计算obb hash的python方法
#!/usr/bin/python
#coding: utf8
import os
import sys
print(str(sys.argv))
obb =sys.argv[1]

unity 会记录打出来的obb的hash在/assets/bin/Data/settings.xml 。修改obb或者想复用obb就需要修改apk内的hash字段。 用obb的最后65558个字节计算的hash
public static string CalculateObbDigest(string file)
{
byte[] arrayOfByte = null;
using (var localMessageDigest = MD5.Create())
using (var localFileInputStream = File.OpenRead(file))
{
long l1 = localFileInputStream.Length;
localFileInputStream.Seek(l1 - Math.Min(l1, 65558L), SeekOrigin.Current);
arrayOfByte = localMessageDigest.ComputeHash(localFileInputStream);
