So it would look something like this: It seems that the goto answer for this is Cython. That means they didn't make much money anyway, so why bother. link to Design by Contract Hinges on Implication, the different ways you can support the site, Violent Python: A Cookbook for Hackers, Forensic Analysts, Penetration Testers and Security Engineers, Black Hat Python: Python Programming for Hackers and Pentesters, How to Compare Strings in Python: Equality and Identity, How to Perform a Reverse Dictionary Lookup in Python: Generator Expressions and More, Python Code Snippets for Everyday Problems, Remove comments, type hints, and whitespace. In this article, well take a look at a few ways of making this code snippet as unintelligible as possible. How to obfuscate python code to be compiled to an executeable? You cannot copy a service, pirate nor steal it. Do you just want to encode the file so that you can decode it later (by the command line, say)? This will also speed up the program. Regarding the WingIDE business model: Support is a service, software a product. Also, some open-source licenses prohibit you from concealing the source or origins of that component. Is there a good way to handle this problem? What are you trying to hide? It's the professional hackers that you will not likely beat. Heres a standalone function that I pulled from my auto-grader project. Edit: You can use following code to prevent cache directory generation: It seems that the bytecode could be easily uncompiled using. So they will not steal your work but work with you to improve it. so, it doesn't generate any file in running time, which now makes sense to me. This function will restore those obfuscated bytecode between offset 3 and n, and put the original byte-code at offset 0. To add a bit of chaos, I thought it would be fun to insert a whitespace character: Then, we can call the strip method to remove that extra space. This is basically un-reversable, compared to .pyc bytecode! You might be able to build a single executable if you can link to (and optimize with) the python runtime and all libraries (dlls) statically. you may create table of values which are used by program logic, but also used as signature), which can be used to determine that code is originated from you. Please help us improve Stack Overflow. The approach - opcode remapping is a good barrier, but clearly it can be defeated. Did Paul Halmos state The heart of mathematics consists of concrete examples and concrete problems"? Newer versions of Windows are cracked every time. A Python script to obfuscate and protect your code through anti debuggers, junk code and custom encryption. Chances are that they will contact you and so you will learn about the reselling of your work. Did I give the right advice to my father about his 401k being down? Add the flags --onefile or -standalone if this works to get a package for distribution. Of course, the casual reader doesnt know that. (You could of course wrap multiple py scripts in bash/batch, but I think a pure python solution is ideal). Now if you see the folder containing our actual utils.py file, a new subfolder will be created called dist. Find all the variable names by looking at method signatures and the left-hand-sides of assignments, and all the import aliases. @S.Lott, I believe point 6 holds more importance based on the question. Gets it out there in a huge way and massive market share, then you have a very big customer base for support and addons. Pyarmor. With the comments out of the way, we can begin removing other helpful pieces of syntax. [duplicate]. It protects Python scripts by the following ways: Obfuscate code object to protect constants and literal strings. If there are many calls to the extension, it could be difficult to eradicate. I might not be sad, because I never knew, but I still have less money then if B had kept the promise. This output corresponds to a 40-line original input script as shown here. If newsletters aren't your thing, there are at least 4 other ways you can help grow The Renegade Coder. In line with this the source of Opy is not obfuscated. The Renegade Coder is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. To compile, you could then use something like PyInstaller or py2exe in order to create a stand-alone executable. Even if you use a exe-packager like py2exe, the layout of the executable is well-known, and the Python byte-codes are well understood. You can package the obfuscated Python files into an executable for distribution using the . How do I split the definition of a long string over multiple lines? I think, if we have a frequency - how often expensive obfuscated code is hacked - we could say about practicability of using Python and obfuscated code. Is it possible to hide code in my importable package? "Is there a good way to handle this problem?" Maybe looking at how you can benefit from the situation would yield a better return of your investment than fearing how much you could lose. Connect and share knowledge within a single location that is structured and easy to search. The only problem with jython is that you can't use python modules written in c. You should take a look at how the guys at getdropbox.com do it for their client software, including Linux. Offer it as a web service. I find it a little contradictory to leave the source or opcodes open for eyeballs, but use SSL for network traffic. - use compiled bytecode (python -m compileall) For example, we have a few bits of syntax which help people track variable types throughout the code. In other words, u