Disclaimer: I didn’t write this, I do not have access to the source code, and I also didn’t audit anything.
I simply spent the last 3 hours looking for a working download of the tool for Linux, and now that I finally found one, I want to make it easier for others in the future.
kageru/axon7tool-linux
Just a binary of the axon7tool for Linux. I searched the internet for 3 hours looking for it so you don’t have to.
