## 🔐 **Quantum-Safe Cryptography**

ComplyChain now includes **NIST PQC Round 3** quantum-resistant cryptography with **Dilithium3** as the primary algorithm and **RSA-4096** as a fallback.

### **🔄 Fallback Strategy & How to Fix It**

ComplyChain uses a **smart fallback system** to ensure your application always works, even when quantum-safe libraries aren't available:

#### **Automatic Fallback Behavior**
```
Quantum-Safe (Dilithium3) → RSA-4096 → Error Handling
```

**What happens when you see this message:**
```
liboqs-python not available - trying pqcrypto alternatives
Dilithium3 requested but liboqs not available - falling back to RSA-4096 (pqcrypto has known signing issues)
```

**This means:**
- ✅ **Your application continues to work** with RSA-4096 (still very secure)
- ✅ **No data loss or functionality issues**
- ⚠️ **You're not using quantum-safe cryptography** (but still cryptographically secure)

#### **How to Enable True Quantum-Safe Cryptography**

**Option 1: Install liboqs-python (Recommended)**
```bash
# On Ubuntu/Debian
sudo apt-get install liboqs-dev
pip install liboqs-python

# On macOS
brew install liboqs
pip install liboqs-python

# On Windows (using vcpkg)
vcpkg install liboqs
pip install liboqs-python

# Verify installation
python -c "import oqs; print('✓ liboqs available')"
```

**Option 2: Use Docker with Quantum Support**
```bash
# Build quantum-enabled image
docker build -f Dockerfile.oqs -t complychain-quantum .

# Run with quantum-safe enabled
docker run -v /audit_chain:/audit_chain \
  -e QUANTUM_SAFE_ENABLED=true \
  complychain-quantum
```

**Option 3: Manual liboqs Installation**
```bash
# Clone and build liboqs
git clone https://github.com/open-quantum-safe/liboqs.git
cd liboqs
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local ..
make -j$(nproc)
sudo make install

# Install Python bindings
pip install liboqs-python
```

#### **Verification Commands**

**Check if quantum-safe is working:**
```bash
# Test quantum-safe key generation
python -c "
from complychain.crypto_engine import QuantumSafeSigner
signer = QuantumSafeSigner()
signer.generate_keys()
print('✓ Quantum-safe cryptography enabled')
"

# Check available algorithms
python -c "
from complychain.crypto_engine import QuantumSafeSigner
signer = QuantumSafeSigner()
print('Available algorithms:', signer.get_available_algorithms())
"
```

**Expected output with quantum-safe:**
```
✓ Quantum-safe cryptography enabled
Available algorithms: ['dilithium3', 'falcon512', 'sphincs+-sha256-128f-simple']
```

**Expected output with fallback:**
```
liboqs-python not available - falling back to RSA-4096
Available algorithms: ['rsa-4096']
```

### **Quantum-Safe Features**

#### **Dilithium3 Implementation**
- **NIST Standard**: CRYSTALS-Dilithium Level 3 (FIPS 203)
- **Security Level**: 128-bit quantum security
- **Key Sizes**: 1952 bytes (public), 4000 bytes (private)
- **Signature Size**: 3366 bytes
- **Performance**: Optimized for production use

#### **Fallback Mechanism**
- **Automatic fallback** to RSA-4096 if liboqs is unavailable
- **Seamless integration** with existing workflows
- **Warning logs** when quantum backend is unavailable
- **Backward compatibility** with legacy systems

#### **Key Management**
- **PEM format support** for HSM integration
- **Export/import functionality** for key rotation
- **Memory protection** with secure zeroization
- **FIPS 140-3 compliance** for key storage

### **Installation Options**

```bash
# Standard installation (RSA-4096 fallback)
pip install complychain

# With quantum-safe support (Dilithium3 + liboqs)
pip install complychain[quantum]

# With legacy pqcrypto support
pip install complychain[legacy]
```

### **Docker with Quantum Support**

```bash
# Build with quantum-safe support
docker build -f Dockerfile.oqs -t complychain-quantum .

# Run with quantum-safe enabled
docker run -v /audit_chain:/audit_chain \
  -e QUANTUM_SAFE_ENABLED=true \
  complychain-quantum
```

## 🔧 **Troubleshooting**

### **Quantum-Safe Cryptography Issues**

#### **Problem**: "liboqs-python not available - falling back to RSA-4096"
**What it means**: Your system doesn't have quantum-safe cryptography libraries installed.

