Func _AutoMD5_Data_Decrypt...degradeable?

[allSystemsGo]

I am using the Func _AutoMD5_Data_Decrypt to password protect my script. It reads the key from an INI file. It has worked fine for about a month or so. Now suddenly it tells me that the password I type in is wrong. I tried to make a new key with the same password, and it still tells me it is wrong. Does this method "degrade" over time? I am typing the password in as I always have.

Func _AutoMD5_Data_Decrypt($sInput) ; Returns true if passwords match, or false if they don't.
$iKey = FileCopy("\\server\folder\key.ini", @ScriptDir)
Global $sPass = IniRead(@ScriptDir & "\key.ini", "main", "key", "INI NOT FOUND")
_Crypt_Startup()
$sEncryptedInput = _Crypt_HashData($sInput, $CALG_MD5)
_Crypt_Shutdown()
If String($sEncryptedInput) = String($sPass) Then
$sReturn = "True"
Else
$sReturn = "False"
EndIf
FileDelete(@ScriptDir & "\key.ini")
EndFunc ;==>_AutoMD5_Data_Decrypt

No, md5 does not change over time... it just seems to be that you don't return the result.

$bPass = _AutoMD5_Data_Decrypt($sInput)
MsgBox(0, "", $bPass & @CRLF & @error)

Func _AutoMD5_Data_Decrypt($sInput) ; Returns true if passwords match, or false if they don't.
    If Not $sInput Then Return SetError(1)
    If Not FileCopy("\\server\folder\key.ini", @ScriptDir) Then Return SetError(2)
    Local $sPass = IniRead(@ScriptDir & "\key.ini", "main", "key", "")
    If Not $sPass Then Return SetError(3)
    If Not _Crypt_Startup() Then Return SetError(4, @error)
    $sEncryptedInput = _Crypt_HashData($sInput, $CALG_MD5)
    If $sEncryptedInput = -1 Then Return SetError(5, @error)
    _Crypt_Shutdown()
    Local $sReturn
    If String($sEncryptedInput) = String($sPass) Then
        $sReturn = "True"
    Else
        $sReturn = "False"
    EndIf
    FileDelete(@ScriptDir & "\key.ini")
    Return $sReturn
EndFunc   ;==>_AutoMD5_Data_Decrypt

This still does not let me in to the script. Like I said, it worked for a while, and now all of the sudden, it does not work. When I build the key and test the password, it works and returns the same key.

Its isnt better to use external dll ?

Enlighten me.

On the other hand, I can put this code into just a scrap document and run it, and it works...

edit...

Also... I commented out #RequireAdmin, and then ran the script..typed in my password..and it worked. Why does this resolve it...and why did this work for so long with the #RequireAdmin?

Is the ini file being copied when you run it using #RequireAdmin? Could be that when it reruns the script under admin credentials, you're not able to connect to the remote drive. Just a thought.

Could be possible...The main reason that its not working is because its not copying the INI file...It is just weird that it worked for a while, then suddenly stopped.
