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).
I'm trying to read a binary file to an array but couln't get it to work.
Also I coul not find any help in the forum around this subject whish was helpfull.
Is there any way it could be done?
I tried a lot of ways but maybe somebody know's the right way?
#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7 #include <File.au3> #include <Array.au3> #include <AutoItConstants.au3> Local $in=FileOpen("TEST_labels.idx1-ubyte",16) ; 16+0=Read binary Local $data = FileRead($in) Local $FileArray = BinaryToString($data,4) ;~ $FileArray = StringSplit($BinarydData, @CRLF, 1+2) ;~ Local $FileArray = StringRegExp($BinarydData, "[^\r\n]+", 3) FileClose($in) _ArrayDisplay($FileArray,"$FileArray","",32) MsgBox($MB_SYSTEMMODAL, "", "$FileArray = " & $FileArray )
A couple week ago i've started learning API Interface for different websites. In this fact sometimes you have to encode your "photo" or "document.body" to send request.
Functions to encode and decode Base64 was already created by others. Unfortunately i have troubles with running it on Windows R 2008, also speed was terrible.
I try to find alternative way to code data.
I've read about Microsoft "XMLDOM" and created a one simple function to Encode / Decode data to base64binary, base64url
Thanks for Ghads on Wordpress i coverted a part of his lines from VBscript to AutoIT
;============================================================================================================================== ; Function: base64($vCode [, $bEncode = True [, $bUrl = False]]) ; ; Description: Decode or Encode $vData using Microsoft.XMLDOM to Base64Binary or Base64Url. ; IMPORTANT! Encoded base64url is without @LF after 72 lines. Some websites may require this. ; ; Parameter(s): $vData - string or integer | Data to encode or decode. ; $bEncode - boolean | True - encode, False - decode. ; $bUrl - boolean | True - output is will decoded or encoded using base64url shema. ; ; Return Value(s): On Success - Returns output data ; On Failure - Returns 1 - Failed to create object. ; ; Author (s): (Ghads on Wordpress.com), Ascer ;=============================================================================================================================== Func base64($vCode, $bEncode = True, $bUrl = False) Local $oDM = ObjCreate("Microsoft.XMLDOM") If Not IsObj($oDM) Then Return SetError(1, 0, 1) Local $oEL = $oDM.createElement("Tmp") $oEL.DataType = "bin.base64" If $bEncode then $oEL.NodeTypedValue = Binary($vCode) If Not $bUrl Then Return $oEL.Text Return StringReplace(StringReplace(StringReplace($oEL.Text, "+", "-"),"/", "_"), @LF, "") Else If $bUrl Then $vCode = StringReplace(StringReplace($vCode, "-", "+"), "_", "/") $oEL.Text = $vCode Return $oEL.NodeTypedValue EndIf EndFunc ;==>base64
I'm searching a way to do xor and shift and if possible also other operations. Thanks in advance for the replies.
I'm too stupid to see my mistake:
To investigate the internal "dictionary" of TIFF files I'd like to read in the files in binary mode and to check, if there are more than one pages "in" this TIFF.
Notepad++, "View as Hex" is presenting the first bytes as "49 49 2a 20 08 20 20 20 12" for the TIF attached to this posting
The "TIFF Header Format" is easy:
Offset 00h, 2 Byte = Byte Order, "II"=intel, "MM"=motorola. (I = 0x49)
Offset 02h, 2 Byte = Version Nr.
Offset 04h, 4 Byte = pointer to first IFD entry
Description of TIFF header: https://www.awaresystems.be/imaging/tiff/faq.html#q3
Howto read and analyse the binary content correctly? This is my messy, not operational code:
$sampleTiff="H:\daten\tif\11\11\111111.TIF" $h=FileOpen($sampleTiff,16) $content=FileRead($h) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $content = ' & $content & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console FileClose($h) $type=VarGetType($content) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $type = ' & $type & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $ToString=BinaryToString($content) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $ToString = ' & $ToString & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console ConsoleWrite(@CRLF & @CRLF) $content=StringTrimLeft($content,2) ; cut off the leading "0x" ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $content = ' & $content & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console for $i = 1 to 8 step 8 $next=StringMid($content,$i,2) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $next = ' & $next & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $Chr=BinaryToString($next) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $Chr = ' & $Chr & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console ConsoleWrite(@CRLF & "---" & @CRLF) Next Regards, Rudi.
