🔐 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)

# 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

# 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

# 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:

# 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']

🔧 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):

   # 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:

   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:

   python -c "import oqs; print('✓ liboqs available')"
   

2. Check system dependencies:

   # Ubuntu/Debian
   sudo apt-get install build-essential cmake
   
   # macOS
   brew install cmake
   

3. Manual installation:

   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):

   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:

# 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:

   # 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:

   # Clear old keys and regenerate
   rm -rf ~/.complychain/keys/
   complychain quantum-keys generate
   

3. Check file integrity:

   # 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:

   export COMPLYCHAIN_TEST_MODE=1
   python -m pytest complychain/tests/ -v
   

2. Check sanctions API connectivity:

   # 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:

   pip install -e .
   

2. Check Python path:

   python -c "import sys; print(sys.path)"
   

3. Verify installation:

   pip list | grep complychain
   

Problem: "PyPDF2 deprecation warnings"

Solution: This is just a warning, not an error. PyPDF2 still works:

# Ignore the warning (safe to do)
export PYTHONWARNINGS="ignore::DeprecationWarning"

Configuration Issues

Problem: "Configuration file not found"

Solutions:

1. Create default config:

   cp config.yaml.example config.yaml
   

2. Use environment variables:

   export COMPLYCHAIN_LOG_LEVEL=DEBUG
   export COMPLYCHAIN_QUANTUM_SAFE_ENABLED=true
   

3. Specify config file:

   complychain --config /path/to/config.yaml
   

Docker Issues

Problem: "Docker build fails"

Solutions:

1. Use the correct Dockerfile:

   # For quantum support
   docker build -f Dockerfile.oqs .
   
   # For standard build
   docker build -f Dockerfile .
   

2. Check Docker resources:

   # Ensure enough memory/CPU
   docker system info
   

3. Clean Docker cache:

   docker system prune -a
