QCS provides a post‑quantum file format (.qtm) that embeds NIST‑standard Kyber key exchange and Dilithium signatures, enabling secure multi‑recipient encryption, offline verification, and built‑in audit metadata. The self‑contained container supports air‑gapped and sovereign deployments, helping regulated organizations protect long‑term records against future quantum attacks.

Problem
Current digital document formats (e.g., PDF, ZIP, CMS) rely on cryptographic algorithms that will be broken by future quantum computers, exposing long‑term confidential data to “harvest‑now, decrypt‑later” attacks. Organizations in regulated sectors must protect records for decades, but existing solutions lack built‑in quantum‑safe encryption, offline verification, and sovereign key management.
Solution
QCS delivers a self‑contained post‑quantum file format (.qtm) that embeds NIST‑standard PQC algorithms—Kyber for key exchange and Dilithium for digital signatures—directly within the archive. The format bundles the payload, cryptographic material, access‑control policies, and audit metadata, enabling encryption for multiple recipients, offline integrity verification, and key lifecycle management without external services. By operating on air‑gapped or sovereign environments, .qtm ensures that encrypted data remain confidential and verifiable for decades, meeting regulatory requirements such as NIS2, ENS, DORA, and eIDAS2. The solution is offered through an open‑core SDK and optional premium extensions, allowing integration into existing workflows with minimal cryptographic expertise.
Target Audience
Primary customers are regulated organizations—law firms, hospitals, financial institutions, and public‑sector agencies—that must secure long‑term records against future quantum threats.
Features
- Integrated Kyber key‑exchange and Dilithium signatures within a single .qtm container
- Multi‑recipient (pool) encryption allowing a single file to be securely shared with many authorized parties
- Embedded access‑control policies, audit trails, and TLV metadata for traceability and retention compliance
- Offline verification and decryption using locally stored private keys, eliminating reliance on external services
- Air‑gapped operation mode supporting sovereign deployments with no vendor lock‑in
- Open‑core SDK for easy integration; premium modules provide enterprise key‑management and cloud‑connector capabilities
