CodeCrypter enables you to encrypt scripts without placing the key inside the script.
This is because this key is extracted from the user environment at runtime by, for example:
password user query any macro (e.g., @username) any AutoIt function call any UDF call some permanent environment variable on a specific machine (and not created by your script) a server response a device response anything else you can think of, as long as it's not stored in the script any combination of the above You need several scripts to get this to work, and they are scattered over several threads, so here's a single bundle that contains them all (including a patched version of Ward's AES.au3; with many thanks to Ward for allowing me to include this script here):
Note: if you experience issues under Win8/8.1 (as some users have reported), please upgrade to Win10 (or use Win7) if you can; as far as I can tell, the scripts in the bundle all work under Win7 & Win10 (and XP). Moreover, I have no access to a Win8 box, so these issues will not be fixed, at least not by yours truly.
How the bits and pieces fit together:
CodeCrypter is a front-end for the MCF UDF library (you need version 1.3 or later). Its thread is here:
'?do=embed' frameborder='0' data-embedContent>>
The MCF package (also contained in the CodeScannerCrypter bundle) contains MCF.au3 (the library itself) plus a little include file called MCFinclude.au3. The latter you have to include in any script you wish to encrypt. Any code preceding it will not be encrypted, any code following it will be encrypted. You define the dynamic key inside MCFinclude.au3, in the UDF: _MCFCC_Init().
From the same post you can download an MCF Tutorial which I heartily recommend, because encrypting a script requires a number of steps in the right order, namely:
In MCFinclude.au3, define and/or choose your dynamic key(s) (skip this step = use default setting) include MCFinclude.au3 in your target script Run CodeScanner (version 2.3+) on your target script, with setting WriteMetaCode=True (see '?do=embed' frameborder='0' data-embedContent>>), then close CodeScanner. Start CodeCrypter press the Source button to load your target file enable Write MCF0 (tick the first option in Main Settings) Enable "Encrypt" (last option in the Main Settings) Go to the Tab Encrypt and set up the encryption the way you want (skip this = use default settings) Return to Main Tab and press "Run" if all goes well, a new script called MCF0test.au3 is created in the same directory as your target. It has no includes and no redundant parts. Please check that it works as normal. (see Remarks if not) It all sounds far more complicated than it is, really.
Not convinced? Check out this updated and extended Q & A pdf (FAQ, also included in the bundle) to help you get started:
BackTranslation is a test to check that the MetaCode translation worked. Skip it at your peril. It also turns your multi-include composite script into a single portable file without redundant parts (you can opt to leave the redundant parts in, if you want).
CodeCrypter can also obfuscate (vars and UDF names) and replace strings, variable names and UDF names with anything else you provide, for example, for language translation). After CodeScanner separates your target's structure from its contents, CodeCrypter (actually MCF, under the hood) can change any part, and then generate a new script from whichever pieces you define. See the MCF Tutorial for more explanation and examples.
You need the following additional scripts to get anything to work (now all included in the bundle):
CodeScanner.au3 version 2.9+ (in the CodeScanner zip in the CodeScanner thread, link above) readCSdatadump.au3 (version 1.1+, in the CodeScanner zip) MCF.au3 (version 1.3+, in the MCF zip in the MCF thread, link above) MCFinclude.au3 (version 1.1+, in the MCF zip) AES.au3, by Ward (now also included in bundle, thanks to Ward), see '?do=embed' frameborder='0' data-embedContent>> As you can see, encryption currently relies on Ward excellent AES UDF, but you can replace this with any other algorithm you like; just edit MCFinclude.au3 UDF _MCFCC(), and MCF.au3 UDF _EncryptEntry().
Going to lie down now...
Hello all, I would like to present my proof of concept work to the autoit forum and community. (I saw this as a concept in a few sci-fi shows and thought I would bring it into real life)
What is it?: DARTIS (Dimensions And Relative Time Information System)© is a 4 dimensional holographic encryption algorithm which uses the current timestamp(measured down to femto seconds) to encrypt data under several layers of calculations. One large keyfile is used and multiple keys are extracted from it, and overlaid on each other to create 1,000,000,000,000,000 unique keys per second. Special thanks to the creator of the matrix maths udf (if this is you please let me know and I will put your name here.) Also special thanks to trancexx for her LZNT compression code.
Please see the following link for the full set of functions and an example debugging application, which shows usage of all the functions.
https://pdglobal.net/?pid=SIM#SIM (DARTIS is packed with SIM)
DARTIS is an encryption scheme that extracts a timestamp from the current system time, then splits it up into an array of strings each 4 digits long.
Then those strings are plugged into the 16mb keyfile blueprint, where each 4 digit value represents a 2D array.
Then each 2D array is layered on top of the one that came before it, compressing the data underneath several layers of encryption.
