Post Quantum Cryptography (PQC)

Today's widely-used public-key cryptographic schemes, such as RSA and elliptic curve cryptography, rely on mathematical problems like integer factoring and discrete logarithms. Future quantum computers could efficiently solve these problems, placing long-term data security at risk.

To address this, the National Institute of Standards and Technology (NIST) has standardized new post-quantum cryptographic algorithms designed to withstand both classical and quantum attacks. These include the Module-Lattice-based Key-Encapsulation Mechanism (ML-KEM) and the Module-Lattice-based Digital Signature Algorithm (ML-DSA), which are based on mathematical foundations believed to be resistant to quantum computing threats.

Our Approach and Plans

Files.com supports the global transition to quantum-resistant encryption standards. These algorithms are now standardized, but adoption across the broader ecosystem, including browsers, operating systems, and file transfer clients, remains limited.

Files.com will launch PQC support across the platform, covering encryption in transit via HTTPS, FTPS, SFTP, and other endpoints, as soon as ecosystem support is sufficiently mature. The implementation will follow NIST-approved algorithms and industry best practices for performance, compatibility, and long-term trust.

Files.com will continue to support legacy ciphers where compatibility is required. Customers have per-account configuration options to tailor the balance between PQC readiness and legacy compatibility.

There is no specific target date for PQC deployment. Files.com will move in lock-step with the major client, protocol, and library vendors driving adoption, so customers gain PQC capabilities as soon as they become viable and broadly interoperable.

For encryption at rest, Files.com uses Amazon Web Services (AWS) encryption capabilities. AWS has publicly committed to supporting PQC, and Files.com will transition to this tooling for encryption at rest once it is available. As part of that transition, Files.com will re-encrypt existing data as quickly as practical.
