SIGNATURE / ARCHIVE ENGINE / UNPACK V1.0

See first.
Extract second.

UNPACK audits a ZIP before anything is written: path traversal, encryption, executable-like entries, extreme compression ratios and duplicate normalized paths. Select exactly what you need, verify every extracted file with CRC32, then save to a folder or export one clean ZIP.

01 / AUDITArchive before extraction.

Central-directory data is inspected locally first. Unsafe or absolute paths are normalized and blocking signals are visible before a write is attempted.

02 / SELECTTake only what matters.

Safe entries are selected by default. Review items such as scripts, executables or OS metadata stay visible but require an intentional choice.

03 / VERIFYCRC before delivery.

Every selected entry is extracted individually within browser memory limits and must match its declared size and CRC32 before it is handed to the user.

04 / DELIVERFolder when possible, ZIP everywhere.

Supported desktop browsers can save directly into a chosen folder. Everywhere else, selected entries can be re-packed into one clean portable ZIP.
