As a Roblox developer, it is currently too hard to obfuscate our local scripts. Would it be possible to make an option to remove debug data from the bytecode of local scripts? Maybe with the exception of line numbers. Was it ContextLost that vaguely mentioned the idea or polled us on it a year or two ago? It would be nice if local scripts were replicated to clients as some form of minified Lua byte-code outside of testing.
You can still recreate the script but it increases the difficult tremendously. Right now we only send encrypted bytecode to the client. The client is not even capable of compiling Lua code, it can only execute already-compiled bytecode.
The problem is that Lua bytecode maps almost to the original source code form, including line numbers, the names of local variables, and other stuff. You lose quirky indentation and comments and maybe do blocks as well, but you retain almost everything else.
Really something to be proud of.Ethanol extraction method
Any website works the same way. Anyone can see the client code. Sure, it might be obfuscated, but can easily be converted into readable code.
And usually this obfuscation is more-so minification for the sake of smaller download sizes. But then, why not just give out the roblox source code and make it easy to hack the client? Encrypting it would make it not only difficult for you to debug, but also for Roblox engineers to debug crashes that may be caused by something in your code.
Note that this would still allow for Lua decompilation, it just would be somewhat less useful without the local names.
We could also theoretically send scripts as is to clients that are from the group that owns the game, so that the major usability impact is for error reports from other players, not from your own testing.

Aha, that did the trick, thanks! All are pretty good. Ironbrew is more focused on speed, Xen is more focused on security, while Luraph is a middle ground between the two. Your choice, pretty much. Is there any freely available solution?
Xen does appear to be linked to a Roblox exploit. What is your reason for wanting to obfuscate code? It generally has more drawbacks than benefits:. Due to private modules being removed. Doubly true if it includes instructions to enable HttpService to access some kind of whitelist or authentication server. That just gives anyone who de-obfuscates your module and finds something exploitable a nice directory of which games they can leverage the exploit in.
Indeed, I understand that. The module is communicating with our endpoints on our servers. Abusers spammed that endpoint. We have an idea to create an open-source model, using keys that could be generated using a portal. What is a good script obfuscator for modulescripts?

Help and Feedback. Scripting Support. Autterfly February 5,am 2.Obfuscate doesn't result in a string of alternating commas and digits like you seem to be assuming it does. It doesn't form any nice pattern, and since Lua doesn't provide a split method, you won't want to implement it the way you are. While it's not related directly to your question, I would like to point out that doing obfuscation in this form is futile.
Since everything has to be piped through some function like Deobfuscate to run it, whoever wants to discover the original just has to change loadstring or whatever other evaluation to print.
Successful code obfuscation requires that the code runs as it is, without having to do some post-processing on it. Sign Up Log in.Vgg16 pytorch code

I paid an untrusted developer for a script. And as I thought he scammed me. He did send me code, but he obfuscated the script.
It is for a game called "Roblox" that uses Lua, the code will be down below. As from I can tell by running it, it might work. But I would need to change the script for it to work. Does anyone know to to decode the obfuscation?

Ok so I am turtsis and I see that people have been stealing my answer and posting it on v3rmillion as there own. So I will post another answer but this time a better one on how to actually get contents of it. Luraph is a custom lbi which is a lua bytecode interpreter. If you do string. That is why people use unluaC or luadec to get the source to these dumps. This is called bytecode which is different then string:byte as it is a non readable lua format in lua 5.
What a lbi does is it interpreted the bits and deserialzes them.
[Obfuscation] How do I Deobfuscate the Obfuscated code correctly?
In lua and other coding languages there is things called opcodes. Opcodes control the base of lua and there is quite a few of them. Some of the most commonly known and most useful ones are these:.
Ok so to get those normally you would need a external program called unluac or luadec but for this we will be doing it in base lua. I recommend using repl.
Now you probaly have heard of iron brew and synapse xen both are very known lua obfuscators created by 3ds and Defcon But they have a table that has all the constants in them xen is encrypted to get these tables there is a whole process with table.
Luraph is different Though because it is a lbi so there is no need for a table with all the constants in it. Instead to get the constants we need a way to get the instructions from a script. Opcodes are instructions. They are instructions because opcodes tell lua what to do with code.
Ok so how do we get these instructions? Now different obfuscators have different opcodes instructions so for luraph you will have to find them. You will need to go onto repl. Where in the settings it has opcodes you will need to manually get these from luraph. If you need more help dm me on discord: turtsis Or turtsis So you will need to rename the variables and functions into something like variable1variable2 so that you are able to read it.
Then find parts that are junk code like. Which are completely useless and are meant to trick decompilers into looping random number functions.Forums New posts Search forums. What's new. Premium. Chat 0. Log in. Search Everywhere Threads This forum This thread. Search titles only.Ptv pakistan

When i turned 14, i got hearing aids. I got BTE hearing aids behind the ear and just recently i got in-canal hearing aids. So, these kinda look like the galaxy bud things that Samsung released. Once i got them, i was a lot less conscious of them. So, when i went to school with them on, nobody really seemed to notice.
During 2nd period, i put my hair up cause my art class was using acrylic paints. So, this kid who was walking past me to refill his water cup, stopped, looked at me and tapped me on the shoulder. Me, obviously confused, took a second to process what he just said.Airsep focus portable oxygen concentrator price
I kinda need them to, you know, hear". He was embarrassed. He just kinda I'm not really sure how to put it. This happened about a year ago. I made a phone call and ordered two pizzas from dominoes. So the other day I was watching this documentary on Netflix. Just as it's finishing I message my mum recommending it to her as I felt it was something she would like.
She replied saying she has 4 minutes left on the show. I look down and see I have 3 minutes and 58 seconds remaining. She lives km away from me and we didn't speak before hand. We had both decided to watch the exact same documentary within 5 seconds of each other!
I'm still spinning out about this. My first job after college was as a math teacher. Aside from flipping bottles and dabbing to give you a sense of the time periodmy students actually engaged in some shenanigans that my generation which wasn't too far off from theirs obsessed over: slap neck. You know One of my students "got me," and my instant reaction was to yell "self-serve.
Despite my attempt to regain order, I would NOT look at their hands. Hell no. They weren't going to get me again. Need help with a problem? Slide the paper over and walk away I got caught a couple of times and even let some of my student slap my neck. No issue. I'd get them all back. A test was coming up and I was reviewing the material with them via a projector.
We got to the last problem and I told my students that what I'm about to show them is super important, but that I will only show the entire class if everyone is looking at the board.
