Hi..

I'm trying to get PHP Screw working on Windows thru Visual C++ compiling
it as a windows DLL, everything works except it doesn't actually replace the
fopen function, it seems to ignore that command. I would really like to get
this working, I have a project that you can look at if you are interested:

http://koula.co.za/screwdll.zip

I am creating files in c:/ to check if a function runs, and only the
pm9screw_open
doesn't run, when replacing zend_open with it

Thanks if you can help

Regards
Andrew

What is PHP Screw ?
What are you trying to do?
Let's have more detail and more incentive to actually download and
look through the zip file.

Hi,

Sorry... PHP Screw is a module to encrypt your PHP files so you
don't distribute the source code. It works perfectly in UNIX, but
im trying to convert it to windows. My conversion compiles etc
fine, but it doesn't overwrite the zend_fopen function, so I havn't
been able to get it to work properly yet..

Just a quick note for people considering using PHP Screw: It is
absolutely trivial to decrypt such a file as the encryption algorithm is

datap[i] = (char)pm9screw_mycryptkey[(datalen - i) % cryptkey_len] ^
(~(datap[i]));

See <http://www.schneier.com/crypto-gram-9902.html#snakeoil> for an
essay by Bruce Schneier of what he thinks of home-grown crypto :-)
