```

**System Requirements:**
- Node.js 16.0.0 or higher
- TypeScript 4.5+ (for TypeScript projects)
- Modern ES2020+ environment

## 🚀 Quick Start

### Option 1: Using CLI Configuration (Recommended)

If you've authenticated with the KeyVault CLI, the SDK automatically uses your configuration:

```typescript
import { KeyVaultSDK, createKeyVaultFromConfig } from 'keyvault-api-sdk';

// Method 1: Auto-load configuration
const sdk = await createKeyVaultFromConfig();

// Method 2: Manual configuration loading
const sdk = new KeyVaultSDK();
await sdk.configfile(); // Loads from ~/.keyvault/config.json

// Now you can use the SDK with your authenticated context
const stripeKey = await sdk.service('stripe').key('production');
```

### Option 2: Direct API Token (Legacy/CI)

```typescript
import { KeyVaultSDK } from 'keyvault-api-sdk';

const sdk = new KeyVaultSDK({
  apiUrl: 'https://1pass.vercel.app',
  apiToken: 'your-jwt-token-here'
});
```

### Option 3: Environment Variables

```typescript
import { createKeyVaultFromEnv } from 'keyvault-api-sdk';

// Set environment variables:
// KEYVAULT_API_URL=https://1pass.vercel.app
// KEYVAULT_API_TOKEN=your-jwt-token

const sdk = createKeyVaultFromEnv();
```

## 🔑 Core API Key Operations

### Basic Key Management

```typescript
// Get key by unique ID
const key = await sdk.getKey('key-id-123');

// Get key by service name (most common pattern)
const openaiKey = await sdk.getKeyByService('openai');
const stripeKey = await sdk.getKeyByService('stripe', 'production');

// Create new key with automatic encryption
await sdk.createKey({
  name: 'OpenAI Production Key',
  service: 'openai',
  value: 'sk-1234567890abcdef...',
  metadata: { 
    environment: 'production',
    department: 'ai-research',
    owner: 'john.doe@company.com'
  }
});

// Update existing key
await sdk.updateKey('key-id-123', {
  name: 'Updated Key Name',
  metadata: { lastRotated: new Date().toISOString() }
});

// Delete key
await sdk.deleteKey('key-id-123');

// List all accessible keys
const keys = await sdk.listKeys();
```

### Fluent Interface API

```typescript
// Service-based key access (recommended)
const stripeKey = await sdk.service('stripe').key('production');
const githubToken = await sdk.service('github').key('personal-access');
const databaseUrl = await sdk.service('database').key('connection-string');

// Multiple services in sequence
const openaiKey = await sdk.service('openai').key('gpt-4');
const anthropicKey = await sdk.service('anthropic').key('claude');
```

## 👥 Team Collaboration

### Team Context Management

```typescript
// Switch to team context for all subsequent operations
const productionTeam = sdk.team('production-environment');
const stripeKey = await productionTeam.service('stripe').key('live');
const databaseUrl = await productionTeam.service('database').key('primary');

// One-off team operations
const stagingKey = await sdk.team('staging').service('api').key('test-token');
const devEndpoint = await sdk.team('development').endpoint('backend-api');

// Chain team operations
const prodStripe = await sdk.team('production').service('stripe').key('live');
const prodDatabase = await sdk.team('production').service('database').key('primary');
```

### Multi-Environment Workflows

```typescript
// Environment-specific key management
const environments = ['development', 'staging', 'production'];

for (const env of environments) {
  const dbUrl = await sdk.team(env).service('database').key('connection');
  const apiKey = await sdk.team(env).service('external-api').key('token');
  
  console.log(`${env.toUpperCase()}: DB=${dbUrl}, API=${apiKey}`);
}

// Team-specific endpoint management
const cdnUrl = await sdk.team('frontend').endpoint('cdn-primary');
const apiGateway = await sdk.team('backend').endpoint('api-gateway');
```

## 🌐 Endpoint Management

```typescript
// Get endpoint URLs for different environments
const productionApi = await sdk.endpoint('production-api');
const stagingDatabase = await sdk.endpoint('staging-database');

// Team-specific endpoints
const frontendCdn = await sdk.team('frontend-team').endpoint('cdn-url');
const backendApi = await sdk.team('backend-team').endpoint('api-server');

// Multiple endpoints
const endpoints = {
  api: await sdk.team('production').endpoint('api-gateway'),
  cdn: await sdk.team('production').endpoint('cdn-primary'),
  database: await sdk.team('production').endpoint('database-cluster')
};
```

# Initialize KeyVault configuration from environment
if [ ! -z "$KEYVAULT_CONFIG" ]; then
  echo "$KEYVAULT_CONFIG" > ~/.keyvault/config.json
fi

# Start application
exec "$@"
```

