    日本語の説明は こちら

    nandokujs is an obfuscation tool for obfuscating javascript files to be published on the Web and making it difficult to analyze the contents.

    You can make your keycode mandatory for running javascript files, with your own tally code.

    In this way, javascript files are obfuscated, so important logic is not exposed to the Web in plain text.

    Installation

    ※ It is assumed that nodejs is installed and npm can be used.

    $ npm install -g nandokujs

    How to use

    The usage can be confirmed by executing the command.

    Files obfuscated by nandokujs are output as [js file name].nan.js.

    $ nandokujs -j [js file name] -m [execute eval] -t [tally code] -o [out file]
      -j (--js) [js file name]  Set the js file name to be converted.
      -m (--mode) [execute eval] Set the expansion condition.
          When [true] Expand obfuscated information with eval
          [false] Extract obfuscated information with location = `javascript:`
          If not used, [true] is set.
      -t (--tally) [tally code]  Set tally code.
          html side js call (<script src='target js'></script>)
            <script> var _$tallyCode = 'tally code'; </script>
          Define.
          If you do not use it, please do not set it.
      -o (--out) Set the output file name of nandokujs.
      -v (--version) Version information will be returned.
      -h (--help) Help information will be returned.
    
     Files obfuscated by nandokujs are output as [js file name].nan.js.
    

    -j or --js Set the javascript file you want to convert.

    -m or --mode Set expansion conditions.

    When [true] Expand obfuscated information with eval.
    
    [false] Extract obfuscated information with location = "javascript:".
    
    If this setting is omitted, it will be treated as [true].
    As a reason to do this setting, there are cases where you do not want to
     extract obfuscated information in eval, but you want to expand it with 
     location = "javascript:".
    
    For example, when an error occurs during eval execution.
    It is used in such a case.
    

    -t or --tally You can optionally set the Tally code.

    In that case, it is necessary to code as follows for the javascript 
     caller to publish on the web.
    
    <script>
      var _$tallyCode = "tally code";
    </script>
    <script src="[target javascript].nan.js"></script>

    -o or --out Set the output file name of nandokujs.

    -v or --version Display the version.

    -h or --help Display help information.

    exsample

    Obfuscation with command.

    $ nandokujs -j cbox-min.js -t test

    The following call is described in html using js file.

    <script>
      var _$tallyCode = "test";
    </script>
    <script src="cbox-min.js.nan.js"></script>

    Finally

    With this tool, I hope to be a good deal for web development.
