Senbei is a research and interoperability tool for lawful reverse engineering, security research, and preservation of software you already legitimately possess. Only process binaries you own or are explicitly authorized to analyze.
Circumventing technological protection measures may be restricted in your jurisdiction (for example under DMCA §1201 in the United States, which contains exemptions for security research and interoperability). Ensuring your use is lawful is your responsibility.
Senbei performs a purely static transformation of files on your device: it bypasses no access control by itself, ships no keys and no vendor code, and uploads nothing — everything runs locally in your browser. Do not redistribute decrypted outputs. This software is provided “as is”, without warranty of any kind; the authors accept no liability for misuse. “Crackproof” is a trademark of its owner; this project is not affiliated with or endorsed by the vendor or any publisher.
Static unpacker for Crackproof-protected PE files, running entirely in your browser. No file ever leaves your device.
