Lightweight post-quantum file encryption for command-line users
Encrypts files using a hybrid post-quantum scheme, supports key rotation without re-encrypting large payloads, and compresses data before encryption for storage efficiency. sindook, by Ruddro Roy, is distributed as a single-binary CLI for Windows and automation workflows. It implements X25519 paired with ML-KEM-768, offers recipient management and portable operation, and targets security-conscious users, developers, and IT professionals who need future-proof local encryption.
It implements hybrid post-quantum cryptography for long-term secrecy
Mechanics: the tool combines X25519 with ML-KEM-768 (marketed as X-Wing) to produce a hybrid key-exchange layer that protects payload keys against conventional and post-quantum attacks. The program performs compression before encryption and packages everything in a single binary, so the encryption step is the final output written to disk. The command-line invocation accepts input files and writes the encrypted artifact to the specified path.
The tool is designed for low-footprint automation and scripted workflows
Operational profile: the CLI-focused distribution prioritizes speed and portability: a single-binary layout removes runtime dependencies, which simplifies deployment across Windows systems and scripting environments. Built-in compression reduces payload size before cryptographic processing, and the key rotation mechanism updates recipient access without reprocessing large datasets, which reduces time and I/O during maintenance tasks.
Security model and who can operate it safely
Safety and trust signals: the project is open-source under Apache-2.0, enabling code inspection and integration into controlled toolchains. The hybrid approach yields quantum-resistant key exchange, and the recipient-management layer supports administrative workflows for access updates. The command-line surface means administrators and developers get granular control, while less technical users will need CLI familiarity to avoid mistakes.
Practical for administrators who accept a command-line workflow
Sindook suits security-conscious administrators and developers who require long-lived, local encryption with manageable operational overhead; expect a learning curve for CLI usage and plan key-management steps before broad deployment. Test workflows in a sandbox environment to validate automation and access updates prior to production rollout. Recommended.
