openSUSE Adopts ZUPT for Post-Quantum Backups

The openSUSE team has announced it is making the ZUPT utility available in its Linux distribution as a solution for post-quantum backups. ZUPT is an open-source tool that rolls several functions into one: backup creation, compression, integrity verification, and encryption.

Protection with the future in mind

The standout feature of ZUPT is its cryptography. The utility supports AES-256-based encryption as well as a hybrid scheme built on a combination of ML-KEM-768 and X25519. The developers' bet is that backups made with ZUPT will remain secure even against future cryptographic threats arising from advances in quantum computing.

Performance and integration

To speed things up, ZUPT taps into CPU multi-threading across every stage — backup creation, compression, and encryption alike.

The utility has been accepted into openSUSE Factory, becoming an "officially integrated solution" that spans the entire life-cycle of system backups — from compression to encryption protection — within the openSUSE ecosystem. Further details are available on the project's GitHub page as well as the openSUSE news portal.
