cocos2dx lua已经集成了对lua脚本的加解密，见AppDelegate.cpp.
- LuaStack*stack=engine->getLuaStack();
- stack->setXXTEAKeyAndSign("123",strlen("123"),"cloud",strlen("cloud"));
好，我们来对文件加密。打开cocos2d-x\external\xxtea文件夹，调用相关函数xxtea_encrypt进行加密，最后在文件开始位置，写上签名就可以了。我把相关操作封装成一个python文件。可以直接调用。
- importxxteaModule
- importos
- defReadFile(filePath):
- file_object=open(filePath,'rb')
- all_the_text=file_object.read()
- file_object.close()
- returnall_the_text
- defWriteFile(filePath,all_the_text):
- 'wb')
- file_object.write(all_the_text)
- defBakFile(filePath,all_the_text):
- file_bak=filePath[:len(filePath)-3]+'bak'
- WriteFile(file_bak,all_the_text)
- defListLua(path):
- fileList=[]
- forroot,dirs,filesinos.walk(path):
- foreachfilesinfiles:
- ifeachfiles[-4:]=='.lua':
- fileList.append(root+'/'+eachfiles)
- returnfileList
- defEncodeWithXxteaModule(filePath,key,signment):
- all_the_text=ReadFile(filePath)
- ifall_the_text[:len(signment)]==signment:
- return
