. Introduction This article is about a license key generation program. As you know when you get a software package it usually requires a license key. The keys that are generated show various pieces of information, such as product, customer and version. With this program and library you can create the key and later read it in to validate that the correct key was used. This is used not only for selling commercial products but also in deploying enterprise applications.

With a license key you can turn features on and off for each customer, have product feature expire at the end of a demo period, or any other type of enabling or disabling you desire. Since I wanted to put this code in CodeProject I adhered to using NUnit as my unit testing tool, NDoc as my documentation tool, and FxCop as my code analyzer. In this project, I created an interactive test tool to test the various features of the library. Background There are various ways to create keys; this article shows one such way. Another site that does License keys is. Using the code The license keys are created with either a base 10 or base 16 integer data set.

Most keys are base 16 for all of the numbers. The license key template is a string of characters that represent what actions will be taken when the key is created and decoded. Two types of templates are Bytes and Bits.

Bytes are used when the key will be a simple key that does not require a lot of fields and data encoding. Bits are used when there will be more fields and the encoding will be harder to decipher. This version requires that all fields be on the byte boundary so it is a little easier to decipher the end result.

The next version will not be aligned on a byte boundary so it will be harder to decipher. The key template has two characters that are defined by default. The x character states just a filler or random number. The c character defines a checksum character. These two characters are the only two that are reserved. A sample of the template and the resulting license key for Byte values and Decimal numbers are: xxxxxxxx-xx-xxxxxxxx-xx 6965891517-23 A sample of the template and the resulting license key for Bit values and Hex numbers are: xxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxx BC017-1-160C4 With this library you can define the tokens that you want to replace real values with, such as product numbers, version numbers, serial numbers, or user counts. GenerateKey gkey; gkey = new GenerateKey; gkey.LicenseTemplate = ' xxxxxxxx-xxxx-xxxxxxxx-xxxx'; gkey.MaxTokens = 0; gkey.UseBase10 = true; gkey.UseBytes = true; gkey.CreateKey; finalkey = gkey.GetLicenseKey; The above example shows how to create a license key that has no tokens, uses base 10 numbers, and uses bytes for the template definition.

Since no tokens are used, it really just creates a random number. GenerateKey gkey; gkey = new GenerateKey; gkey.LicenseTemplate = ' vvvvppppxxxxxxxxxxxx' + ' -xxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxx' + ' -xxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxx'; gkey.MaxTokens = 2; gkey.AddToken( 0, ' v', LicenseKey.GenerateKey.TokenTypes.NUMBER, ' 1'); gkey.AddToken( 1, ' p', LicenseKey.GenerateKey.TokenTypes.NUMBER, ' 2'); gkey.UseBase10 = false; gkey.UseBytes = false; gkey.CreateKey; finalkey = gkey.GetLicenseKey; This example shows how to create a license key that has two tokens.

The first token sets the version to use a token of v with a value of 1. The second token sets the product to use a token of p with a value of 2. It also uses hex numbers and bits for the template definition. The various token types are NUMBER, CHARACTER, and DATE. In NUnit, the NUMBER and CHARACTER types are used extensively. I have not finished DATE as of this article but will do so later.

At this time I am not sure if you need it since you have NUMBER available to use. The original reason I thought DATE might be of value is it might pack better than just using numbers. Some of the additional classes that I had to write to support the license key generation are a random number generator, a data type parser, a number display class, and a checksum class. The random number class uses the C# Random class but adds some additional methods to support the requirements. The methods are:. GetRandomNumber Get a random number. SetMaxLength Sets the max length of the number.

The checksum number class uses checksum routines that are pretty basic. Additional advanced algorithms can be added simply by adding the routine and an enumerated type. The methods are:.

ChecksumAlgorithm Get/set the property to use the different checksum algorithms. ChecksumNumber Gets the checksum number. CalculateChecksum Calculate the checksum based on the selected algorithm.

Since so many variations of a license key can be done I did all of the unit tests using NUnit. Another advantage of NUnit was that if I fixed something in one area I could also make sure that I did not break something or another. Since the keys are using random numbers, I iterated thirty times in many of the tests to make sure the numbers matched.