**Solutions** (in order of preference):
1. **Install liboqs-python** (Recommended):
   ```bash
   # Ubuntu/Debian
   sudo apt-get install liboqs-dev
   pip install liboqs-python
   
   # macOS
   brew install liboqs
   pip install liboqs-python
   
   # Windows
   vcpkg install liboqs
   pip install liboqs-python
   ```

2. **Use Docker with quantum support**:
   ```bash
   docker build -f Dockerfile.oqs -t complychain-quantum .
   docker run -e QUANTUM_SAFE_ENABLED=true complychain-quantum
   ```

3. **Continue with RSA-4096** (still secure):
   - Your application will work fine with RSA-4096
   - No action needed - this is a safe fallback

#### **Problem**: "Dilithium3 key generation fails"
**Solutions**:
1. **Verify liboqs installation**:
   ```bash
   python -c "import oqs; print('✓ liboqs available')"
   ```

2. **Check system dependencies**:
   ```bash
   # Ubuntu/Debian
   sudo apt-get install build-essential cmake
   
   # macOS
   brew install cmake
   ```

3. **Manual installation**:
   ```bash
   git clone https://github.com/open-quantum-safe/liboqs.git
   cd liboqs && mkdir build && cd build
   cmake -DCMAKE_INSTALL_PREFIX=/usr/local ..
   make -j$(nproc) && sudo make install
   pip install liboqs-python
   ```

#### **Problem**: "pqcrypto algorithms (Falcon, SPHINCS+) fail with signing errors"
**Cause**: Known bug in pqcrypto library where key generation works but signing fails.

**Solutions**:
1. **Use liboqs instead** (Recommended):
   ```bash
   pip uninstall pqcrypto
   pip install liboqs-python
   ```

2. **Let ComplyChain handle it** (Automatic):
   - ComplyChain automatically skips pqcrypto and uses RSA-4096
   - No action needed - this is the intended fallback behavior

#### **Problem**: "No private key available - call generate_keys() first"
**Solution**: Generate keys before signing:
```bash
# Using CLI
complychain quantum-keys generate --algorithm dilithium3

# Using Python
from complychain.crypto_engine import QuantumSafeSigner
signer = QuantumSafeSigner()
signer.generate_keys()  # This is required first
signature = signer.sign(data)
```

#### **Problem**: "Signature verification fails"
**Solutions**:
1. **Check algorithm compatibility**:
   ```bash
   # Verify you're using the same algorithm
   python -c "
   from complychain.crypto_engine import QuantumSafeSigner
   signer = QuantumSafeSigner()
   print('Current algorithm:', signer.algorithm)
   "
   ```

2. **Regenerate keys**:
   ```bash
   # Clear old keys and regenerate
   rm -rf ~/.complychain/keys/
   complychain quantum-keys generate
   ```

3. **Check file integrity**:
   ```bash
   # Ensure the file hasn't changed
   sha256sum your_file.txt
   ```

### **Performance Issues**

#### **Problem**: "Scan time exceeds 50ms requirement"
**Solutions**:
1. **Enable test mode** for faster performance:
   ```bash
   export COMPLYCHAIN_TEST_MODE=1
   python -m pytest complychain/tests/ -v
   ```

2. **Check sanctions API connectivity**:
   ```bash
   # Test API connectivity
   curl -I https://api.fincen.gov
   ```

3. **Use cached sanctions data**:
   - ComplyChain automatically caches sanctions data
   - First run may be slower, subsequent runs are faster

### **Installation Issues**

#### **Problem**: "ModuleNotFoundError: No module named 'complychain'"
**Solutions**:
1. **Install in development mode**:
   ```bash
   pip install -e .
   ```

2. **Check Python path**:
   ```bash
   python -c "import sys; print(sys.path)"
   ```

3. **Verify installation**:
   ```bash
   pip list | grep complychain
   ```

#### **Problem**: "PyPDF2 deprecation warnings"
**Solution**: This is just a warning, not an error. PyPDF2 still works:
```bash
# Ignore the warning (safe to do)
export PYTHONWARNINGS="ignore::DeprecationWarning"
```

### **Configuration Issues**

#### **Problem**: "Configuration file not found"
**Solutions**:
1. **Create default config**:
   ```bash
   cp config.yaml.example config.yaml
   ```

2. **Use environment variables**:
   ```bash
   export COMPLYCHAIN_LOG_LEVEL=DEBUG
   export COMPLYCHAIN_QUANTUM_SAFE_ENABLED=true
   ```

3. **Specify config file**:
   ```bash
   complychain --config /path/to/config.yaml
   ```

### **Docker Issues**

#### **Problem**: "Docker build fails"
**Solutions**:
1. **Use the correct Dockerfile**:
   ```bash
   # For quantum support
   docker build -f Dockerfile.oqs .
   
   # For standard build
   docker build -f Dockerfile .
   ```

2. **Check Docker resources**:
   ```bash
   # Ensure enough memory/CPU
   docker system info
   ```

3. **Clean Docker cache**:
   ```bash
   docker system prune -a
   ```
