This blog features a convenient way of issuing multiple licenses with the same expiry date and enabled features, which can speed up the license creation process and make your work easier.

If you would rather watch a YouTube video of this guide, please watch the following video:

The feature covered in this blog is called License Templates, and you can read the full documentation here.

Start by signing in to Cryptolens, and go to the product you want to create a license template for. Click on “Create a new key” like you normally do to issue a license manually.

Select the features and the expiry date that you want. Instead of clicking on Create, you should click on Save as Template.

Give the license template a name. Notice that the “Parameters” field is already filled out. If you want to customize the parameters of your license template, please read the existing documentation.

When you are done customizing your template, click on Create.

Go back to the product and click on “Create a new key”. You should now be able to see the license template you created in the field called “License Templates”.

To make a new license with the same features and expiry date as you selected for the license template, simply select your newly created license template in that field, and click on the Create button to the right of the drop-down menu.

This method is useful if you, for example, want to issue multiple yearly or monthly licenses with the same features. It is also possible to retrieve the license templates through the API if you prefer to use the API for license creation.

In this blog, we will cover how you can automatically send emails to customers when a license is about to expire. You will be able to select time intervals for the emails and choose to send a copy to your own email as well.

We have also uploaded this guide as a video if you find that more convenient:

This guide is based on a page in our documentation that you can find here.

Setting up automatic expiration emails

Sign in to Cryptolens and head to the Product Page. For an existing product, click on “Edit Features” and scroll down. Check the checkbox called “Automatic expiration notification” and then click on Save.

The feature is now enabled, but you need to tell Cryptolens which licenses are time-limited. This can be done in two ways:

1. You can designate a particular feature to be the time-limited feature, meaning that any license with that particular feature set as true will be treated as time-limited.
2. You can treat all licenses for your selected product as time-limited.

1: To designate a particular feature to be time-limited, simply select the “Time Limited” option in the drop-down menu for a particular feature’s “Type”, which can be found at the top of the Edit Feature Names page. Enable the chosen feature for the licenses you want to send email notifications to. Click on Save.

2: Check the checkbox below the list of features near the top of the Edit Features Names page called “Treat all licenses as time-limited”. Click on Save.

Now that Cryptolens knows which licenses are time-limited, your customers will receive 3 email notifications, one 7 days in advance, one 3 days in advance, and one on the day that the license expires.

Customizing the time intervals

It is possible to customize the number of emails and the time intervals when they are being sent. To do this, head to the Product Page once again, and click on Data Objects.

cryptolens_expirationnotice

Copy the object name above and paste it into the field called “Name”.

By default, the string value is 0,3,7, meaning that an email will be sent 0 days prior, 3 days prior, and 7 days prior to the license expiration date. Simply change this string value to whatever time intervals you want. If you want to send more emails, just add a comma (,) and specify how many days prior to license expiration you want to send an email. For example, to send an extra email 10 days in advance, simply modify the string to be 0,3,7,10. Press on Create when you have chosen your preferred time intervals.

Sending a copy to your own email address

Stay on the Data Objects page if you want to set it up so that you receive a copy of the email that is being sent to customers.

cryptolens_expirationnotice_send_copy

Copy the data name above and paste it into the Name field. In the String Value field, you should provide the email to which you want the copy to be sent. Press on Create.

In this blog, we will discuss how you can add more features in addition to the 8 features that come out of the box when using Cryptolens and our software licensing system. You will also learn how to create feature hierarchies.

This guide is also available as a video tutorial in case you prefer to take in information that way:

The first step is to sign in to Cryptolens and bring up the Product Page. Once you have created a product and a license key, you may already be aware that you can click on the license key to enable or disable up to 8 features.

Let’s suppose that you’d like to add feature 9, or even define a feature hierarchy where you create a module with multiple sub-modules. This can easily be done using Feature Templates, which are described in more detail in our documentation.

Multiple Features Without Hierarchy

The example listed below allows you to add additional features without defining any feature hierarchy.

["ModuleA", "ModuleB", "ModuleC"]

You may change the name and the number of new features in the code to suit your needs. If you do not wish to make any changes, simply copy the code above and head back to the Product Page on the Cryptolens dashboard. Click on “Edit Feature Names”.

Scroll down to find the Feature Template field, and paste the copied or modified code into that field. Press the Save button and go back to the Product Page. When you press a license key, the new features will now appear below the original 8 features. The end result is shown below.

Multiple Features With Hierarchy

Let’s now suppose that you would like to add a sub-module to a particular feature. In this example, you will learn how to create two sub-modules for Module B, but the same logic can be applied to define whatever hierarchy suits your needs the best.

This section begins after the above-mentioned one ends, so if you have not already, please begin with the steps mentioned above regarding “Multiple Features Without Hierarchy”.

Head back to your Product Page on the Cryptolens Dashboard and press “Edit Feature Names”. Scroll down to the Feature Template field to find the code you pasted earlier. To define feature hierarchies, you will have to modify this code slightly.

The following code shows how to create two sub-modules for Module B. Simply replace “ModuleB” from the code in the Feature Template field with the following code:

["Module B", ["Submodule 1", "Submodule 2"]]

As you can see, the first element in the list is the name of the main feature, and the following elements will be the associated sub-modules. Using the same logic, you can define whatever feature hierarchy suits your needs. Keep in mind that you also can define sub-sub-modules.

The following code shows the end result if you just want to make three new features, whereas Module B has two sub-modules:

["ModuleA", ["Module B", ["Submodule 1", "Submodule 2"]] , "ModuleC"]

When you have created your desired hierarchy, hit Save, go back to the Product Page, and click on the license key. You will now see additional features listed below the original 8, with the hierarchy you have defined.

Below you will find what the hierarchy looks like from our example.
