Manual key provisioning for nrf54l15

Hi All,

I have a question and slight confusion as referring to couple of links.

Performing KMU provisioning: Here we are highlighting provisioning of private key up to 3 counts

and 

Exercise 2 - DFU with custom keys - Nordic Developer Academy: Here we are highlighting provisioning of public key

So, creating slight confusion here.

I believe it's a private key only that is provisioned. However, a concern here as we are manually provisioning private key means we cannot use this method during production.

Maybe I am missing something here. 

Can anyone please help?

Thanks!

  • Hi Nilesh,

    Apologies for the delay as it was a long weekend here in Norway.

    From both the links, you can see that it is the public key that is being provisioned. The private key is used to sign firmware images and must remain secure and confidential. 

    So,  If you see references to provisioning a .pem file, just make sure that it is the public key portion being uploaded, not the private key itself.
