Quantum Encryption Software

Quantum encryption software uses cryptographic algorithms designed to resist attacks from quantum computers. Traditional encryption like RSA and ECC relies on mathematical problems that quantum computers can solve efficiently using Shor's algorithm. Post-quantum cryptography uses different mathematical structures (lattices, codes, hash functions) that remain hard even for quantum computers.

QNSQY implements NIST FIPS 203 (ML-KEM) for quantum-safe key encapsulation, FIPS 204 (ML-DSA) for lattice-based digital signatures, FIPS 205 (SLH-DSA) for stateless hash-based signatures, FIPS 206 (draft) (FN-DSA/Falcon) for compact NTRU-based signatures, HQC for code-based key encapsulation, and LMS (SP 800-208) for stateful hash-based signatures. By default, post-quantum algorithms are hybridized with their classical counterpart (X25519 for KEMs, Ed25519 for signatures) for defense-in-depth. Business-tier users can optionally disable the classical half for compliance profiles that require pure PQC.

Harvest Now, Decrypt Later (HNDL) is an active threat. Nation-state actors are collecting encrypted data today, storing it until quantum computers can break the encryption. Medical records, legal documents, financial data, and trade secrets encrypted with RSA or ECDH today will become readable once a cryptographically-relevant quantum computer is operational. Data that requires confidentiality for decades needs quantum-safe protection now.

Download QNSQY and secure your sensitive data against quantum threats. The free tier includes ML-KEM-512 + X25519 hybrid encryption, AES-256-GCM, and Argon2id key derivation. No account required.

Migrating a database, replicated store, or cold-storage archive off classical cryptography is a separate engagement. See Professional Services.
