Server side application to decode NTAG424DNA link generated with non default Master KEY and App KEYS

[mimmolf]

Hi,

I am using NTAG424DNA to connect securely to my web application and exchange some information stored into the file data.

I used the sdm-backend application https://github.com/nfc-developer/sdm-backend that works fine if the Master key is the default one (with all zeros) but it doesn't work if the Master key or App keys are changed.

Is there any available application that can be used to decode the url and returns the UID/counter and file data informations?

Thanks, regards

Mimmo

Hello @mimmolf

Hope you are doing well.

I am not fully aware of the functionality that the application you referred offers; however, I can see that, as you pointed out, it does not support personalized authentication Keys. Perhaps you can contact the developer of that repo to see the support they can offer for your setup.

Unfortunately, there is no Backend application I could recommend, it should be implemented by the user. Perhaps you could take a look at the Secure Services for the NTAG Product Family | NXP Semiconductors > NTAG Secure Cloud Platform Service; for more information on this service, please try contacting the email address specified in that webpage.

Regards,
Eduardo.
