CryptoNG UDF - Cryptography API: Next Generation
By TheXman
Encryption / Decryption / Hashing
Purpose
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.
Description
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 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.
Current UDF Functions
_CryptoNG_CreateRSAKeyPair($iKeyBitLength, $sPublicKeyPath, $sPrivateKeyPath, $sProvider = "Microsoft Primitive Provider") _CryptoNG_DecryptData($sAlgorithmId, $xData, $vEncryptionKey, $sProvider = "Microsoft Primitve Provider") _CryptoNG_DecryptFile($sAlgorithmId, $sInputFile, $sOutputFile, $vEncryptionKey, $sProvider = "Microsoft Primitve Provider") _CryptoNG_EncryptData($sAlgorithmId, $sText, $vEncryptionKey, $sProvider = "Microsoft Primitve Provider") _CryptoNG_EncryptFile($sAlgorithmId, $sInputFile, $sOutputFile, $vEncryptionKe, $sProvider = "Microsoft Primitve Provider") _CryptoNG_EnumAlgorithms($iAlgorithmOperations) _CryptoNG_EnumRegisteredProviders() _CryptoNG_HashData($sAlgorithmId, $vData, $bHMAC = False, $vHMACSecret = "", $sProvider = "Microsoft Primitve Provider") _CryptoNG_HashFile($sAlgorithmId, $sFilePath, $bHMAC = False, $vHMACSecret = "", $sProvider = "Microsoft Primitve Provider") _CryptoNG_LastErrorMessage() _CryptoNG_PBKDF2($sPassword, $vSalt, $iIterations, $iDKeyBitLength, $sHashAlgorithmId = $CNG_BCRYPT_SHA1_ALGORITHM, $sProvider = "Microsoft Primitve Provider") _CryptoNG_Version()

Ward's AutoIt Machine Code Algorithm Collection

AutoIt Machine Code Algorithm Collection
By Ward, November 11, 2010 in AutoIt Example Scripts
Posted November 11, 2010 (edited) I have already published a lot of AutoIt UDF about algorithm, but all of them only support 32 bits or so called X86 system. Recently I got a computer with Windows 7 64 bits, so I finally added X64 support to most of my old projects. Besides, I also added some new. For example, some compression algorithm and SHA3 Candidates.
Following are the algorithms list:
Checksum CRC16 CRC32 ADLER32 Compression FastLZ LZF LZMA LZMAT MiniLZO QuickLZ Encode Base64 ARC4 XXTEA DES AES Hash Checksums (CRC16/CRC32/ADLER32) MD2 MD4 MD5 SHA1 SHA2 (SHA224/256/384/512) SHA3 Candidates BLAKE BMW (Blue Midnight Wish) CUBEHASH ECHO SHABAL SKEIN Some points to mention:
All of the subroutines have one or more examples to demonstrate the usage. Since the function and usage of subroutine are easy to understand. A complete subroutines and parameters list are unavailability now. Sorry for my lazy. All of the subroutines here invoked by Lazycat's method (through CallWindowProc API). My MemoryDLL UDF is not necessary this time. Although MemoryFuncCall (part of MemoryDLL) is still good, but inevitably, it is slower than CallWindowProc. Some subroutines have the same name with my old machine code version UDF. But for some reason, I rearrange the position of the parameters. Please not mix up. If you notice, yes, checksums are duplicated. But they receive different parameters. One is the old style, and another use the same interface as other hashes. Choose what you like, but don't use them in the same time. Some algorithm already supported by the standard UDF "Encryption.au3". But I still provide them, because some system lack of the full support of Windows Crypt Library. If you are looking for only one hash algorithm, for example, used in encryption, I suggested "SHABAL_TINY.au3". Although it is a bit slower then SHABAL, but it is smaller, and it supports different size of output (from 32 to 512 bits).237 downloads

(Un)Serialize() in AutoIt (PHP compatible)
By Jefrey
UDF for serializing and unserializing data.
Serializing is converting any data to an easily storable format (you can convert an array to a string to save in a database, then convert it back to array).

Hashing Library
By FuryCell
WARNING:The code for these UDFs have not been updated in quite some time , and is now incompatible with new versions of both autoit and MD5 deep. As such I reccomed using one of the many other hashing UDFS and/or plug ins available on the forum.
This library lets you generate MD5,SHA1,SHA256,Tiger, and WhirlPool hashes for files and strings.
It contains two functions, _FileHash(), and _StringHash().
To use these UDFs you need the *Deep set of command line utilities which can be downloaded here.
Enjoy.
