JEB 打开apk

找到MainActivity,按table 反编译出来源码

看看看，然后写出解密程序

1 def getCodesFromPic(): 2      3     with open('logo.png','r') as f: 4         v0 = f.read() 5     return v0[89473:89473+768].decode('u8'),v0[91265:91265+18].decode('u8')        6  7 def aliCodeToBytes(codeTable,strCmd): 8     pwd = '' 9     for i in strCmd:10         pwd += chr(codeTable.find(i))11     return pwd12 13 if __name__=="__main__":14     table, pwdCode = getCodesFromPic()15     print table, pwdCode16     pwd = aliCodeToBytes(table, pwdCode)17     print pwd

运行得到密码