## 🛡️ Security Architecture

### Zero-Trust Encryption Model

KeyVault SDK implements a zero-trust security architecture where API keys are encrypted client-side before transmission:

```typescript
// When you call configfile(), the SDK:
await sdk.configfile();

// 1. Loads your encryption keys from ~/.keyvault/config.json
// 2. Uses these keys to encrypt/decrypt your API keys
// 3. All API key operations use client-side encryption

// Creating keys - API keys are encrypted before sending to server
await sdk.createKey({
  name: 'Stripe Production',
  service: 'stripe',
  value: 'sk_live_very_sensitive_key_here' // ← Encrypted client-side
});

// Retrieving keys - encrypted data received from server, decrypted locally
const key = await sdk.service('stripe').key('production'); // ← Decrypted API key
```

### Encryption Details

- **Algorithm**: AES-256-GCM with authenticated encryption
- **Key Storage**: Local encryption keys stored in `~/.keyvault/config.json`
- **Encryption Keys**: User-specific and team-specific encryption keys
- **Team Isolation**: Separate encryption keys for team-shared API keys
- **Transport**: TLS 1.3 for all network communications

### Security Best Practices

```typescript
// 1. Always use config file method for production
const sdk = await createKeyVaultFromConfig(); // ✅ Secure

// 2. Avoid hardcoding tokens in source code
const sdk = new KeyVaultSDK({ 
  apiToken: 'hardcoded-token' // ❌ Not recommended
});

// 3. Use team contexts for separation
const prodVault = sdk.team('production');   // ✅ Isolated
const devVault = sdk.team('development');   // ✅ Isolated

// 4. Handle errors gracefully
try {
  const key = await sdk.service('stripe').key('production');
} catch (error) {
  // Don't log sensitive data
  console.error('Failed to retrieve key:', error.message);
}

// 5. Regular key rotation
await sdk.updateKey(keyId, {
  value: newKeyValue,
  metadata: { 
    rotatedAt: new Date().toISOString(),
    rotatedBy: process.env.USER 
  }
});
```

### Threat Model Protection

| Threat | Protection | Implementation |
|--------|------------|----------------|
| **Man-in-the-Middle** | TLS 1.3 + Certificate Pinning | Automatic |
| **Server Compromise** | Client-side encryption | User private keys |
| **Credential Theft** | Encrypted storage | AES-256-GCM |
| **Team Data Leakage** | Team isolation | Separate encryption keys |
| **Privilege Escalation** | Role-based access | Server-side RBAC |
| **Audit Trail** | Comprehensive logging | Metadata tracking |

## 🔧 Advanced Configuration

### Environment Variables

```bash
# API Configuration
export KEYVAULT_API_URL="https://your-instance.com/api"
export KEYVAULT_API_TOKEN="your-jwt-token"

# Custom Configuration Directory
export KEYVAULT_CONFIG_DIR="/custom/config/path"

# Debug Mode
export KEYVAULT_DEBUG="true"

# Team Context
export KEYVAULT_DEFAULT_TEAM="production-team"

# Security Options
export KEYVAULT_ENCRYPTION_LEVEL="high" # high, medium, low
export KEYVAULT_CACHE_TTL="300" # seconds
```

### Configuration File Structure

```json
{
  "apiUrl": "https://1pass.vercel.app",
  "token": "jwt-authentication-token",
  "email": "user@company.com",
  "activeTeamId": "current-team-uuid",
  "personalKeys": {
    "address": "0x...",
    "publicKey": "user-encryption-public-key",
    "privateKey": "user-encryption-private-key",
    "createdAt": "2025-01-15T10:30:00Z"
  },
  "teamKeys": {
    "team-name": {
      "address": "0x...",
      "publicKey": "team-encryption-public-key",
      "privateKey": "team-encryption-private-key", 
      "createdAt": "2025-01-15T10:30:00Z"
    }
  }
}
```

**Important**: This configuration file contains **encryption keys** and authentication tokens, not your actual API keys. Your API keys (Stripe, OpenAI, etc.) are stored encrypted on KeyVault servers and are decrypted locally using these encryption keys.

### Custom Initialization

```typescript
import { KeyVaultSDK, KeyVaultConfig } from 'keyvault-api-sdk';

const config: KeyVaultConfig = {
  apiUrl: 'https://your-instance.com/api',
  apiToken: process.env.KEYVAULT_TOKEN,
  encryptionLevel: 'high',
  cacheOptions: {
    ttl: 300,
    maxSize: 1000
  },
  retryOptions: {
    maxRetries: 3,
    retryDelay: 1000
  },
  timeout: 30000
};

const sdk = new KeyVaultSDK(config);
```

## 📊 Performance & Optimization

### Caching Strategy

```typescript
// SDK automatically caches keys for performance
const key1 = await sdk.service('stripe').key('live'); // API call
const key2 = await sdk.service('stripe').key('live'); // Cache hit

// Manual cache control
sdk.clearCache(); // Clear all cached keys
sdk.invalidateKey('service-name', 'key-name'); // Clear specific key

// Configure cache behavior
const sdk = new KeyVaultSDK({
  cacheOptions: {
    ttl: 600,        // 10 minutes
    maxSize: 500,    // Max 500 cached keys
    enabled: true    // Enable/disable caching
  }
});
```

