Using SSH Keys for License generation and validation in.NET Applications Demos and Slides of my session about R and DataScience at ATD12 conference GPdotNET v4.0 Beta 3 has been released. The machineKey element in the ASP.NET web.config file specifies the algorithm and keys that ASP.NET will use for encryption. By default the validationKey and the decryptionKey keys are set to AutoGenerate which means the runtime will generate a random key for use.

This is an example of creating a license activation server using PHP. Thisserver allows you to utilize Keygen 100% behind-the-scenes, so your userswill never interact with Keygen's API directly—only through this server.
This example application is not 100% production-ready, but it shouldget you 90% of the way there. You may need to add additional logging,error handling, integration with your payment provider, deliveringlicense keys via email, etc.
Running the example
First up, configure a few environment variables:
![Using Using](/uploads/1/2/6/8/126882235/338337400.png)
You can either run each line above within your terminal session beforestarting the app, or you can add the above contents to your
~/.bashrc
file and then run source ~/.bashrc
after saving the file.Next, start a local PHP server:

Configuring a license policy
Visit your dashboard and create a newpolicy with the following attributes:
You can leave all other attributes to their defaults, but feel free tomodify them if needed for your particular licensing model, e.g. changethe
maxMachines
limit, set it to floating = true
, etc.Creating a license key
From a web browser, access http://localhost:3000/generate.php. You will needto provide an
order
query parameter for license creation to succeed. Theresponse will contain the new license key in plaintext.Using Key To Generate Validation Pdf
For example,
Note: in production, you should verify that the order ID actually existsand has not already been used to generate a new license key. Ideally, the
generate.php
page should only be accessed by your payment provider aftera successful order.Activating a machine
From a web browser, access http://localhost:3000/activate.php. You will needto provide a
fingerprint
query parameter, as well as a key
query parameterfor machine activation to succeed.For example,
The
fingerprint
query parameter is what will identify an individual machineto determine whether or not it is allowed to run your product.Note: in production, you would perform this step from within your product.
Validating a license key
Once a user's license key has been activated, they can validate it by accessinghttp://localhost:3000/validate.php. You will need to provide a
fingerprint
query parameter, as well as a key
query parameter for license validationto succeed. A valid license will return a HTTP status code of 200
, whilea failed validation will return 422
, along with a reason for the failure.Using Key To Generate Validation Form
