libzupt, a new post-quantum cryptography SDK, has been officially released as a package in the openSUSE ecosystem (Leap and Tumbleweed). The library implements a hybrid ML-KEM-768 + X25519 approach for file and in-memory encryption, standardized by NIST in August 2024. It currently supports C++, Python, and Java (Node.js in development), aiming to make post-quantum cryptographic mechanisms accessible to developers. The library originates from the Zupt backup/compression project and is designed to help applications remain secure against future quantum computing threats such as Shor's Algorithm.
