Best technique to securing license key


What is the recommended ways to securing the licenses key. Hardcoded in the apps someone could just decompile/re it to get the key. Even using beckend server to retrive the key, if the apps already decomple/re the keys could be retrive via packet in network or event in the modify apps.

What is the standard Syncfusion recommended ways and what is the standard developer do to protect this ?

Any one could help

Than you

Hi Herry, 
Thanks for contacting Syncfusion support. 
We requesting to registering the encrypted license key as string in application. We considered this in our improvement to protect the license key. We have logged this as future request and it will implement in our any upcoming release.

Hi Abhinay,

We currently don’t have an option to secure the license keys which is registered in the project. We have implemented this licensing (key) validation system just to avoid our customers using our products inadvertently.

So, you can use this license key directly in your project.

I have one suggestion to implement the registration in such a way that we don't require it to pass the key in our code

We can use in this way like Kendo UI does: 


It helps us to avoid adding it into our code base when deploying into our server :

Hi Abhinay,

Thanks for your update,

Already we have planned to implement the License registration secure process feature at our end, and we will include this with any of our upcoming main releases.

Please get back to us if you have any concerns.
