I am little bored and I though I would try something.
I was wondering how I could hide a string in js file. So I build a tool that would create a shuffling array and insert the string in there.
Then I would scatter the buildering of the string in different files, and building it again.
Now I though about it and could not help but wonder is this necessary when using it in react-native and react
here have a look and tell me what you think
const shuffle= (text, tohex) => {
function ConvertStringToHex(str) {
var arr = [];
for (var i = 0; i < str.length; i++) {
arr[i] = ('00' + str.charCodeAt(i).toString(16)).slice(-4);
}
return '\\u' + arr.join('\\u');
}
function shuffleArray(data) {
let array = [...data];
for (var i = array.length - 1; i > 0; i--) {
var j = Math.floor(Math.random() * (i + 1));
var temp = array[i];
array[i] = array[j];
array[j] = temp;
}
return array;
}
const strArray = []
for (let i = 0; i < text.length; i++) {
const c = tohex === true? `'${ConvertStringToHex(text.charAt(i))}'`: `'${text.charAt(i)}'`
const name = `v${c.replace(/'|\\/g, "")}l`;
strArray.push({
index: strArray.find((x) => x.name === name)?.index | i,
name: name,
file: !strArray.find((x) => x.name === name)
? `${c}`
: '',
});
}
const variable = "_0x" + Math.floor(text.length * (Math.random() * text.length))
const data = strArray;
var shuffledData = shuffleArray(strArray.filter((x) => x.file !== ''));
let rClass = 'const ' + variable +'= [' + shuffledData.map(x=> x.file).join(",")+"]";
rClass += `\nexport default ${data.reduce((arr, v) =>{
var item = shuffledData.findIndex(x=> x.name === v.name);
if (item !== -1)
arr.push(variable+`[` + ('0X' + item.toString(16).toUpperCase()).slice(-4) +"]" )
return arr;
}, []).join('+')}`;
return rClass;
};
const ts = "kjhasd ";
console.log(shuffle(ts, false))Now the idea is that export default _0x19[0X1]+_0x19[0X0]+_0x19[0X3]+_0x19[0X2]+_0x19[0X4]+_0x19[0X6]+_0x19[0X5]
wont be in one file but in many other files with different imported names., that will be scattered, and then combined to one result string. This will make sure that others wont be able to read the string when opening the bundle js
