https://devzone.nordicsemi.com/f/nordic-q-a/35194/ota-dfu-package-encryptionHello, We are evaluating the nRF5_SDK_v15.0.0 example OTA DFU bootloaders on a nRF52840-PDK. We have generated a signed firmware update package using nrfutil pkg generate .. with a private key.

It is possible to implement encryption of the firmware in the<span>&nbsp;</span>DFU<span>&nbsp;</span>package as discussed in<span>&nbsp;</span><a href="https://devzone.nordicsemi.com/f/nordic-q-a/22375/dfu-firmware-encryption">this thread</a>, but Nordic does not provide any examples or tools for it.</p><div style="clear:both;"></div>
