VC6 compile error(用VC6编译时不能通过)

Anonymous — Thu, 22 Nov 2007 04:42:49 -0000

用VC6编译时不能通过，出现下面的错误，不知道怎么调整

\php_screw.c(59) : error C2491: 'pm9screw_compile_file' : definition of dllimport function not allowed
\php_screw.c(79) : error C2198: 'org_compile_file' : too few actual parameters

PHP CLI cant execute encrypted .php

Jose Rey — Sun, 21 Mar 2004 17:44:52 -0000

In CLI mode the output of .php files arent decrypted, raw content
are displayed.

show_source() shows the source

Jarkko — Mon, 08 Dec 2003 12:18:21 -0000

show_source ( string filename ) shows the source which
makes this whole software useless.

Security issue

Anonymous — Sat, 03 May 2003 01:15:27 -0000

To decrypt an encrypted php script is enough to follow
the following steps:
- open php_screw.so with a disassebler (for example ldasm)
- find the keyword pm9screw_mycryptkey
- take the "file offset" info
- open php_screw.so with an hexeditor (vi, hexedit,
whatever, ...)
- go to the offset taken from ldasm
- read 10 bytes

You have the key to decrypt php-screw encrypted scripts

than...
- use the following code to decrypt the script:

FILE *fp;
char *data;
char *res;
int len;
int i;

fp = fopen(encrypted_script, "r");
len = fseek(fp, 0L, SEEK_END);
fseek(fp, 0L, SEEK_SET);
fread(data, len, 1, fp);

for(i = 0 ; i < len ; i++)
{
res[i] = ~(data[i] ^ pm9screw_mycryptkey[(len -
i) % (sizeof(pm9screw_mycryptkey) / 2]);
}

... encryption should first of all secure...

why don't use a well known secure cipher like 3DES ,
Blowfish, Twofish, CAST, etc.?

error while loading shared libraries

missing configure script in distribution

Anonymous — Fri, 11 Oct 2002 07:07:56 -0000

The code for 1.2 does not compile due to a missing
configure script. I had to manually create a Makefile
from scratch, which took several hours, in order to get
this stuff to compile. I'm using a stock Red Hat 7.3
Linux box.
