Encryption / Decryption / Hashing
Cryptography API: Next Generation (CNG) is Microsoft's long-term replacement for their CryptoAPI. CNG is designed to be extensible at many levels and cryptography agnostic in behavior. Although the Crypt.au3 UDF that is installed with AutoIt3 still works perfectly, the advapi32.dll functions that it uses have been deprecated. This UDF was created to offer a replacement for the deprecated functions. According to Microsoft, deprecated functions may be removed in future release. Therefore, this UDF will be available when/if that happens.
This UDF implements some of Microsoft's Cryptography API: Next Generation (CNG) Win32 API functions. In its initial release, it implements functions to encrypt text & files, decrypt text and files, generate hashes, and the Password-Based Key Derivation Function 2 (PBKDF2) function. The UDF can implement any of the encryption/decryption algorithms or hashing algorithms that are installed on the PC in which it is running. Most, if not all, of the values that you would commonly use to specify that desired algorithms, key bit lengths, and other magic number type values, are already defined as constants or enums in the UDF file.
To flatten the learning curve, there is an example file that shows examples of all of the major functionality. This example file is not created to be an exhaustive set of how to implement each feature and parameter. It is designed to give you a template or guide to help you hit the ground running in terms of using the functions. I have tried to fully document the headers of all of the functions as well as the code within the functions themselves.
The UDF currently has all of the same functionality as the Crypt.au3 except for the random number generation function. I left that out of the initial version because the functionality already exists in the Crypt.au3 UDF as well as the Random() function in AutoIt3 itself.

The CodeScannerCrypterBundle (ca. 2.5 MB) contains the following UDFs and utilities:
CodeScanner: analyse AutoIt script structure and content, identify potential issues, generate MCF data files CodeCrypter: front-end GUI for the MCF library, for script encryption (without storing the decryption key(s) in the script!) MetaCodeFile UDF (MCF library): for analysis and user-defined alterations of AutoIt script structure and content MCFinclude.au3: #include this UDF in any AutoIt script that you wish CodeCrypter to process AES.au3, by Ward; machine code UDF for AES encryption (32-bit, patched version) CryptoNG, by TheXman; encryption UDF using Bcrypt dll calls (32/64-bit; various algorithms) StoreCCprofile.au3/readCSdatadump.au3/helloworld.au3: auxiliary utilities and example script HowToCodeCrypt.pdf: a simple guide in five steps CodeCrypterFAQ.pdf: questions and answers, partly based upon exchanges in the CodeCrypter thread. Please follow the links for additional information.
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.
A brief Tutorial is here: MetaCode Tutorial.pdf
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).
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):
Latest version: 3.1, (27 Feb 2020): please follow this link.
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:
a simple HowTo Guide: HowToCodeCrypt.pdf an updated and extended Q & A pdf (FAQ, also included in the bundle) to help you get started:CodeCrypterFAQ.pdf For additional explanations/examples in response to specific questions by forum members (how it works, what it can/cannot do), see elsewhere in this thread, notably:
Simple analogy of how it works: post #53, second part General Explanation and HowTo: post #9, 51, 75, 185/187, 196, 207, 270, 280 (this gets a bit repetitive) BackTranslation: post #179 Obfuscation: post #36 (general), 49 (selective obfuscation) Specific features and fixes: post #3 (security), 84 (redefining the expected runtime response), 169 (Curl Enum fix), 185/187 (using license keys), 194 (replacing Ward's AES UDF with different encryption/decryption calls), 251 (AV detection issue), 262 (extract key contents to USB on different target machine prior to encryption) Limitations: post #26 (@error/@extended), 149 (FileInstall), 191 (AES.au3 on x64) Not recommended: post #46/249 (static encryption), 102 (programme logic error), 237 (parsing password via cmdline)
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.
Encryption currently relies on Ward's excellent AES UDF and TheXman's sophisticated CryptoNG bundle. You can replace these with any other algorithm you like (but this is not trivial to do: edit MCFinclude.au3 UDF _MCFCC(), and MCF.au3 UDF _EncryptEntry(), see post #194 in this thread). AES by Ward, and CryptoNG by TheXman are also included in the bundle (with many thanks to Ward and TheXman for graciously allowing me to republish their outstanding work).
Going to lie down now...
