Verify release executable file

[cage2]

Hi!

Sorry if this question has been already asked but I was not able to find information elsewhere.

I would like to make an appimage for a software and i believe appimage-buider is the simplest way to build it. I downloaded the release file from this page:

https://github.com/AppImageCrafters/appimage-builder/releases/tag/v1.1.0

But now i would like to verify the package's signature and i can not find a signature file in the page above. Moreover seems to me that the package does not embeds a signature (--appimage-signature returns nothing). Maybe I am doing something wrong, but i can not figure out how to check the package integrity and if it comes from the right source.

Thanks in advance! C.
