Data structures / pointers

[Skitty]

I'm trying to retrieve the description of a previously crypted string from cryptprotectdata but I don't know what I'm doing wrong.

Can anyone help?

Local $Hash = "[String previously encrypted by cryptprotectdata API]"
Local $Description = DllStructCreate("wstr");wrong structure type?

Local $aReturn = DllCall _
( _
    "CRYPT32.dll", "int", "CryptUnprotectData", _
        "ptr", DllStructGetPtr($BLOBIN), _
        "ptr", DllStructGetPtr($Description), _; this is where something must be going wrong
        "ptr", 0, _
        "ptr", 0, _
        "ptr", 0, _
        "dword", 0, _
        "ptr", DllStructGetPtr($BLOBOUT) _
)
ConsoleWrite(DllStructGetData($Description, 1) & @CR)

I think you'd use an array instead of a wstr.

So I guess something along these lines:

Local $Description = DllStructCreate("byte[512]") but that may not be perfect syntax.

Wait, didn't I reply to you?

I'm pretty sure I had replied to your post saying that I've tried that and was unsuccessful, I wonder what happened to it...

But anyway, I'm still trying to figure this out, whenever I crypt a string and add a description to it, I just cant find out how to get it back, this is a real bummer..
