#include
$xz=_Crypter("Data to encrypt",0)
MsgBox(0,"k",$xz)
$xz=_Crypter($xz,1)
MsgBox(0,"k",$xz)

Func _Crypter($String,$Operation)
_Crypt_Startup()
Switch $Operation
Case 0
$x=_Crypt_EncryptData($String,"akciok",$CALG_RC4)
Return $x
Case 1
$x=_Crypt_DecryptData($String,"akciok",$CALG_RC4)
Return $x
EndSwitch
_Crypt_Shutdown()
EndFunc

Ok, why the hell this is not working. No sense at all. :ranting:

And why would I need _Crypt_DeriveKey?

Examples on help file doesn't explain it. What's for? (Please don't copy-paste from help or link me to help file...

Hate to say this, but you need to read the help file more thoroughly. Here's your script updated to work properly.

#include <crypt.au3>

$xz = _Crypter("Data to encrypt", 0)
MsgBox(0, "k", $xz)
$xz = _Crypter($xz, 1)
MsgBox(0, "k", $xz)

Func _Crypter($String, $Operation)
    _Crypt_Startup()
    Switch $Operation
        Case 0
            $x = _Crypt_EncryptData($String, "akciok", $CALG_RC4)
            Return $x
        Case 1
            $x = BinaryToString(_Crypt_DecryptData($String, "akciok", $CALG_RC4)) ; <<<<<<<<<<<<<<<<< the function returns a binary string
            Return $x
    EndSwitch
    _Crypt_Shutdown()
EndFunc   ;==>_Crypter

From the help file:

Remarks

The decrypted data is always returned as a binary string even if the encrypted data is in fact a string (cast with BinaryToString)

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.

Daaaaaaaaaaaaamn....

Thank you BrewManNH, really appreciated your kindness.

Any further info about DeriveKey?

What's the use of derive a key from a password and use it as a password?

Thanks
