#### **Backward Compatibility**

// Getters and setters for existing code compatibility
|
||||
get encryptionKey() {
|
||||
return this._getSecureKey('encryptionKey');
|
||||
}
|

|

set encryptionKey(value) {

||||

|
||||
}
|
||||
```
|
||||
|
||||
#### **Security Benefits**
|
||||
- **Memory Protection:** Keys inaccessible via direct property access
|
||||
- **Debugger Resistance:** Keys not visible in browser developer tools
|
||||
- **Access Control:** All key access goes through validation
|
||||
- **Automatic Cleanup:** Keys automatically removed from memory
|
||||
- **Threat Response:** Immediate key destruction capabilities

});
|
||||
|
||||
// Production output: No debug logs
|
||||
// Development output: [SecureBit:DEBUG] Connection established { userId: 'user123', encryptionKey: '[REDACTED]', messageContent: 'Hello, world!', sessionId: '[REDACTED]' }
|
||||
```
|
||||
|
||||
#### **Security Benefits**
|
||||
- **Data Protection:** Encryption keys, message content, and tokens are automatically sanitized
|
||||
- **Privacy Preservation:** User privacy maintained in production logs
|
||||
- **Debugging Support:** Safe debugging information without sensitive content
|
||||
- **Rate Limiting:** Prevents log spam and memory exhaustion
|
||||
- **Compliance:** Meets privacy regulations and security standards

// Security verification

await this._verifySecurityParameters();

```
|
||||
|
||||
#### **Security Benefits**
|
||||
- **Race Condition Prevention:** Eliminates timing-based attacks during key generation
|
||||
- **Connection Integrity:** Ensures atomic connection establishment
|
||||
- **Error Recovery:** Automatic rollback for failed operations
|
||||
- **Deadlock Prevention:** Timeout-based emergency recovery
|
||||
- **Diagnostic Capability:** Comprehensive phase tracking for error identification

## 🔒 Layer 13: Mutex Framework (Race Condition Protection)
|
||||
|
||||
### Purpose
|
||||
Prevents race conditions during connection establishment and cryptographic operations through advanced mutex coordination system.
|
||||
|
||||
### Technical Implementation
|
||||
- **Custom Mutex System:** `_withMutex('connectionOperation')` with 15-second timeout
|
||||
- **Atomic Operations:** Serialized connection operations to prevent conflicts
|
||||
- **Deadlock Prevention:** Emergency recovery mechanisms with automatic cleanup
|
||||
- **Operation Tracking:** Unique `operationId` for comprehensive diagnostics
|
||||
|
||||
### Security Benefits
|
||||
- **Race Condition Prevention:** Eliminates timing-based attacks during key generation
|
||||
- **Connection Integrity:** Ensures atomic connection establishment
|
||||
- **Error Recovery:** Automatic rollback via `_cleanupFailedOfferCreation()` on failures
|
||||
- **Diagnostic Capability:** Phase tracking for precise error identification
|
||||
|
||||
### Implementation Details
|
||||
```javascript
|
||||
// Mutex-protected connection operations
|
||||
await this._withMutex('connectionOperation', async () => {
|
||||
const operationId = this._generateOperationId();
|
||||
try {
|
||||
await this._generateEncryptionKeys();
|
||||
await this._validateConnectionParameters();
|
||||
await this._establishSecureChannel();
|
||||
} catch (error) {
|
||||
await this._cleanupFailedOfferCreation(operationId);
|
||||
throw error;
|
||||
}
|
||||
});
|
||||
```

## 🔐 Layer 14: Secure Key Storage (WeakMap Isolation)
|
||||
|
||||
### Purpose
|
||||
Replaces public key properties with private WeakMap-based storage to prevent unauthorized access and memory exposure.
|
||||
|
||||
### Technical Implementation
|
||||
- **WeakMap Storage:** `_secureKeyStorage` for all cryptographic keys
|
||||
- **Private Access Methods:** `_getSecureKey()`, `_setSecureKey()`, `_initializeSecureKeyStorage()`
|
||||
- **Key Validation:** `_validateKeyValue()` with type and format checking
|
||||
- **Key Rotation:** `_rotateKeys()` with secure key replacement
|
||||
- **Emergency Wipe:** `_emergencyKeyWipe()` for threat response
|
||||
|
||||
### Security Benefits
|
||||
- **Memory Protection:** Keys inaccessible via direct property access or debugger
|
||||
- **Access Control:** Secure getters/setters with validation
|
||||
- **Key Lifetime Management:** Automatic rotation and expiration
|
||||
- **Threat Response:** Immediate key destruction capabilities
|
||||
|
||||
### Implementation Details
|
||||
```javascript
|
||||
// Secure key storage initialization
|
||||
this._initializeSecureKeyStorage();
|
||||
|
||||
// Secure key access
|
||||
const encryptionKey = this._getSecureKey('encryptionKey');
|
||||
this._setSecureKey('encryptionKey', newKey, { validate: true });
|
||||
|
||||
// Emergency key wipe
|
||||
this._emergencyKeyWipe();
|
||||
```

## 🛡️ Layer 15: Production Security Logging (Data Sanitization)
|
||||
|
||||
### Purpose
|
||||
Implements environment-aware logging system that prevents sensitive data exposure while maintaining useful diagnostics.
|
||||
|
||||
### Technical Implementation
|
||||
- **Environment Detection:** Automatic production vs development mode detection
|
||||
- **Data Sanitization:** `_secureLog()` replacing `console.log` with sanitization
|
||||
- **Log Level Control:** Production (warn+error only), Development (debug+)
|
||||
- **Rate Limiting:** Automatic log spam prevention and cleanup
|
||||
- **Memory Management:** Automatic cleanup for log counters
|
||||
|
||||
### Security Benefits
|
||||
- **Data Protection:** Encryption keys, message content, and tokens are sanitized
|
||||
- **Privacy Preservation:** User privacy maintained in production logs
|
||||
- **Debugging Support:** Safe debugging information without sensitive content
|
||||
- **Compliance:** Meets privacy regulations and security standards
|
||||
|
||||
### Implementation Details
|
||||
```javascript
|
||||
// Secure logging with data sanitization
|
||||
this._secureLog('debug', 'Connection established', {
|
||||
userId: '[REDACTED]',
|
||||
encryptionKey: '[REDACTED]',
|
||||
messageContent: '[REDACTED]'
|
||||
});
|
||||
|
||||
// Environment-aware logging
|
||||
if (this._isProductionMode()) {
|
||||
// Only critical errors and warnings
|
||||
} else {
|
||||
// Full debugging information (sanitized)
|
||||
}
|
||||
```
