## Summary
The ZUPT backup, compression, and data protection utility has been accepted into openSUSE Factory. The tool integrates file archiving, compression, and integrity verification with advanced security features. Notably, it employs a hybrid cryptographic scheme combining ML-KEM-768 and X25519 to protect against future quantum computing threats.

## Technical features of ZUPT
- Uses a hybrid cryptographic scheme: **ML-KEM-768 + X25519**.
- Implements **AES-256** based encryption.
- Supports multithreaded processing for backup, compression, and restore operations.
- Includes built-in file integrity verification to detect data corruption or modification.

## Why it matters
The integration provides openSUSE users with a specialized tool to mitigate 'harvest now, decrypt later' risks for sensitive, long-lived data.
