What is post-quantum cryptography?

Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to be secure against attacks from quantum computers. Unlike current encryption methods that could be broken by quantum computing, PQC uses mathematical problems that remain difficult even for quantum computers. PQ Crypta implements NIST-standardized algorithms including ML-KEM-1024 for key encapsulation and ML-DSA-87 for digital signatures.

Why do I need post-quantum encryption now?

The threat is immediate due to 'harvest now, decrypt later' attacks where adversaries collect encrypted data today to decrypt once quantum computers become available. Organizations must protect sensitive data with quantum-resistant encryption now to prevent future breaches. NIST has already standardized PQC algorithms, making migration essential for long-term security.

What algorithms does PQ Crypta support?

PQ Crypta supports 28 cryptographic algorithms including NIST-standardized ML-KEM-1024, ML-DSA-87, and SLH-DSA, plus hybrid modes combining classical and post-quantum security. Our platform offers classical (X25519 + Ed25519), pure post-quantum, hybrid transitions, and experimental approaches like FN-DSA and lattice fusion algorithms.

Is PQ Crypta free to use?

Yes, PQ Crypta offers free access to post-quantum encryption tools including our interactive encryption platform, compression tools, regex generator, and API access. We provide open-source implementations and developer-friendly APIs for integration into your applications at no cost.

How secure is ML-KEM-1024?

ML-KEM-1024 (formerly CRYSTALS-Kyber) is a NIST-standardized algorithm providing security level 5, equivalent to AES-256 against quantum attacks. It uses lattice-based cryptography proven resistant to both classical and quantum computing attacks, making it suitable for top-secret classified information protection.

Can I integrate PQ Crypta into my application?

Yes, PQ Crypta provides REST APIs at https://api.pqcrypta.com with comprehensive endpoints for encryption, decryption, key generation, and cryptographic operations. We support 22 programming languages with code examples and offer developer documentation for seamless integration.

What is hybrid cryptography?

Hybrid cryptography combines classical cryptographic algorithms (like X25519 and Ed25519) with post-quantum algorithms (like ML-KEM-1024) to provide defense-in-depth security. This approach ensures your data remains secure even if one algorithm family is compromised, following NIST recommendations for transition strategies.

How does PQ Crypta compare to standard encryption?

Traditional encryption (RSA, ECDH, ECDSA) will be broken by quantum computers using Shor's algorithm. PQ Crypta uses lattice-based and hash-based algorithms that resist quantum attacks while maintaining performance comparable to classical encryption. Our platform offers transparent upgrade paths from vulnerable to quantum-safe cryptography.
