研究方向
Investigate the Zip operation implementation in CyberChef, particularly the password handling in the encryption process. Reproduce the bug with a sample file and known password. Check if the issue is in the underlying library (e.g., zip.js) or in CyberChef's integration. Look at related issues or closed PRs for clues. The maintainer may need to clarify the expected behavior and provide a concrete test case.
