I was trying to carry out Hardware locked Licensing.I found the using code from codeproject that creates hardware id(Device Identity)
This code generates Equipment Key
.My aim is certainly to apply strict licensing scheme.As demonstrated in the diagram provided below,I are capable to generate a distinctive device or Equipment ID using the above program code.
Centered on the Device ID or Major,I wish to create an Service Key so that it would be distinctive and can be used only on one machine because the Account activation key would end up being created from that Machines MachineIDHow can that become attained?
Adhering to will be the picture
I hope my doubt is obvious.If not please let me know,I'll up-date the question with even more information

The easy solution
The simple alternative would become something like this. When the consumer buys your software, generate a unique GUID for the license. Let's contact this thelicense key. When the user installs the software, you get yourspecial equipment key, concatenate that with thepermit key, and hash the result. The hash you create will end up being theactivation codethat you're looking for. Store that value on your machine. If the exact samepermit keyis definitely ever utilized to install the software program on another device, you will evaluate the computedservice codefor that set up against the a single you have kept on your machine and refuse the set up if the rules do not really complement.
The Catch
That getting mentioned. the way your current scheme is usually fixed up, you are heading to chance making your customers very distressed. For illustration, if I buy your software program and my difficult drive passes away on me, with your current set up I would have no method to recover my software program. If you're going to do hardware personal structured licensing, you should try out to limit it to the functions that are usually least likely to alter. BIOS.ok maybe you're safe. But hard drive, network card, video card are usually much more most likely to change.
Furthermore, you might want to provide your customers a method to transfer the license to another computer. The way your perform this is certainly possess a custom made activity in your uninstaller that will revoke theaccount activation program codefor the permit so it will no longer be linked to that equipment ID.
Summary
In all of this, the key is usually to maintain issuesmainly because simple as feasible for your customer. There obviously can be a trade-off between security and simplicity of use, but you Perform NOT need to lock out genuine customers and risk alienating them.
All that getting said, there are also plenty of existing commercials choices for managing permits. QLM is certainly pretty great is usually you're ready to covering out the cash. In everything, simply think about the cost of acquiring your software program versus the value of acquiring it.
