HEX to ASCII

Recommended Posts

bahjat

I have a code that takes in Hexadecimal keys and turns them into ASCII keys, the problem arises when you don't have a space in the middle of the hexadecimal keys. 
I was wondering how would i change the code so that it recognises hexadecimals even when they don't have a space in. 
If you don't understand i will exaplain it in a different way, my code recognises the hexadecimal value "65 68" it however does not recognise the hexadecimal value "6568" how do i make it recognise the later. TY for reading

;***** Hexadecimals to ASCII*****

#include-Once
#include <MsgBoxConstants.au3>
#include <Crypt.au3>

$v2 = 65
$HexadecimalsToASCII = ChrH($v2)
$Ascii2Hex = AscToHex($HexadecimalsToASCII)
$v5ar = Chr($HexadecimalsToASCII);char

MsgBox(0,"Hex to ASCII",$HexadecimalsToASCII)

Func ChrH($strString)

    Local $v5=""
    $A1 = StringSplit($strString, " ")
    For $count = 1 To $A1[0]
        $v5 &= Chr(Dec($A1[$count]))
    Next
    Return $v5
endFunc


Func AscToHex($strString)

    Local $ah=""
    For $count = 1 To StringLen($strString)
        If StringLen(Hex(Asc(StringMid($strString, $count, 1)),2)) = 1 Then
            $ah &=  "0" & Hex(Asc(StringMid($strString, $count, 1)))
        Else
            $ah &=  Hex(Asc(StringMid($strString, $count, 1)),2)
        EndIf
        If $count <> StringLen($strString) Then $ah &=  " "
    Next
    Return $ah
endFunc

Local $v = "45 49 555657 6869"
Local $s = _HexToString(StringStripWS($v, 8))
MsgBox(0, "", $s)
Local $check = _StringToHex($s)
MsgBox(0, "", $check)

​i am sorry, i don't understand?

Also when i run the program it says "Hextostring" is an undefined function and "stringtohex" is an undefined function too. What headers do i need to include to make this operational
