I whole heartedly agree with you. I was only mentioning it as nearly
every couple of months this topic pops up. Since a lot of the people
are small time developers and are wanting to protect their software to
protect their lively hoods, to me it would make sense that there was
collaboration within the community of cocoa developers to create an
open licensing kit so as a community we all benefit.
I will throw my hat in the ring and say if someone want to provide me
with a design spec of how such a system is meant to work, I am more
than happy to implement it in my spare time, as I know in the future
(say 6 months) I will need to integrate licensing into my application.
I posted my last message before I read this, so I need to apologize for
suggesting that you were asking this guy to give away his code rather
when you were actually proposing a group collaboration (which is after
all what SourceForge is all about). As I said in my previous message,
if I decide it is worth the trouble to do an elliptic-curve serial
number thingy I'd be glad to publish it for general use (obviously, as
I said before, such a project would have to be under an open-source
license that permits commercial reuse. LGPL would be the minimum
requirement, but a BSD license would be more comfortable).

Greg,
yes, might be.
But I work self employed. Thus, I earn my money directly
by my own work.
Although I like to give back stuff, I should have the money
component in focus - otherwise, I would die at starvation ;-)
Do you see some solution for this situation? Doing parts
as OpenSource and earning money as well?
Since such a project will certainly not be as big as
MySQL for example, the return in money might be quite
small.

Sounds like a sourceforge project to start!!

How is the general interest in such a system?
We might pack a product and probably sell it.
Currently, this is what's it is doing:
- Generate public/private key pairs
- Generate a new serial number for each new license
- Enter client data and select license type (single/enterprise/..)
- LicenseBuilder as application
- license checker as library
- Interface code
- Handle several applications to be licensed
- Set RSA key size
- Sample project
- Create license files and digitally sing it (using LicenseBuilder)
- Verify license files (in client app)
- Probably Rendezvous based identification of other apps using
the same key
- All stuff is C/ObjC
What do you think?
What would you need?

But to my knowledge there isn't such advanced crackers on the
Mac, is there? :) Although we did have a guy state he could
break 128 bit AES in no time, but hopefully he will only use
this power for good... ;)
AES in such a short time? Quite interesting! Shouldn't he
join NSA?
I think this is the guy he is talking about...
