PostQuantum DualUSB Token Library v0.1.0

PostQuantum DualUSB Token Library v0.1.0

We're excited to announce the first official release of PostQuantum DualUSB Token Library - a Python package that brings enterprise-grade security to dual USB backup systems with future-proof cryptography.

What makes this special?

In an era where quantum computers threaten traditional encryption, this library provides a practical solution for securing sensitive data across two USB devices. Whether you're protecting cryptocurrency keys, enterprise secrets, or personal data, this release gives you military-grade security that's ready for the quantum age.

Key capabilities in this release

Quantum-resistant protection

• Post-quantum digital signatures using the Dilithium algorithm
• AES-256-GCM encryption with authenticated data
• Memory-hard key derivation using Argon2id
• Cryptographic audit trails with HMAC-SHA256

Dual USB security model

• Secrets split across two physical devices for redundancy
• No single point of failure - losing one USB doesn't compromise security
• Hardware binding prevents device cloning attacks
• Tamper-evident logging tracks all operations

Production-ready features

• Secure memory management with automatic cleanup
• Protection against timing-based attacks
• Works reliably on Windows, Linux, and macOS
• Real-time progress monitoring for long operations

Getting started

Installing and using the library is straightforward:

# Install from PyPI
pip install pqcdualusb

# Set up your dual USB configuration
pqcdualusb init --primary /media/usb1 --secondary /media/usb2

# Create an encrypted backup
pqcdualusb backup --data "sensitive.json" --passphrase "your-secure-passphrase"

Who should use this?

This library is designed for anyone who needs serious security:

• Developers building offline password managers or key storage systems
• Organizations requiring air-gapped security for sensitive operations
• Cryptocurrency users who want hardware-level protection for wallet keys
• Security professionals implementing enterprise key custody solutions
• Privacy-conscious individuals who want quantum-proof personal data protection

Performance you can count on

We've optimized the library for real-world usage:

• USB device detection completes in under 1 second
• Token creation takes less than 5 seconds
• Backup and restore operations finish in 1-10 seconds
• Memory usage stays under 100MB even for large operations

What's coming next

This initial release establishes the foundation. Future versions will include:

• Enhanced documentation with step-by-step tutorials
• Additional post-quantum cryptographic algorithms
• Performance optimizations for large-scale deployments
• Extended platform support and testing