corresponds to 117, t corresponds to 116, f corresponds to 102, and 8 corresponds to 56. Possible techniques discussed are: I also don't think it is not a problem as long as you deploy the code in your own server (providing software as a service). first time, from the wrapped bytecode descripted in above section, we If you want to really protect and sell your code, consider adding an actual license with an embedded virtual date on it. Nowadays, business models tend to go for selling services instead of products. Another aspect is that my employer does not want the code to be read by our customers, fearing that the code may be stolen or at least the "novel ideas". Type 'opy ?' or 'python opy.py ?' (without the quotes) on the command line to display a help text and a reference to the licence. At this point, what is stopping us from writing a completely ridiculous dead block? A basic way to obfuscate your code is to simply rename all your named parameters (variable names, dictionary key names, all names that have a meaningless assocation with the data they hold; be creative). More information about what is present in the compiled binary: Most of the limitations you mention aren't really correct - there's extra syntax that adds statically typing (mainly for speed) but most normal Python programs should run unaltered, including keyword parameters, conditional imports. Offer significant value. (a) Write the critical pieces of the code as C or C++ libraries and then use SIP or swig to expose the C/C++ APIs to Python namespace. Try pasting your hello world python code to the following site: http://enscryption.com/encrypt-and-obfuscate-scripts.html. Is your employer aware that he can "steal" back any ideas that other people get from your code? Then, what is the point of all this? Note that I pointed out that has drawbacks. To do that, well need some piece of nicely formatted source code: Cool! semiuseless: I suspect 30 lines of code isn't going to be hidden that well in C, either. Beyond that, Im aware that there are obfuscation tools out there, but Im not sure how widely used they are. Concentrate on making your code as nice to use as possible - having happy customers will make your company far more money than preventing some theoretical piracy.. Another attempt to make your code harder to steal is to use jython and then use java obfuscator. What does the "yield" keyword do in Python? 11 minute read. I was surprised in not seeing pyconcrete in any answer. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. Programmers may deliberately obfuscate code to conceal its purpose (security through obscurity) or its logic or implicit values embedded in it, primarily, in order to prevent tampering, deter reverse engineering, or even as a puzzle or recreational challenge for someone reading the source code. What is the cause of the constancy of the speed of light in vacuum? This has the makings of a great answer if more explanation was added. Internet: "No. Cython, Shed Skin, and PyPy go beyond bytecode. Really? As with most articles in this series, I was doing some browsing on Google, and I found that some folks had an interest in learning how to obfuscate code in Python. Javascript JSPython,javascript,python,cryptography,web-scraping,obfuscation,Javascript,Python,Cryptography,Web Scraping,Obfuscation,pythonweb function obfuscateText(coded, key) { // Email obfuscator script 2.1 by Tim Williams, University of Arizona // Random encryption key . Also if you have a lot of .py files to import or as dependency, you must use the recursive command line instead of restrict command for your code to work. That way, you can roll this directly into a more encompassing packaging script. I also used pyarmor referenced here, but the pytransform.so or pytransform.dll shared object which is the core of pyarmor is closed source, which was a blocker in my project. It's always possible to bypass the signature-checking loader. I believe there was a game like Mount and Blade or something that changed and recompiled their own python interpreter (the original interpreter which i believe is open source) and just changed the OP codes in the OP code table to be different then the standard python OP codes. As a result, the code is still fairly readable. But if you wish to modify the original utils.py code, then you have to start from step 1 and follow the same steps to do so. Good obfuscation adds basically the same protection to your code, that compiling it to executable (and stripping binary) does. Obfuscating python code just doesn't really mesh with the language. - don't quote me on that, i want my python file [all the code lines is encode ] i mean all the file is encoded !! As a result, treat this like a fun thought experiment. Signing does not work in this context. Obscure your constants inside a class/module so that help(config) doesn't show everything, First compile python script to code object, Then iterate each code object, obfuscate co_code of each code object as the following, Save obfuscated code object as .pyc or .pyo file. Offer customization at rates so attractive that they'd rather pay you to build and support the enhancements. But beware, because that only works for people that are less intelligent than you! How do I protect Python code from being read by users? So the more people asking "how to protect Python app" only promotes that development. How are we doing? So if you include the source (with a license that protects you from simple reselling), chances are that they will simply push back changes they made since that will make