Simple AntiCopy Component
version 2.15


Description:
------------
Simple AntiCopy Component (SACC) is Delphi remake of my Turbo
Pascal unit AntiCopy
(ftp://garbo.uwasa.fi/pc/turbopa7/antcop11.zip) that provides
minimal level of copy-protecting of executables.

SACC implements only 2 kinds of checks:
- check for application's start drive;
- check for application's full path.

But my main purpose of publishing SACC is to show technique
that may be used by to store information inside .EXE file even
under 32-bit environments.

SACC also includes function (FIND_ID_32 with source) for
finding any ID in file. FIND_ID_32 works only under Win32.
FIND_ID_FROM_END from FIND_ID.DCU (without source) works under
both Win32 and Win16.

You may look also at SACS - Soubatchev AntiCopy System.

SACS is a software system that protects Delphi and BCB programs
from illegal copying. SACS uses new approach to the problem of
protection of software. In its protection method SACS does not
use a call of some checking routine and subsequent conditional
terminating of program. Such traditional approach usually can
be simply cracked. Instead SACS encrypts functionality of
application - event handlers that were set at design time (and
additionally Captions) of various components of main form.
Protected application restores these event handlers and
Captions from binary resource during each execution.

You can download SACS from:
http://www.urvb.ru/sacs/sacs.zip


Usage:
------
Install SACC as usual component.

Or you can transform it into unit and put GO_SACC in the
INITIALIZATION section, so all you must to do to make SACC work
is only to add it into USES clause of application.


How it works:
-------------
All work is performed by GO_SACC method of SACC. During the
first execution of protecting program information is stored in
the protecting .EXE file. During all next executions this
information is checked, and if it does not coincide with the
saved information, OnPROTECT event is fired.

To use FIND_ID_FROM_END function containing in FIND_ID.DCU you
have to rename appropriate FIND_ID.DC? into FIND_ID.DCU.
