licensing

What is the best and most secure way to license software? Is there an existing program for doing so? I want to sell a script of mine, but I want to make sure that users cannot redistribute or sell it themselves (of course, if they deactivate the registration on their own computer and choose to resell, that is their choice). The software language is VB.net. Since I am not sure whether or not I could host a registration database of any sort, is there any way to keep licensing self-contained securely? I would like the user to be able to download the demo and be able to upgrade to the full version

I've seen some software (a Joomla component, to be exact) for sale on a web site. The web site says it is licensed under the GNU GPL2. However it also says you need to pay for every site you use the software on (with bulk discounts).

My mouth fell open when I suddenly saw this exception message: The free-quota limit on '6000 Redis requests per hour' has been reached. Please see https://servicestack.net to upgrade to a commercial license. What if I published this site? Practices like these are simply revolting! There is no console warning or whatsoever about not having any license. It's like having an 'open

What is the best way to secure the use/loading of a DLL with a license file? titanae A couple of things you might want to consider: Check sum the DLL. Using a cryptographic hash function , you can store this inside the license file or inside the DLL. This provides a verification method to determined if my original DLL file is unhacked, or if it is the license file for this DLL. A few simple byte swapping techniques can quickly take your hash function off the beaten track (and thus not easy to reproduce). Don't store you hash as a string, split it into unsigned shorts in different places. As

You open-source your app under GPL v3. The app is only for internal use in your company.
