I want to scrape data via a mobile app interface, unfortunately there is a signature parameter. I tried to decompile a andorid app, The frustrating thing is that the signature algorithm is not written by Java(So couldn't view the source), it's in a external library (a libencrypt.so file).
The encrypt fuction takes a array as input.
['', '4314', 'PEK', 'PVG', '2016-04-07', 'MU5183', '1459997456991']
e.g. The above input will gemerate a hash result(the signature parameter): 'c7802d46'
Now i just want to touch my luck. Is there any well known signature(hash) algorithm generating 8 bytes long string as this?
