Software Protection-2

My previous project about Software Protection was "not welcomed" by freelancers because (maybe) requiring too much skills at the same time.

Therefore I decided to develop on my own a basic project (in VBNet) of Licensing System that easily integrates any software application.

It could be ok but my Licensing System does not fully satisfy me, so I invite a freelancer expert in VBNet and cryptography to propose a better than mine Licensing Solution for trial and activation keys.

The solution to propose must be based on asymmetric license keys.


1) Freelancers are invited to explain (in words, not in code) their proposal and expected price.

2) I will assign the job to the freelancer that in my opinion will propose the best solution and to this freelancer I will send my sample project to modify.

3) No money will be given before checking the validity of the freelancer's code (must be in VBNet). I offer a one-off payment for a finished and working project.

Habilidades: Criptografia, VB.NET
