I found a copy at [1] that has the following header * Copyright (C) 1999-2003 Cronyx Engineering. * Author: Serge Vakulenko, <[EMAIL PROTECTED]> * * Copyright (C) 2000-2004 Cronyx Engineering. * Author: Roman Kurakin, <[EMAIL PROTECTED]> * * This software is distributed with NO WARRANTIES, not even the implied * warranties for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. * * Authors grant any other persons or organisations a permission to use, * modify and redistribute this software in source and binary forms, * as long as this message is kept with the software, all derivative * works or modified versions. This seems to allow deobfuscation, I took a quick stab on deobfuscating it and cpddk.h contains the structures with full names/labels so it should not be a total dead end, but the second problem is that there are some large firmware blobs that will be hard for anyone to decode. /jp (And no I won't do a full deobfuscation, it was more of a mental game) [1] http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/cp/cpddk.c?rev=1.1 -- jens persson # I met someone who looks a lot like you <[EMAIL PROTECTED]> # She does the things you do Mäster Olofsväg 24 # But she is an IBM.
