    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() Related Links Cryptography API: Next Generation - Main Page Cryptography API: Next Generation - Reference Cryptography API: Next Generation - Primitives Cryptography API: Next Generation - Cryptographic Algorithm Providers
  2. I'm attempting to decrypt a file previously encrypted with the encrypt file function; then read that file into an array and display it. When I read the file into an array it still shows me garbled text if any at all. What am I doing wrong here? $serial = "stepping through array var" $FileHandle = "C:\XXX\Serial.txt" If FileExists($FileHandle) Then $Password = "password" _Crypt_DecryptFile($FileHandle, $FileHandle, $Password, $CALG_RC4) $FileArray = 0 ;initilze computer list array _FileReadToArray($FileHandle, $FileArray) _ArrayDisplay($FileArray) ;why is this showing encrpyted data?!?! FileOpen($FileHandle) FileWriteLine($FileHandle, $serial) FileClose($FileHandle) Else FileOpen($FileHandle) FileWriteLine($FileHandle, $serial) FileClose($FileHandle) EndIf $Password = "password" _Crypt_EncryptFile( $FileHandle, $FileHandle, $Password, $CALG_RC4) Next Any help is greatly appreciated!
