    Question Executable Obfuscator

    Hi, anyone know an Executable Obfuscator, or something like it?
    Iīm 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 canīt 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.

    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
