Solution by elprofesor: Using ghidra. You have a pdf file with info about how i found the logic behind and some info about the keygen. Also I attached a keygen.py script. Cheers!

Basicly, u need to debug this code and watch what happens with variables.
The tricky one is that in first "if" we compare with hex 0xA (10 in dec), but then, in second "if" we sum up "v3" with decimal. So, that's all. Very nice for beginner.
