[Automation-Scripting]002.cocos2dx-lua LUA code Windows encryption batch

In the development of software, we will be in the project when the code is encrypted, to prevent the theft of criminals to profit. Different languages have different encryption methods, more famous are Packers, code confusion and so on. when Lua develops COCOS2DX , the framework will have scripts that provide encryption . Let me talk about the steps to encrypt Windows

1. To know the storage path of the source code to be encrypted, and specify the backup path

2. Copy the code to the backup path

3. Go to BOM processing for all scripts

4. Use PHP command compile_scripts.php for encryption processing.

According to the above four points, we post the UTF8 to the BOM code and the whole code of encryption

1.utf-8

#! /usr/bin/python#-*-coding:utf-8-*-import osimport sysimport codecsdef convert (dirname, filename): if Os.path.splitext (filename) [1] in ['. txt ', '. Py, ', '. Lua ', '. Sh ']:p ath = os.path.join (dirname, filename) print ' converting%s '% (path) f = open (path, ' r B ') content = F.read (3) if content! = ' \xef\xbb\xbf ':p rint '%s is not utf-8 BOM '% (path) returncontent = F.read () f.close () F = Open (Path, ' WB ') f.write (content) f.close () print ' Convert%s finish '% (path) def useage (): If Len (sys.argv) = = 1:print ' Useage:utf8 file or dir ... ' return truedef Exist_error (f): If not os.path.exists (f):p rint ' ERROR:%s was not exist '% (f) return Truedef main (): If Useage () : Returnfor F in Sys.argv[1:]:if Exist_error (f): Breakif Os.path.isdir (f): For Root, dirs, files in Os.walk (f): For I in Files : Convert (root, i) Else:convert (", f) if __name__ = = ' __main__ ': Main ()
