Hashing a string from @ScriptDir gives strange results

Hello,

got myself into situation i don't understand:

#include <Crypt.au3>
$hash = _Crypt_HashFile(@ScriptDir & '\file1.txt', $CALG_SHA1)
ConsoleWrite($hash)

results in "EÄé™Ë‡%“g1}…‡ÌÒÅ>Exit code: 0    Time: 0.04879". What is wrong?
 

Now the interesting part - using same code as above and additionally using full path:

#include <Crypt.au3>
$hash = _Crypt_HashFile(@ScriptDir & '\file1.txt', $CALG_SHA1)
$hash2 = _Crypt_HashFile('C:\Users\Lauris\Documents\AutoIT projects\Autoupdater\file1.txt', $CALG_SHA1)
ConsoleWrite($hash&@CRLF&$hash2)

results in correct output
"0x1845C4E999CB87259367020131127D8587CCD2C5
0x1845C4E999CB87259367020131127D8587CCD2C5>Exit code: 0    Time: 0.04859"

Laurynelis,

Add a @CRLF to your consolewrite in the first example and you'll get the correct results.

edit: Must be something in the way console is interpreting the non terminated line.  This also produces correct results...

#include <Crypt.au3>
$hash = _Crypt_HashFile(@ScriptDir & '\file1.txt', $CALG_SHA1)
ConsoleWrite($hash & ' ')

this fixes it as well:

ConsoleWrite("" & $hash)

 

*Its because it is evaluating the input as a number, and that number is huge.  All those solutions change it to string.

 

ConsoleWrite(string($hash))

The help file fails to mention that the functions returns a binary variant.

Implicit variant conversions explain the issue, as already mentionned.
