    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).
  2. Hi guys. I try to choose an algorithm to compress some string data in-memory, without file medium to store in sqlite as blob. I plan to store about 100k blobs each 80k symbols (uncompressed). First opinion was LZMA udf by Ward, but udf file doesn't exist. Then i tried to use BZIP2 dll in DllCall, but it simply doesn't work and throws @error = 1. Here is an example: What should I do with this error? Where am I wrong? Thanks.
  3. I have been searching the forum - which may have been impacted by the recent upgrade - or maybe I am just not searching correctly . Either way, I have seen references to zlib.au3 but I can't seem to find the UDF anywhere. Would anyone happen to know its location?
  4. BinaryToAu3Kompressor v1.0.5.4 It's now possible to see the best compression ratio using LZMA, LZNT and Base64 compressions with differents combinations. Nothing too complicate, you drag'n drop a file on the picture and script Test all compression types and return the ratios. ( Test duration depends of file size, slowest compression is LZNT, but all decompressions are fast ) Free to you after, to choose the compression(s) you want... Yes, LZMA needs a dll ( embedded & compressed in script ) but brings a powerfull compression. It opens scite with your file compressed to an au3 script with or without decompression function as you want. Hold Left Shift key when clicking button for just copy script to clipboard. Use the 3 compressions at a time works but doesn't give a good ratio, that's why i don't display it. Usefull for little files you want include in your scripts ! No externals files needed, they are already in script. Previous downloads : 1103 Source and Executable BinaryToAu3Kompressor will be added to the next version of >SciTEHopper Thanks to Ward for his >Base64.au3 and LZMA.au3, and trancexx for his >LZNT functions and his >Base64Decode function.
  5. I'm trying to activate the compression feature in AVIFIL32.DLL using monoceres' My problem is that the return value of the call $aRet = DllCall($Avi32_Dll, "int", "AVIMakeCompressedStream", "ptr*", 0, "ptr", $pstream, "ptr", DllStructGetPtr($aco), "ptr*", 0)is always 0x80040154 which is an error. You can check out at MSDN how the AVI functions have to be called. Further I tried understand the VB5 code how the code is activating the compression. Here the modified AVIWriter code which will take for 5 seconds at 15 fps screenshots from active window and put it to the avi container: #AutoIt3Wrapper_UseX64=n #include <WinAPI.au3> #region AVIWriter UDF ;Global Const $mmioFOURCC_M_S_V_C = _Create_mmioFOURCC("MSVC") ;1129730893 Global Const $BITMAPFILEHEADER = "align 2;char magic[2];int size;short res1;short res2;ptr offset;" Global Const $BITMAPINFOHEADER = "dword biSize;long biWidth;long biHeight;short biPlanes;short biBitCount;" & _ "dword biCompression;dword biSizeImage;long biXPelsPerMeter;long biYPelsPerMeter;dword biClrUsed;dword biClrImportant;" Global Const $OF_CREATE = 0x00001000 Global Const $AVIIF_KEYFRAME = 0x00000010 Global Const $ICMF_CHOOSE_KEYFRAME = 1, $ICMF_CHOOSE_DATARATE = 2 Global Const $AVIERR_UNSUPPORTED = 0x80044065 Global Const $AVIERR_MEMORY = 0x80044067 Global Const $AVIERR_NOCOMPRESSOR = 0x80044071 Global Const $AVIERR_CANTCOMPRESS = 0x80044075 Global Const $AVIERR_ERROR = 0x800440C7 Global Const $AVIERR_OK = 0 Global $Avi32_Dll ;http://msdn.microsoft.com/en-us/library/ms899423.aspx Global Const $AVISTREAMINFO = "dword fccType;dword fccHandler;dword dwFlags;dword dwCaps;short wPriority;short wLanguage;dword dwScale;" & _ "dword dwRate;dword dwStart;dword dwLength;dword dwInitialFrames;dword dwSuggestedBufferSize;dword dwQuality;" & _ "dword dwSampleSize;int rleft;int rtop;int rright;int rbottom;dword dwEditCount;dword dwFormatChangeCount;wchar[64];" ;http://msdn.microsoft.com/en-us/library/dd756791(v=VS.85).aspx Global Const $AVICOMPRESSOPTIONS = "DWORD fccType;DWORD fccHandler;DWORD dwKeyFrameEvery;DWORD dwQuality;DWORD dwBytesPerSecond;" & _ "DWORD dwFlags;PTR lpFormat;DWORD cbFormat;PTR lpParms;DWORD cbParms;DWORD dwInterleaveEvery;" Func _Create_mmioFOURCC($FOURCC) ;http://www.fourcc.org/codecs.php If StringLen($FOURCC) <> 4 Then Return SetError(1, 0, 0) Local $aFOURCC = StringSplit($FOURCC, "", 2) Return BitOR(Asc($aFOURCC[0]), BitShift(Asc($aFOURCC[1]), -8), BitShift(Asc($aFOURCC[2]), -16), BitShift(Asc($aFOURCC[3]), -24)) EndFunc ;==>_Create_mmioFOURCC Func _DecodeFOURCC($iFOURCC) If Not IsInt($iFOURCC) Then Return SetError(1, 0, 0) Return Chr(BitAND($iFOURCC, 0xFF)) & Chr(BitShift(BitAND(0x0000FF00, $iFOURCC), 8)) & Chr(BitShift(BitAND(0x00FF0000, $iFOURCC), 16)) & Chr(BitShift($iFOURCC, 24)) EndFunc ;==>_DecodeFOURCC ; monoceres, Prog@ndy Func _CreateAvi($sFilename, $FrameRate, $Width, $Height, $BitCount = 24, $mmioFOURCC = "MSVC") Local $RetArr[5] ; avi file handle, stream handle, bitmap count, BitmapInfoheader, Stride Local $aRet, $pfile, $asi, $aco, $pstream, $psCompressed $aRet = DllCall($Avi32_Dll, "int", "AVIFileOpenW", "ptr*", 0, "wstr", $sFilename, "uint", $OF_CREATE, "ptr", 0) $pfile = $aRet[1] Local $stride = BitAND(($Width * ($BitCount / 8) + 3), BitNOT(3)) Local $bi = DllStructCreate($BITMAPINFOHEADER) DllStructSetData($bi, "biSize", DllStructGetSize($bi)) DllStructSetData($bi, "biWidth", $Width) DllStructSetData($bi, "biHeight", $Height) DllStructSetData($bi, "biPlanes", 1) DllStructSetData($bi, "biBitCount", $BitCount) DllStructSetData($bi, "biSizeImage", $stride * $Height) $asi = DllStructCreate($AVISTREAMINFO) DllStructSetData($asi, "fccType", _Create_mmioFOURCC("vids")) DllStructSetData($asi, "fccHandler", 0) ;_Create_mmioFOURCC($mmioFOURCC)) DllStructSetData($asi, "dwScale", 1) DllStructSetData($asi, "dwRate", $FrameRate) ;~ DllStructSetData($asi, "dwQuality", $Quality) ;Quality is represented as a number between 0 and 10,000.
