NodeJS Packet Function

Thought I would release this to help you out

Since NodeJS is so popular and cross platform thought you would need it you can use this to decrypt and send the packets

Code:

function EncryptDecrypt(data) {
    let numArray = Buffer.from([ 250, 158, 179]);
    for (var i = 0; i < data.length; i++) {
        if (data[i] != numArray[i % numArray.length]) {
            data[i] = (data[i] ^ numArray[i % numArray.length]);
        }
    }
    return data;
}

function SendMessage(message, type=255, cmd=255){
    message = Buffer.from(message);
    let length = message.length;
    let bArray = Buffer.alloc(length + 3);
    bArray[0] = type;
    bArray[1] = cmd;
    message.copy(bArray, 2);
    EncryptDecrypt(bArray);
    bArray[length + 2] = 0;
    return bArray;
}
