Fill in the ‘Activation key’ and ‘Hardware ID’ information (learn how to get HW ID) Click ‘Activate’ to generate the activation code Select the entire code and copy it. This is achievable by product activation (Windows is a good example). Basically, for a customer with a valid license key, you need to generate some 'activation data' which is a signed message embedding the computer's hardware id as the signed data.
Serial Key Generator is application specially designed for software developers to help protect your applications by serial key registration. Just in a few clicks you are able to generate serial. If you are connected to the internet or if the activation fails, you will need to manually activate the software. To manually activate the software, send your license key and hardware ID to support@jollytech.com along with a brief explanation of why you transferring the software if you have activated the software previously. The second step is to create the key generator which will generate the activation key from a given serial number. This generator will be placed in a class called KeyGenerator. This class will contain a function which will apply a simple mathematical function on the serial number to get the activation key. Serial Key Generator is a program with a pretty self-explanatory name - it allows you to generate serial key numbers. It can be used by app developers in order to protect their software against. Laptop Hardware and Software. This so that it will come up with the right product key. Product Key = Product Id. How to Create Product Registration Code.
Serial keys for software programs, more accurately called product keys or installation keys, are needed before you can install almost any popular software program.
Serial keys or key codes are often required during the first part of a program's installation or sometimes after using a program for a certain period of time.
So what do you do when you can't find that special installation code but you need to install the program again?
Without a doubt, a key finder program - a special kind of software tool - is the best way to go if you're lost a serial key for one of your software programs, so long as it's still installed or recently was.
Product key finder programs are software tools that automatically search your computer for the serial keys stored in the Windows Registry or elsewhere on your computer.
For example, when you installed your operating system and other software, the product keys used during their installations were stored, probably encrypted, inside a specific registry key.
See our article on free product key finder software programs for a ranked and reviewed collection of these very handy tools, all of which are free to download, install, and use.
Now, you could manually look in the registry for the serials and install keys yourself, but they can be very hard to find. Not only that, the stored keys are usually encrypted, making what you dig up there completely useless anyway.
Most product key finder programs were originally designed to find the serial numbers and key codes for operating systems like Windows 10, 8, 7, Vista, etc., but many of them find serials and keys for many other programs, too, like office suites, video games, and more.
Even if you think, or know, the program you've lost the key for isn't installed on your computer anymore, you should still try one of the higher rated product key finder tools in our list.
Sometimes,a program will leave the registry keys that contain that program's serial key in the registry even after it's uninstalled, which is why this is worth a try. This isn't usually the case when the program was removed with a dedicated software uninstaller, but it's still worth a try.
If that doesn't work, you're left with digging around for the box the software came in, the email that accompanied the download, etc.
Unfortunately, at this point, your only legal option is to buy a new copy of the program.
In your search for help with lost serial keys, you've probably come across software cracking tools, keygen programs or maybe even lists of free key codes, there for the taking.
It's very important to realize that none of those resources are legal ways of obtaining installation keys or any other unique code designed to protect programs from being pirated.
The only legal way of installing software is by using a valid installation code obtained through a legal purchase of the software program.
In this simple article, I am going to show how you can protect your software from unauthorized copying by creating a serial number/activation key pair based on the physical address (MAC) of the network adapter on the client's machine.
The first step is to get the MAC address of the client's machine. This could be achieved by using the ManagementClass
class located in the System.Management
assembly. We have to add a reference to that assembly to our project, and import it into SecurityManager.vb, which will be the class in which we place the GetSerial()
and CheckKey()
functions. These two functions will be responsible for generating the serial number from the MAC address and checking whether the key entered by the user is valid. As a first step, we define the GetSerial()
function as follows:
This function will give us the unique serial number of each MAC address (not totally unique, but similar to hash function uniqueness).
The second step is to create the key generator which will generate the activation key from a given serial number. This generator will be placed in a class called KeyGenerator
. This class will contain a function which will apply a simple mathematical function on the serial number to get the activation key. In this case, I will use the function f(x) = x2 + 53/x + 113 * (x/4).
Back to SecurityManager.vb, we need to add one more function, which is CheckKey()
. This function will take the activation key as a parameter, apply the key-generating function on the current MAC address, then compare the two keys to see whether they match or not.
One important note left: do not place all of these classes in your client's solution! Remember that the key-generating class is only owned by you.
Now you can use these classes to protect your software. You can also use more complicated functions to ensure more security. The key generator may look like this:
If everything is alright, the user would get the following message.
