Executable Obfuscator

Hi, anyone know an Executable Obfuscator, or something like it?
I´m writing a program that expires.

The problem is progarms like OllyDGB that show MUCH information abaut the exe.
Can trace Strings and switch conditions.

Change a JE to JNE is disastrous.

I saw vary time ago about EXE Obfuscators and "Hidden Strings", but i can´t find nothing.

I thought encrypt all strings via Code, but the code turns slow.

I know that is impossible a 100% Protected system, but a good protection can be sufficient for a small application.

I hope Any help
Thanks

Take a look at CryptoLicensing For ActiveX (http://www.ssware.com/cryptolicensin...ensing_ocx.htm) - it has a Anti-Debug+Anti-Tracer setting which detects when app is being run under debuggers tracers such as OllyDbg, WinDbg. It should give you good protection against this.

Moved To General Developer

Sory by wrong place.

Thanks man...
i will try to do the same (anti-debugger/tracer) by myself...
some one know something like this?

Well, I imagine they work well enough to deter any "casual" hackers, but if someone is determined to get to your code, or determined to write a bypass to get around your licensing system they will do so.

Off topic, you a chemistry major/professional? Your user name is the make up of sulfuric acid is it not?

^^ About topic:
I know, about 'casual' hackers, they are my 'focus'.

About my name, only a 'normal' student that likes chemistry, thats a good way to get 'strong' passwords and help to study for tests xD;

PS: "Your user name is the make up of sulfuric acid is it not?" yes