### Cache Operations

```typescript
// Clear all cached keys
sdk.clearCache();

// Check cache size
const cacheSize = sdk.getCacheSize();
console.log(`Currently caching ${cacheSize} keys`);

// Control caching behavior
const key1 = await sdk.getKey('key-id', true);  // Use cache
const key2 = await sdk.getKey('key-id', false); // Skip cache
```

### Performance Monitoring

```typescript
// Basic cache monitoring
const cacheSize = sdk.getCacheSize();
console.log(`Cache currently holds ${cacheSize} keys`);

// Manual cache management for performance
sdk.clearCache(); // Clear when memory is concern

// Use cache control for performance optimization
const frequentKey = await sdk.getKeyByService('stripe', 'live', true); // Use cache
const oneTimeKey = await sdk.getKeyByService('temp-service', 'key', false); // Skip cache
```

## 🧪 Testing Support

### Basic Testing

```typescript
import { createKeyVaultFromEnv } from 'keyvault-api-sdk';

// Create SDK instance for testing
const sdk = createKeyVaultFromEnv();

// Test with environment variables
// Set KEYVAULT_API_URL and KEYVAULT_API_TOKEN in your test environment

test('key retrieval', async () => {
  const key = await sdk.getKeyByService('test-service', 'test-key');
  expect(key).toBeTruthy();
});

test('team operations', async () => {
  const teamKey = await sdk.team('test-team').service('stripe').key('test');
  expect(teamKey).toMatch(/^sk_test_/);
});
```

## 🔄 Migration Guide

### From v1.0.x to v1.1.0

```typescript
// OLD (v1.0.x) - Still works but deprecated
const sdk = new KeyVaultSDK({ apiToken: 'token' });
const key = await sdk.getKeyByService('stripe');

// NEW (v1.1.0) - Recommended approach
const sdk = await createKeyVaultFromConfig();
const key = await sdk.service('stripe').key('production');

// Migration steps:
// 1. Install KeyVault CLI: npm install -g keyvault-cli
// 2. Authenticate: keyvault login
// 3. Update SDK usage to use config file method
// 4. Switch to fluent interface for better DX
```

### Breaking Changes (None)

v1.1.0 is fully backward compatible with v1.0.x. All existing code will continue to work without modifications.

## 🆘 Troubleshooting

### Common Issues

#### Authentication Problems

```typescript
// Error: "Invalid API token"
try {
  const sdk = await createKeyVaultFromConfig();
} catch (error) {
  if (error.message.includes('Invalid API token')) {
    console.log('Solution: Run "keyvault login" to re-authenticate');
  }
}
```

#### Configuration Issues

```typescript
// Error: "Config file not found"
import { existsSync } from 'fs';
import { homedir } from 'os';
import { join } from 'path';

const configPath = join(homedir(), '.keyvault', 'config.json');
if (!existsSync(configPath)) {
  console.log('Solution: Run "keyvault login" to create config file');
}
```

#### Team Access Problems

```typescript
// Error: "Team not found" or "Access denied"
try {
  const key = await sdk.team('nonexistent-team').service('stripe').key('live');
} catch (error) {
  if (error.status === 404) {
    console.log('Solution: Check team name or request access');
  }
}
```

#### Performance Issues

```typescript
// Slow key retrieval
const sdk = new KeyVaultSDK({
  cacheOptions: {
    ttl: 600,        // Increase cache TTL
    maxSize: 1000,   // Increase cache size
    enabled: true    // Enable caching
  }
});

// Use batch operations for multiple keys
const keys = await sdk.batchGetKeys([
  { service: 'stripe', key: 'live' },
  { service: 'openai', key: 'production' }
]);
```

### Debug Mode

```typescript
// Enable debug logging
process.env.KEYVAULT_DEBUG = 'true';

const sdk = await createKeyVaultFromConfig();
// Detailed logging will be output to console

// Or programmatically
const sdk = new KeyVaultSDK({ debug: true });
```

### Error Handling Best Practices

```typescript
try {
  const key = await sdk.service('stripe').key('production');
} catch (error) {
  if (error.message.includes('API token not available')) {
    // Handle authentication errors
    console.error('Authentication failed:', error.message);
    console.log('Run configfile() or provide API token');
  } else if (error.message.includes('Failed to decrypt')) {
    // Handle decryption errors
    console.error('Decryption failed:', error.message);
    console.log('Key may have been encrypted with different private key');
  } else if (error.message.includes('Config not loaded')) {
    // Handle configuration errors
    console.error('Configuration error:', error.message);
    console.log('Call configfile() first');
  } else {
    // Handle unexpected errors
    console.error('Unexpected error:', error.message);
  }
}
```
