6.1 Production Readiness

Status: APPROVED FOR PRODUCTION

Justification: - All critical tests passed (100% success rate) - No security vulnerabilities identified - Performance meets or exceeds expectations - VeraCrypt integration seamless - User interface intuitive

6.2 User Guidance

Recommended Default Settings: - SSD/NVMe drives: Use "SSD (Encrypt + TRIM)" algorithm - Hard drives: Use "NIST" or "DoD 3-pass" algorithm - Maximum security: Use "Gutmann" (accept slower performance) - Quick cleanup: Use "Zero" or "Random" (1-pass)

Best Practices: 1. Verify TRIM is enabled on SSDs (Windows: fsutil behavior query DisableDeleteNotify) 2. Close other applications during large file operations 3. Ensure adequate free space for Secure Copy operations 4. Use administrator privileges for optimal TRIM support
