A program to turn JS source files into proper garbage consisting only of symbols but produces the same output when run by a javascript interpreter like node or a browser.
The output is the same filename as the input, but prefixed with BS_. If such a file exists, it is overwritten in place.
To build:
makeTo run
./main myJavascriptScript.jsThen execute the transpiled script
node ./BS_myJavascriptScript.jsNode does not recognize fs or the requires keyword in the obfuscated script. If you need to pass parameters into the script then
- Write the script as though the parameters exist already and transpile it.
- Then open the transpiled scriptfile with a text editor. Insert your code above and below the BS script.
- The BS script will always start with
(()=>{})[. Find the matching bracket to the[and insert after that your parameters as strings. - Pass your parameters at the very end into the function call.
It's unlikely that I add options to include such things automatically. PRs welcome though.
For example
let myVar = 42;
(()=>{})[ ... ]('myVarIdentifierAsUsedInTheBSScript', ... )(myVar)
You can also obfuscate that first string, too, by creating a file with just the variable identifier and then pasting that in after mangling it. Just remove the quote marks.
This was shamelessly 'inspired' from here, but rewritten in c++:
