- 2-On the Generate Signed APK Wizard window, click Create new to create a new keystore. If you already have a keystore, go to step 4. 3- On the New Key Store window, provide the required information as shown in figure Your key should be valid for at least 25 years, so you can sign app updates with the same key through the lifespan of your app.

- Dec 22, 2017 Got your own FXServer, but don't know how t get a license key? LINKS BELOW: Too much trouble hos.
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:
I could finally spot the issue after digging into the python code. The code is failing when calling 'serialization.loadsshpublickey(pubbytes, backends.defaultbackend)' in crypto.py because the python cryptography is calling an old python-cffi module.
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.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.For example,
Note: in production, you would perform this step from within your product.