It's 4D because the key is derived from the system time(so the same key will never be used twice)
And it's holographic because the data is buried underneath several layers of data.
The full 16mb keyfile blueprint is required to re-extract the data that has been injected into the holographic keyfile blueprint. (as the values all have to be the same AND be in the same order)
The only downside to this encryption scheme is that the only safe way to distribute keys is by snail mail or in person. (because if you transmit it via the internet, you're limiting the security of your keyfile blueprint to whatever lesser encryption algorithm you;re using to transmit the keyfile blueprint)
Hope I explained it in a way that's easy to understand! If you have any further questions about it feel free to ask! (and/or look around the DARTIS.au3 file to see how this is done, and run DEBUG.au3 to see under the hood)
MetaCode offers a way to:
separate a script's structure from its content remove all redundant definitions (globals and UDFs) change any content (and some structure) combine (new) structure and (new) content into a new script The most useful applications implemented so far are:
Fast language translation (not just text strings, also variable names and UDF names) Obfuscation (vars and/or UDFs) Script Encryption (conditionals, calls, and macros) Encryption is powerful because the key is not stored anywhere; you can define it to be a user password, macro, environment spec/variable, server response, something you define yourself, or a combination thereof; anything goes, as long as it's not a fixed string or fixed value. More info in the CodeCrypter thread: ?do=embed' frameborder='0' data-embedContent>'?do=embed' frameborder='0' data-embedContent>>?do=embed' frameborder='0' data-embedContent>
But MetaCode has more potential than that; it allows you to tinker with any type of content separately, then rebuild a new version. So for example, you can have a single script structure and numerous different language modules you just plug in to create a new version in a different language.
The MCF library itself can be found in the CodeScannerCrypter bundle:
And a little example how to use it for translating your GUI into a different language:
UI_Translator.7z (new version that should work with the new version of Google Translate, see post #13 below)
MCF.au3 is just the library plus the MCFinclude.au3 file you need to include in any script you wish to encrypt.
There is no GUI here. However, I did write a separate front-end for it called CodeCrypter, which you can find here:
?do=embed' frameborder='0' data-embedContent>'?do=embed' frameborder='0' data-embedContent>>?do=embed' frameborder='0' data-embedContent>
MCF uses output generated by my CodeScanner version 2.8+, which you can find here:
'?do=embed' frameborder='0' data-embedContent>>
CodeScanner also depends on MCF.au3 now, as it can now call a few of its functions.
I should also mention Ward's excellent AES.au3 UDFs used for the encryption and decryption calls, which is now included in the CodeScannerCrypter bundle (thanks to Ward for allowing to include it). You can find the original (unpatched) version here:
'?do=embed' frameborder='0' data-embedContent>>
Note: you can replace the encryption/decryption calls with whatever algorithm you like (hint: the native <Crypt.au3> library is too slow for most purposes, better stick to machine code routines)
So just to be clear:
CodeScanner (v2.8+) needs MCF (earlier versions won't work!) CodeCrypter needs MCF (plus anything that MCF needs) MCF itself needs MCFinclude (part of MCF zip) MCF also needs readCSdatadump (part of the CodeScanner package, you need the latest version packaged with CodeScanner v2.8; earlier versions won't work!) both MCF and MCFinclude currently rely on AES.au3 by Ward So you basically need to download the whole bundle for any of it to work.
If you have any questions, please start by reading the MCF Tutorial and the CodeCrypter FAQ (you can download the latter separately from the CodeCrypter thread).
Next, read the extensive Remarks sections in MCF.au3, MCFinclude.au3, and CodeCrypter.au3
If still no joy, then please post. However, I'm not online that often, and logged in to the forum even less, so response may take a while).
Hello friends! I have been working on an encryption algorithm in autoit as a proof of concept for some time now. Basically the algorithm uses a progressive recursion to encode data inside a matrix using a key that changes according to the date-time of the system, which is extracted from a larger key array. Recently after a drive failure, I lost the source and had to start from scratch, now I can't quite get it working the way it was before, and I can't see what I'm doing wrong, if anyone who understands matrix math or encryption could help I would much appreciate it. The problem is that the values returned by the decryption (extraction) process are way too big.
I have figured out the solution to my problem, it was a typo, please disregard this thread.
I will post my project into example scripts when it's ready.
i hope i am in the right place for this question as it is in regards to zip.au3.
I have some encrypted files on my harddrive which zip.au3 can't open. This is perfectly fine. The Problem is that it crashes my program as soon as it tries to access the file.
Is there a way to detect if the file is encrypted BEFORE autoit tries to open it? I am using _zip_unzipall to unzip the file, i also tried _zip_count with the same result. My files are encrypted with SafeGuard Lan Crypt.
