It’s clearly a python compiled program since there is a libpython and also, when using decompiler, there was a function name PyDontWriteByteCode
using ‘pyi-archive-viewer’ we can extract the main function.
Append headers to the file
"\x03\xf3\x0d\x0a\xf1\x32\x75\x5a"
using uncompyle, we can get the main function.
Change the key a little bit ±k*360 and we will get the flag.
