The Enigma Protector is a powerful tool that was designed for
complex protection of program modules. Program modules include
following types of objects:
- Win32 Portable Executable file (*.exe);
- Windows Screen saver files (*.scr);
- Dynamic Link Libraries (*.dll);
- 32 bit ActiveX control files (*.ocx);
- .NET executables (*.exe).
When we say "protection" we mean realization of two major ideas.
First one is integration of "try before you buy" conception support
system into the program module. Second one is protection of
machine code of program module from analysis and cracking. As
can be seen, the protection is realized in different, but
nevertheless greatly interrelated aspects, which are protection of
developer economic interests and technical protection of the
program product.
The Enigma Protector has advanced scheme of registration keys
generation:
- Comfortable interface for creating and verifying of registration
keys. You do not need to search any safe decisions how to
generate registration keys for customers. The Enigma Protector
helps you to create keys with very safe algorithm like RSA
512-bits key length!
- Special Enigma API. Enigma API is the set of special functions
to make communication between protected program module and
the Enigma loader. It gives access to full information about
registration keys, current trial parameters and so on.
- Hardware locking of registration keys. This perfect feature helps
you to generate registration keys for particular computer only!
The registration key generated with the hardware lock function
enabled will works only on one PC you have chose.
- Time limited registration keys. If you need to limit time of usage
of registered version of module, just create time limited
registration key!
- Registration dialog designer. Allows to customize registration
dialog that is shown at the module startup!
The Enigma Protector includes few unique tools for managing of
licenses:
- Registration manager serves for storing of licenses generated
for the registered users. Once you generate a registration key you
can simply add this information into internal database.
Registration manager provides you to create/edit registrations
and customers records.
- Mailer serves for automatically generate and send emails to the
users that are stored in the database. For any software developer
is the common thing to send notification emails to the registered
users (for example, if the newest version of the software has been
realized or new registration scheme has been implemented),
Mailer provides you very simple way automatically generate and
send emails.
The Enigma Protector has wide range of features to limit time of
module usage:
- Executions, days, date, time limitations. The main conception of
shareware is "try before you buy". The customer should see how
the application works and what features it has. Let's show these
features but do not forget to limit usage time to increase
motivation to buy application.
- System clock control. This feature is used to control system
clock reversing. It helps you to avoid not honest customers.
The Enigma Protector has a lot of features to make your software
resistant to cracking:
- Anti-debugger tricks. Debuggers are the special tools that allow
to reverse source machine codes of executed module. All reverse
engineers use these tool to understand how your module works or
how the protection of module works. Using of this feature helps to
avoid simultaneous execution of protected module with debug
tools.
- Control sum checking. Control sum is a special data which helps
to understand is the data region modified or not. Every crack (e.g.
removing of protection) needs to modify some of machine code
region, The Enigma Protector is able to check is the sources
modified and if it is then make alert. The Enigma Protector checks
not only machine codes of protected module but the own sources
too!
- Set startup password. Sometimes you need to limit count of
users which are using protected module to particular group. Using
of startup password feature is the most safe decision.
- External files checkup. Allows to check version and (or)
attributes and (or) hash (checksum) and or date of external files.
- Processes checkup. Allows to set a list of dangerous tools that
could not simultaneously work with protected module (this feature
can help to do not execute protected module if sceencaptures
tools, or any monitors or debuggers are running).
- Virtualization tools checkup. Allows to stop execution if the
protected module is running under Virtual Machine like VMWare,
Virtual PC or etc.
- Here are also checkups of Installed services and Windows
version.
- Additional features. They checks up number of simultaneous
executed copies of protected module, file name of module, disk
type on which module is executed.
- Hard modifications of import table of executable. Nobody will
know what import libraries uses your module.
The Enigma Protector has features to help programmer to add
beautiful things into existing module without writing any additional
sources strings:
- Splash screen. Adds splash screen to module startup. Choose
your own picture to show it while module is starting.