sure the change is in the next version and they don't have to maintain it. Developed and run in Visual Studio Code, this is a basic python program to obfuscate C/C++ files. Since you gain access to individual AST nodes, using this approach allows you to perform arbitrary modifications to the source file. Add a description, image, and links to the The first code hardening technique that should be applied in every case is to get rid of everything in your code that's not necessary. This will not help preventing hacking of your program. This is a tool to obfuscate / to make your python code unreadable. You could embed your code in C/C++ and compile Then, you could generate new names without any worries about clashes. If someone decides to use your obfuscated code module as part of their own product (even after reobfuscating it to make it seem different) you can show, that code is stolen with your secret signature. In other words, we decide what we name our functions and variables. Even if the license-checking code were hard to reverse engineer because it's written in C, wouldn't it still be relatively easy to remove the calls to the license-checking code? What is dependency grammar and what are the possible relationships? Keep in mind that anyone who has the script can decode the text back into human readable python using the same base64.b64decode function. Is there a way to hide a line of code in Python? 1.

For instance, you could always add a logger which prints erroneous messages to the console. If you want something you can't see through, look for another tool. That said, I suspect that the variable names will obscure the intent for a little while. pip install python-obfuscator Quickstart Print out obfuscated code pyobfuscate -i your_file.py Apply changes to the input file pyobfuscate -i your_file.py -r True More Detailed Documentation You can use this as a module if you want import python_obfuscator obfuscator = python_obfuscator.obfuscator () code_to_obfuscate = "print ('hello world')" No. For instance, I thought about compressing lines of code such as: However, part of me felt like this would actually make the code easier to read since we wouldnt have to map variable names. ", in Python 2 (it crashes in Python 3). Python Obfuscator with all version support, uses bytecode. Did MS-DOS have any support for multithreading? The next thing would be to write your code in a compiled language, or if you really want to go all the way, then in assembler. If we were particularly sinister, wed generate long sequences of text for each name, so its even more difficult to understand: Hell, I might even use a single random string of characters and only modify bits of it. When writing log, do you indicate the base, even when 10? Shipping the code as .pyc files will prevent your protection being foiled by a few #s, but it's hardly effective anti-piracy protection (as if there is such a technology), and at the end of the day, it shouldn't achieve anything that a decent license agreement with the company will. . So the python source is unmodified but the file extensions of the *.pyc files are different and the op codes don't match to the public python.exe interpreter. If you would like to encrypt another way, I strongly suggest you write your own encryption/obfuscation algorithm (if security is that important to you). 2 3 https://github.com/sol-prog/N-Queens-Puzzle/blob/master/nqueens.py 4 """ 5 6 This is an opinion, not a technical answer. The good point on this, is to demoralize anyone who try to decode functionallity. Yes, but not if you distribute that exact Python version with your obfuscated code. Could you tell me more please? Where on Earth is this background image in Windows from? Thx, @HenryThornton, hi, I just updated the answer with the latest code I'm using. In a nutshell, this transforms your python into C and compiles it, thus making it as well protected as any "normal" compiled distributable C program. As maximum, you can compile your sources into bytecode and then distribute only bytecode. If you have a problem of your own, feel free to ask. Python was made to be readable and shareable, not obfuscated. Likewise, Python supports various bases, so why not introduce hexadecimal, octal, and binary to the mix? Obfuscating Python Scripts with PyArmor. I am developing a piece of software in Python that will be distributed to my employer's customers. You could for example, in a modified interpreter, allow it to check for certain comments or doc strings in your source. But even this is reversible. Not sure about that wouldn't that way still be possible to decipher the code? My issue is to do it with a main.py which call several other mymodule1.py, module2.py. Connect and share knowledge within a single location that is structured and easy to search. But immature hackers are all over the place (read as curious IT staff). I've been told to use base64 but I'm not sure how. Otherwise, here are a few security related books on Amazon (ad): Once again, thanks for stopping by. We can now take that idea and begin to add code that doesnt really do anything: Here, Ive introduce a dead branch. I requested my fork be merged into the original work, but in case that never happens, here's the url to my revised version: Compile python source file to code object, Iterate code object, wrap bytecode of each code object as the following format. While this is clever and interesting, it doesn't really give an explanation to. It would start to harm you if a lot of people would find it AND those people would be paying customers instead.

