How about having the option for a DBPro version of a lib File i.e. put all your functions in the lib file have the main structure for your engine in the normal exe but call the functions strait from the lib nice way for ppl wanting to show of code but who might want to keep other parts of the code secret you could use it like a dll but for DarckBasic Commands i may also e-mail mike about this se wot they say.

Technically speaking, you do when using external DLL files. It's an interesting idea though. People would facilitate the option by providing addon functionality but protecting their source code.

my thought exactly you can say have a demo of the lib with a splash screen for users to try but not release code and it cant be modifid
then if they bye it give them the proper lib or code in the lib.

Maybe in later versions of DBPro, this will be an option when compiling executables, like a Password Protected Lib file which you just throw into the user plugins directory.

This is already possible... I believe Hubdule released a tool that does that exact thing. Not sure who actually, but it was pretty recent.

I'm not aware of it but keep the gang informed if you do find it

Yes, it's allready been done. You can get it here.

With this tool you can create code librarys which keep protected code. ... see page for more details.

Too easy code for protecting libs I've cracked it.

"Too easy code for protecting libs I've cracked it."

So did I, but I believe that it IS secure enough for code libs assuming that it is nothing of major importance.

Doesn't that defeat the whole idea of protected Libs anyway lol.

Put it this way, I reckon that 9/10 users here couldn't crack it. (Unless I missed a really easy way of doing it)

Mr N is Russian, which explains things Just to proove it though, can you post some of the source from the protected sample?

At the end of the day though, I cracked the compiler, not the DBL pre-processor, so there is little that Hubdule could have done about that.

i have a mate who cracked them too, but he's also cracked .lib dll's and has said that the protection is about the same - so i'm not bothered ... i thinks it safe enough

It is better to say that 99 from 100 can't crack such things.

@Hubdule
Sorry, I can't help you because of specual methods I used. Simply I worked for FBI in Russia then I was young (..and I was clewer enought to deside not to continue this work )

@Rob
Simply

@Doesn't that defeat the whole idea of protected Libs ...
Every soft can be cracked not only Libs protector. It had been proved.

I think Lib Protector is bad idea util there is person, who has power to uncode such libs without a permission. But may be I'm wrong.

You use "Russian" as an adjective I'm offended.

@Hubdule

You COULD do a CRC check on the compiler to verify that it has not been altered in any way, but in this case you would need to release a new pre-processor for every version.

Any software can ultimately be cracked though, and considering the limits which you had, you did well

Why are you offended if I use Russian as an adjective, it simply means the country that you come from, you could say I'm english, and I wouldn't mind.

The biggest problem with protecting source code is that you are trying to protect it from programmers - the very people who put the hex in hexadecimal...

If you're writting protection to lock out the 'computer wizard' three doors down - that's a piece of cake - but to actually protect a piece of code from somebody who knows what their doing... you must remember that even PGP encoded documents can be read by the person whome it is meant for...

Therefor your only meens of distributing source code securely is in compiled form, and even then if your program reaches enough people and/or is good enough it will get hacked, edited, have it's protection removed and possibly even find somebody writes a 'mod' for it...

If you really really really want to be secure then close your bedroom door and turn the computer off...
