The CodeScannerCrypterBundle (ca. 2.9 MB unzipped) 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 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. MetaCodeTutorial.pdf: the MCF engine explained; useful for encryption, GUI translation, code translation, and much more... Please follow the links for additional information.
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. As of v1.4.0, there is also a Help file that includes all of the functions, with examples.

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).
I would like to know if it is possible to implement an autoit script with GOST algorithm. I noticed that there are seven different algorithms in the standard UDF, but I urgently need a command line crypter with GOST algorithm. I just lack the algorithm part. Is it possible to adapt GPLib in the autoit script?
I had created login form and this form first goes to de-crypting file that encrypted then read the saved credentials by de-cryptied file, but doesn't work properly!
I want just read encrypted data without saving de-crypted file, just read!