Jeremy grew up in a small town where he enjoyed playing soccer and video games, practicing taekwondo, and trading Pokmon cards. B steals the money by keeping it. If you absolutely need to protect some functionality, I'd suggest going with compiled languages, like C or C++, compiling and distributing .so/.dll, and then using Python bindings to protected code. And make sure you use tools that are already natural to the Unix system i.e. The official version runs as a standalone utility, with the original intended design being that you drop a script into the root of the directory you want to obfuscate, along with a config file to define the details/options you want to employ. Instead, I want to look at various obfuscation methods. the pyc content is generated in memory after decryption - the file itself is encrypted. when you open it you can't understand anything .. ! Software development follows a variety of disciplines. Unfortunately, its sort of obvious. (c) In both (a) and (b), it should be possible to distribute the libraries as licensed binary with a Python interface. Some ideas here and here. (thx @hithwen). Cython is a low level solution. I would really recommend Nuitka over Cython. What other ways can we obfuscate Python code? Uploading your work on the Internet doesn't harm you. This is not a bad thing, it is important that several different tools exist for different usages. pyconcrete(exe) will be installed in your system path (ex: /usr/local/bin), download pyconcrete source and install by setup.py. I am looking for how to hide my Python source code. Linux script with logfile that changes names. For our implementation, I will be using the utils.py with inference function definition and will be encrypting it later. I have looked at software protection in general for my own projects and the general philosophy is that complete protection is impossible. As a result, Ill just share the options as a list: With that, I think were don for the day. (b) Use cython instead of Python. It will produce a complex encrypted and obfuscated, but fully functional script for you. After this function returns, the last instruction is to jump to # Syntax : pyarmor obfuscate --restrict=0 , # Import the inference function definition inside the utils.py file, https://pyarmor.readthedocs.io/en/latest/, https://pyarmor.readthedocs.io/en/latest/usage.html#generating-license-for-obfuscated-scripts, https://docs.python.org/3/library/smtplib.html. I've written a detailed article on how to set up Cython for a Python project, check it out: Do not rely on obfuscation. Obfuscation techniques usually involve comments/docs stripping, name mangling, trash code insertion, and so on, so even if you decompile bytecode, you get not very readable sources. I've actually seen commercial python code shipped as embedded python inside of a C library. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, py2exe just stores the .pyc byte code files in a .zip archive, so this is definitely not a solution. Some have also thought of a self modifying program to make reverse engineering expensive. And then he has to give you the tools and time so you can build what he wants. What do you mean by "import .pyd file into app.exe". See you next time! How to use the geometry proximity node as snapping tool. To be safer, you need to put some of the key functionality on your own server, so replacing it would involve substantially effort (at which point, why not just start an open-source competitor?). How to upgrade all Python packages with pip. A wee bit precaution is sensible. At the end of every article, youll find a recap full of code snippets for your own use. ", https://github.com/UM-NLP/python-obfuscation, Lets talk large language models (Ep. Simple python obfuscation for example base64 encoding can be easily cracked. Of course, there are other things you could try. Maybe you should look into using something simple like a truecrypt volume for source code storage as that seems to be a concern of yours. What is the best way to protect the Flask app python source code from been copied? You can always add value by connecting your software to a server, ie updates. I think that simply bundles the .pyc files. This is far from a perfect obfuscation scheme, anyway. "It is just a question of effort" - certainly! You could have special OP codes for such lines of code. @Daniel: Not sure. Then, on the dead branch, we return some generic value. If you want to go the extra mile, try writing a program which performs your favorite obfuscation technique. link to Why Is Adding Two Random Numbers Not the Same as Generating One in the Same Range? The obfuscated script is a normal python script. Now, we have even more code we can begin modifying. Freedom is one of the main benefits of the Python community. Rather, I thought this would be a fun exercise where we could all learn something. - software as an service (the best solution to conceal your code in my opinion) Bytecode can be decompiled. In our case, we might redefine reversed to confuse the reader into thinking it has its typical behavior: Then, we could pass whatever we wanted into it as bait. Perhaps you should use Perl then - where code looks the same before and after RSA encryption. Obfuscation techniques usually involve comments/docs stripping, name mangling, trash code insertion, and so on, so even if you decompile bytecode, you get not very readable sources. You can analyze obfuscated PHP, break the flash encryption key, etc. In particular, we indicated that the input parameter solution_path should be a string. If the license expires, network calls will be unauthenticated. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. That means better chances for you to learn about what they do and do something about it. - executable creators (or installers like PyInstaller) Just want to add my funny obfuscated "Hello world!" If the point was "copy protection", I don't think its worth the trouble for some "afternoon project". But in the end, most companies try to comply to the law (once their reputation is ruined, it's much harder to do business).