As part of the tests, I also decoded the same key to make sure that whatever I encoded I also decoded the same value. When you open the solution, you will notice there are three projects. One is the library so that when it is built anyone can use it. The second is an interactive test program so that you can test individual license keys and tokens. The third is the NUnit project so that you can add, run and debug the unit tests. Points of Interest Doing bit shifts in C# is somewhat different than C in that they are not allowed on chars only on integers.

The time saving that I made by doing the entire unit test in NUnit was well worth the effort, I never would have had this much code coverage without using it. The Help system is written using NDoc so that is it in a standard format. Not to mention it is easier to search and use. For the library part, I ran FxCop routinely to make sure many of the best practices are adhered to.

History If everyone is interested I can put the code at SourceForge as well. This way others can add, update or use the source code. I plan on adding the ability to set tokens on bit boundaries and not just on byte boundaries. Mohsin Afzal 14-Jul-15 23:17 14-Jul-15 23:17 Hi All, I need to give license for my project. Once my project(software) is installed.i need to track the date when it is installed then from that date after 3 Months.should display the messages 3 Months Trial version software expires.

Or it will stop the software so that i can protect my software. I am new, and this is my first application, if possible then please provide me code or full description How to implement this part in Windows application in C#.net Thanks mohsinafzal.s13@gmail.com. Alia Butt 26-May-15 11:23 26-May-15 11:23 No doubt, Windows 7 Professional 64bit is a Pro version of Microsoft, Which has all recommended functions, So you can install it with low specs of your system, As you can see; 1GB Processor, 512mb Ram and 8Gb HDD is required to install Windows 7 Professional, But with these low specs, Your system will not slow, If you're not using any apps, which required high specs.

Microsoft released many new OS, But Still I'm using it and suggest for other to install with its legal license, Which you can buy cheap at: ODosta Store Using Boot into UEFI mode or legacy BIOS-compatibility mode when installing Windows from your USB, DVD, or network location, You'll have full command to use it after having a legal version. Legal OS for windows or Mac will be full & functional with Microsoft updates and make your data safe and sound.

Hope to understand. HiDensity 30-Jul-14 9:01 30-Jul-14 9:01 Maybe I am blind, but I cannot get the benefit of this piece of code. Well, it creates something that might be a serial number, but this thing is randomized, does not encrypt any given information, etc. It looks to me, like it is a pretty neat string-generator, using some static tokens. What does the 'Decrypt' thing do? Well, it checks back to the used template. But a template with '4444' and '5555' blocks in a serial number is quite useless.

I would really like to use it, but in fact I cannot see any usefull usage. AarKayCee 16-Apr-11 5:26 16-Apr-11 5:26 Hi Donsw, Many thanks to sharing source for license key generation. But nunit.framework is missing from downloaded source. I also felt that you should have included a text file to describe how to use the software.

So as one can make it use for the purpose. It will be nice of you if you also provide availability of missing nunit.framework so as user like me can do further brain wracking. Since it is incomplete so can not use it. Looking forward for your valuable guidance so as users can use it giving thanks forever. Cbuffett 20-Feb-07 15:14 20-Feb-07 15:14 Is there a way to encode random text (say a customers name, the date of key generation, etc.) into the key, along with some value that can be checked to validate the key? Given the following pieces of text, generate a key for client. Give that key to the client as part of the product.

Customer Name Date Specific value known only to myself (private key if you will) The only thing that actually needs to be parsed and validated from the final key is my 'private key'. The rest is just superfluous, but can be used to check which key belongs to which client. Cheers, Chris.

A55imilate 9-Oct-06 3:34 9-Oct-06 3:34 I'm not really following this at all. I can create a key using the test app, how do i then add some validation to my app to confirm the key is valid? Ie this generates a key GenerateKey gkey = new GenerateKey; gkey.LicenseTemplate = ' xxxxxxxx-xxxx-xxxxxxxx-xxxx'; gkey.MaxTokens = 0; gkey.UseBase10 = true; gkey.UseBytes = true; gkey.CreateKey; string finalkey = gkey.GetLicenseKey; 707-057 How do I then verify that key when my applications runs? For example i have a textbox and the user enters this key. On the buttonclick event what function do i call to get a true or false back?
