Developer's overview for generating license keys and activating software. Mirrakey is an ActiveX dll that you can add to any COM compliant development project to generate and authenticate license keys for your software application. Mirrakey is flexible and includes an in-built client-side license key manager interface that you can customize with your logo and relevant inputs for key validation. The License Manager window (if you choose to use it) will save the registration information on the client computer to an XML file for validation by your application.

The input parameter or properties are string values that you can use for any values you require to identify your software, user or both. The three properties have friendly names (ProductName, SerialNo & UserName) but you can provide any string value for all or one of these properties to generate a key. Of course, to generate a unique key, at least one property input must be unique. The decision regarding the input values is your decision based on your licensing requirements. For example, you could use one of the following scenarios: ProductName = 'MyWidget' UserName = customername@myemail.com ProductName = 'MyApp' SerialNo = '12345676' (this could be a random number/string generated on installation of your App). ProductName = 'MyProgram' SerialNo = CPU ID (you could use some hardware identifier on the user's computer) These are just some examples because the input parameters are up to you as the software developer. Those parameters will depend on whether you generate the key manually on request or use a website to automatically generate the license key and send it to the client.

If you generate the key manually you can obviously enter the properties at that time but more likely you will want to automate the process and generate the keys on a website and send them to the client. Typically this would occur after payment authentication.

After payment authentication, Mirrakey will generate the license key by calling the 'GenerateKey' method using one or more of the relevant properties (ProductName, SerialNo & UserName) you have provided.

The license key is then sent to the client (usually by email) where they enter the information into the Mirrakey License Manager form or a custom form you have created. If you choose to use the in-built License Manager form, you show the form by calling the 'ShowLicenseKeyManager' method. The license information is then saved when the client enters the correct information and clicks the 'Register' button on the License Manager form. The information is saved to an XML database and can be optionally encrypted. With the license information saved on their computer, you can easily authenticate your software by providing the known license properties and calling the 'ValidateKey' method, which will return true or false.

This is done by using the same 'GenerateKey' method after setting ActivationLicenseKey and ActivationUserID properties. The ActivationCode can then be added your license file using the AddActivationCode method making it easy to validate activation locally when your software starts or invokes specific features.