The only thing that you can hope to achieve is to add protection to a level that would cost your customer more to bypass than it would to purchase another license. Combine that with Cython and some extra crypt over modules or internet calls, and you probably got prize. Likewise, compiling and decompiling this function (i.e. What do you do after your article has been published? Choose the language that lets you develop the best product quickest, and be realistic about how valuable your novel ideas are. Not something that Python makes easy. Suddenly, its unclear what numbers were even working with. Can someone be prosecuted for something that was legal when they did it? Stopping a bunch of inexperienced hackers is easy. What's not? Unmatched records missing from spatial left join. Unfortunately, in Python, whitespace has value. The comments can be omitted if necessary. One thing we have full control over in code is naming conventions. This prints "Hello world! Well if you want to make a semi-obfuscated code you make code like this: and make a file like this (using the above code): just import "something.py" and run run(something.code) to run the code in the file. Feel free to post a new question about that. In which case, why do you even care about obfuscating? It is also one of the more secure routes to go, however, and is even recommend by some standard libraries e.g. Now if the customer sells the software, they have to change the copyright notice (which is illegal, so you can sue and will win -> simple case). I'm really surprised no one else mentioned this yet? For example: OP 234 is for source line "# Copyright I wrote this" Create a simple Latex macro which expands the format to sequence. Logical signature inside obfuscated code (e.g. Why Is Adding Two Random Numbers Not the Same as Generating One in the Same Range? This is (as has been posted previously) almost completely useless, but if you really want to, you can use alternate encoding, like say. Likewise, we also indicated that the function returns a list. That's win-win: You get changes and they can make the change themselves if they really, desperately need it even if you're unwilling to include it in the official release. Why didn't SVB ask for a loan from the Fed as the lender of last resort? Reverse engineering is doable but expensive in most situations. offset 0. SCNR. Does a purely accidental act preclude civil liability for its resulting damages? Python 3.x source code obfuscator for hiding and protecting production code. Nobody knows what is behind those network calls, so your important code will be protected. Enciphering your Python Code to avoid | by Mohammed Vaghjipurwala | Geek Culture | Medium 500 Apologies, but something went wrong on our end. Likewise, Python supports various bases, so why not introduce hexadecimal, octal, and binary to the mix? How do I check whether a file exists without exceptions? The only thing this package managed to accomplish is to fool the 'obfuscator' that the code is obfuscated. Obfuscate a Python Program With Pyarmor Code obfuscation is the deliberate process of creating source or machine code that is difficult for humans to understand but still executable by a computer. Now we will encrypt it, by running the following 2 commands. @mlvljr FWIW, IMHO compiling to binaries is a nice tradeoff between selling all your secrets and trying to protect against NSA-class reverse engineering. Or validate the licence not only on startup but in several other places. So if you have 30 lines of code you'll probably want to encrypt it doing something like this: You'd then need to write a second script that does the compile() and eval() which would probably include the encoded script as a string literal encased in triple quotes. Another way to make code unintelligible is to find hardcoded strings like utf8 in our example and add an unnecessary layer of abstraction to them: Here, weve constructed the string utf8 from its ordinal values. Prints erroneous messages to the extension, it is important that several different tools exist for different usages that will!
