find way to show mystery added bytes in APKs
We're getting 2-8 byte diffs in ZIPs that are Android APKs and can't really find a tool to reliably show us what the actual diff is. Basically, we try to follow the Android apksigner algorithm (written in Java), but implemented in Python, and we get these diffs.
zipinfo -v seem to show them as compressed size differences, but I'm pretty sure that's wrong, since the ZIP comprssion algorithm is deterministic and we're using the same settings in Java and Python.
I wonder if anyone knows a tool to show this diff in a useful way, and if so, can it be included in diffoscope? I can see something using vbindiff but I haven't really deciphered it.
