    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. Here's Base91 and Base128 functions I ported from code I found on the net. Quick search of the forum did not pull up anything so don't think these have been posted before. Both just for fun. The base128 is pretty straight forward as its pretty much the same concept as base64 only using 7bits instead of 6, but I thought the base91 was real interesting and Im actually still trying to wrap my head around the algorithm. The functions Ive posted are shortened/combined a bit so if your gonna try and learn the flow I would break it back down to one operation per line. Let me know if you find a string it does not work with. I mainly wanted them for embedding dlls in scripts and the the results are below for a dll that I tested. Have fun!

  3. Hi, is there a function or a UDF for parsing a hotkey definition string like "^a" or "+!{F1}" ? I´d like to create a settings GUI where users are able to define their custom hotkeys for a specific function and then save it to an ini. Of course, at the next start of the program, these settings have to read and not only the HotkeySet() command needs to be fed with it but also the settings GUI. As I do not want to present the user just the hotkey string but a rather user-friendly display (like checkboxes for the separate modifier keys and a drop down list of supported trigger keys), I need to fiddle on the saved string. I would envision a function that takes a hotkey string and returns for example an array like this: [isCtrl][isAlt][isShift][isWin][triggerKey][isTriggerVirtual]. And of course, there needs to be a function decoding the array back to the respective string representation. Thanks for your hints!
  4. Hello! I've been lurking around for a loooong time... and I decided to finally share a little. I do a lot of internet stuff, mostly machine to machine for work (instrumentation) so I have quite a few "RFC" scripts. Disclaimer these work for me... but I sometime use... "shortcuts" based on my particular requirement. An example, the Base64 encoding snippet might not be too good for binary data. I pad the original data with spaces to avoid the "==" padding of base64. So... first is the base64 encoding snippet. It is not in a function, it was in a sequential program, used only once! It encode $Graph to $SMTPMessage: ; Create the base64 encoding table Dim $Base64EncodingTable[0] For $Cpt = Asc("A") to Asc("Z") _ArrayAdd($Base64EncodingTable, Chr($Cpt)) Next For $Cpt = Asc("a") to Asc("z") _ArrayAdd($Base64EncodingTable, Chr($Cpt)) Next For $Cpt = Asc("0") to Asc("9") _ArrayAdd($Base64EncodingTable, Chr($Cpt)) Next _ArrayAdd($Base64EncodingTable, "+") _ArrayAdd($Base64EncodingTable, "/") ; Pad the SVG Graph to attach with space(s). Lazy way to avoid base64 == pading While Mod(StringLen($Graph), 3) <> 0 $Graph &= " " WEnd ; Start from the first character $Cpt = 1 Do ; Extract the 3 characters to encode $Char1 = Asc(StringMid($Graph, $Cpt, 1)) $Char2 = Asc(StringMid($Graph, $Cpt+1, 1)) $Char3 = Asc(StringMid($Graph, $Cpt+2, 1)) ; Encode them to 4 characters $SMTPMessage &= $Base64EncodingTable[BitShift(BitAND($Char1, 252), 2)] $SMTPMessage &= $Base64EncodingTable[BitShift(BitAND($Char1, 3), -4) + BitShift(BitAND($Char2, 240), 4)] $SMTPMessage &= $Base64EncodingTable[BitShift(BitAND($Char2, 15), -2) + BitShift(BitAND($Char3, 192), 6)] $SMTPMessage &= $Base64EncodingTable[BitAND($Char3, 63)] ; Increment the counter, and if required, add a @CRLF to split in multiples lines $Cpt += 3 If Mod($Cpt, 57) = 1 Then $SMTPMessage &= @CRLF ; Do this until all the graph has been encoded Until $Cpt >= StringLen($Graph) Second... I just finished this one and was allready thinking about sharing it... so it's been encapsulated into function a bit more. I use it to decode email subjects in a system where you can update something by email. I separated the Base64Decode function so it can be grabbed more easily. Please note that it return an hex string so you would still need to convert it if it's a string with BinaryToString or whatever suit your needs.

I may update it into a better format for you, like a standalone telnet program with GUI. It is my telnet options negociations loops.

If it says "Do", I reply "Wont"... unless it's the terminal type subnegociation, in which case I reply xterm! $Data for now needs to be Global.

  6. I would like to programmatically check to see if a given tracker has information on the torrent I specify. This requires that the SHA-1 Info Hash of a torrent be encoded to make valid requests. I read from: http://nakkaya.com/2009/12/03/bittorrent-tracker-protocol/ If you don't pay attention to the spec and send this directly to tracker you will get an error this should be in URL Encoded form. Padding every two chars with % sign also doesn't work, been there done that don't waste your time. Any hex in the hash that corresponds to a unreserved character should be replaced, a-z A-Z 0-9 -_.~ Partition the hex in to chunks of two and check if the hex corresponds to any of these values, if they do replace them with the unreserved char. So that a hash such as, 123456789abcdef123456789abcdef123456789a becomes, %124Vx%9a%bc%de%f1%23Eg%89%ab%cd%ef%124Vx%9a notice that hex 34 became 4 which is what it is in ASCII. You can test the correctness of your hashes using the tracker url but don't request from announce request from file, http://some.tracker.com/file?info_hash=hash If you get a torrent back that means you have the correct hash. I have tried the above and failed. Here's my code: $testStr = "123456789abcdef123456789abcdef123456789a" ConsoleWrite(_EncodeHash($testStr) & @CRLF) Func _EncodeHash($sString) If (Not IsString($sString)) Or $sString = "" Then Return SetError(1, 0, 0) Local $aArray = StringRegExp($sString, "(?s).{1," & 2 & "}", 3), $sEncodedHash For $i = 0 To UBound($aArray) -1 If StringInStr($sString, Chr(Dec($aArray[$i]))) Then $sEncodedHash &= Chr(Dec($aArray[$i])) Else $sEncodedHash &= "%" & $aArray[$i] EndIf Next Return $sEncodedHash EndFuncIf you follow the first link in my post there is an example but I'm unfamiliar with the language being used. Thanks for any help.
