Topic: piracy

[jsr]

Hi everybody

If someone writes auto/visual lisp code for commercial use. What are the possible measures to prevent its piracy. When using .NET we can have installation packages/activation codes etc But for lisp code what are the possibilities. Even if we create a .fas file it makes the code unreadable but still it can be easily copied/used etc.

Please guide.

Actually Lisp easier to protect than .NET : )  compile to .vlx, or .fas, 
Get the OS activation code or motherboard serial and go from there

Thanks eAmbiguousOutput

Would you please explain bit more. I want to give the .fas/vlx applications to others who are authorized to use but do not want them to further distribute them to others.

Thanks again.

heres a link to where you can get some of the hardware needed to build a key

Step 1. create a lisp routine in your VLX that can collect a few serials from the hardware.
Step 2, create a lisp routine in your VLX  that can code and decode the serials.
Step 3, create a lisp routine that can generate a request key and  accept an activation key.
step 4, store the activation key.
step 5, at various points in your lisp routine I.e at launch, check that activation key exists and is valid.

something like that

Is the application already written? If not I wouldn't worry about piracy, it's more important to write the application.

Sorry to be harsh again, but keying your software to the OS or some piece of hardware is, hold it - here's that word again --, stupid. Unless people absolutely need your software, which they probably don't, then that is a first class ticket to no sales.

One thing that has puzzled me actually is that surely you need the program to modify itself in some way, else what is to stop the user running the program on another system and the program just going through the procedure as if it was the first time launch?

whoa junior ... you may just need to explain that !!

who are you talking to and why are you being so aggressive ..

Paul's got one of those opinions 

I have one program on the market that has keying, While this had absolutely no affect on sales, it is a real PIA to deal with.

There's lots of ways to handle it. Self modifying code could be one. But if you want to key on the hardware then some sort of hardware hash needs to be sent company so they can send you a key based on it and your name or something.

I did give a warning.

Aladdin had support for Autolisp, if your looking for a commercial solution http://www.aladdin.com/support/hasp/hasp4/legacyapi.aspx

Sorry Its for Mr. pkohut who should not reply if he does not have a reasonable answer.

I think no question is non snece If the purpose is to learn something. One cannot learn if he/she does not ask questions whether reasonable or not. I had a question in my mind so I posted it to forum Now one does not need to worry if I have any application that is valuable for other or not.

Thanks.

Sorry I didn't provide you with the answer you wanted to hear. After rereading what I wrote, I must agree with myself 100%. Again, my apologies.
