xyz.app is damaged and can not be opened

[TommySlokky]

Configuration

• Keka version: [e.g. 1.3.8 (5320)]
• macOS version: [e.g. 11.7.10

I have a codesigned app. I zip it using Info-Zip commandline. If I unzip using same commandline OR using builtin macos "Archive Utility" my app works.

But if Keka unzips it, then opening the app gives error:

"xyz.app is damaged and can't be opended. You should move it to Bin.

Keka created this file on an unknown date."

Is there any way to solve this from my side? Or is this a Keka bug? Let me know if you need more information.
