Base64 Machine Code Functions + Source

12 posts in this topic

#1 ·  Posted (edited)

Here's 2 base64 machine code functions I wrote that came out pretty good. Both encode and decode are x64 capable. Comparing times for encoding/decoding the autoit.exe with Microsofts functions, I got them beat by a good percentage for both x84/x64 decode functions. I'm pretty sure thats due to my reverse index idea. It ended up working very well.  I beat there x86 encode by a little bit, but they got me beat by just a hair for x64 encode. The attachment includes example that has the time tests I did, plus has the assembly source. Let me know if you have any issues or see something that is scewing my results somehow. Thanks!

Beege,

Thanks for your work on this! I am trying to sign a request to amazon MWS servers and I need to convert the signed HMAC string to Base64.  Amazon provides a scratchpad site that I am using to test my algorithm to make sure it is hashing properly and converting to Base64 as well.  So far I am doing fine at hashing and encrypting the request strings, but when I use your function to convert to Base64 it does not consistently give me the same output.

For example when the hash is:

e900fe550acdf319cf68b924f5625323ab89b1954753b2e9e429775e774511f4

then Amazon shows the Base64 to be:

6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfQ=

After running your function 10 times I get the following for each run:

1)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfQ=

2)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfQ=

3)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfS=

4)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfS=

5)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfQ=

6)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfS=

7)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfQ=

8)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfT=

9)   6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfQ=

10) 6QD+VQrN8xnPaLkk9WJTI6uJsZVHU7Lp5Cl3XndFEfR=

So, 50% of the time I am getting the correct conversion, but it is not consistent, and I have no idea what is going on.  I am running this with Autoit V3.3.10.2 on Windows 7 32 bit. Any insight as to what I am doing wrong? Thanks.

Thanks greatbrains, I believe this fixes the issue you pointed out. My function was not following the base64 rules when there were on odd number of bytes. I still have to workout the 64bit version as thats a little trickier for me.

Beege,

I tried out your new code and it seems to work like a champ with 32-bit.  I haven't tried 64-bit, so I can't give you a definite answer there.

Thanks for the help! Now if I can just get my HTTP requests to work...

It hangs for a minute and gives me an AutoIt error on decode of an encoded and encrypted string. Encoding works fine. Removing the decode method removes the error.

P.S. I tried compiling x86 and trying it through CLI and the process stopped responding.

I'm not sure if it's related, but AutoIt returns "1073741819" when it closes and researching that number leads to a common error.

 

That error corresponds to 0xFFFFFFFFC0000005 which is an access violation error.

This generally happens when you try to access a section of memory that is not available to you.

This happens when you use uninitialized pointers.

You need to update your version of AutoIt to support the new Ternary operator.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

OK, After

1. correcting my serious blunder (On comp with old version...)

2. Modifying input to take a smaller file $sFile = FileRead("Instructions.txt")

3. adding a few more consoleWrites...

ConsoleWrite(StringLen($sFile) & @LF)
$sEncoded = _B64Encode($sFile)
ConsoleWrite($sEncoded & @CRLF)
$sDecoded = _B64Decode($sEncoded)
$sDecoded = BinaryToString($sDecoded)
ConsoleWrite($sDecoded & @CRLF)
 
I get this:

So, looks like encode may work, but it dies on decode

everseeker,

thank you for pointing to the crypt32.dll. That was exactly what I am looking for. Your code is running without errors, when you replace the line

DllStructSetData($tInput, 1, $input_string & 0)

within the function _Base64Decode_MS($input_string) by

DllStructSetData($tInput, 1, $input_string & chr(0))

i.e. $input_string has to be terminated by a null-byte, not a string "0".

      Is there anyway to create an assembly for AutoIT so that I can use that in Powershell or Dotnet supported languages like c#.
      Like I want to use the functionality of _ArrayDisplay of AutoIT in C# by creating a assmbly/library and using that in the target language.

      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.

      I will try to maintain this topic by inserting links in the first post (here) to the snippets to keep track of the snippets.
      My examples are using AndyG's AssembleIt UDF / AssembleIt2 UDF which is here:

      Without the help of AndyG and Eukalyptus I wouldn't be able to create ASM code - many thanks!!!
      Many thanks dudes - you rock! 
       
      I'm a novice in assembler coding - please don't blame me.

      This is a small UDF I put together just for fun that will embed and extract complete directory's in and from your script. It only has two functions, _EmbeddedDirectory_Create() and _EmbeddedDirectory_Extract(). The udf uses Wards machine code functions so they have pretty good speed. The example I set up packs all files located in Autoit Include directory. Both compression and decompression of the directory was less than 500ms on my pc which I was happy with. Let me if you have any problems or questions. Thanks
       
      Example:
       
      #include "EmbedDir.au3" ;Check location of autoit includes Global $sIncludeDir = 'C:\Program Files\AutoIt3\Include\' If Not FileExists($sIncludeDir) Then $sIncludeDir = 'C:\Program Files (x86)\AutoIt3\Include\' If Not FileExists($sIncludeDir) Then Exit (MsgBox(0, 'Directory Not Found', 'Unable to locate Includes Directory')) ;Create embedded directory function Global $sCompressed_Includes = _EmbeddedDirectory_Create($sIncludeDir, '_Extract_Includes') Global $iTime = (@extended / 1000) & ' ms' ;create example file and write extract function to it Global $hExtractExample = FileOpen(@ScriptDir & 'Extract_Example.au3', 2) FileWrite($hExtractExample, '#include "EmbedDir.au3"' & @LF & @LF & _ '$sExt = _Extract_Includes()' & @LF & _ '_EmbeddedDirectory_Extract($sExt, @ScriptDir & "AutoIt_Extracted")' & @LF & _ 'ConsoleWrite("Extract Time = " & @extended/1000 & "ms" & @LF)' & @LF & @LF & _ $sCompressed_Includes) FileClose($hExtractExample) ;Show stats of the directory we just embeded $aSize = DirGetSize($sIncludeDir,1) If IsArray($aSize) Then Msgbox(0,"Directory Details", _ "Size = " & Int($aSize[0]/1024) & 'KB' & @LF & _ "Files = " & $aSize[1] & @LF & _ "Dirs = " & $aSize[2] & @LF & _ "Compression time = " & $iTime & @LF & @LF & _ "Open Extract_Example.au3 to extract") EndIf

      Do not expect a SVG file as Sodipodi, Inkscape or Adobe Illustrator can generate.
      This "converter" doesn't actually trace or convert the image to vector. 
      It just embed the bitmap image within an SVG container.
