleString()}</p>
        </>
      )}
    </div>
  );
}

Best Practices
