At the recommendation of my FAE, please consider this yet another request to add/enable support for encrypting images with the MCUBOOT. This feature is already supported in MCUBOOT
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/mcuboot/encrypted_images.html
https://docs.mcuboot.com/encrypted_images.html
and this feature has been requested/discussed in several other threads
NCS encrypted MCUboot images supported?
Adding MCUBoot with encrypted images
How to create an encrypted/signed image
How to encrypt FW for MCUBOOT image update?
As indicated in some of those threads this is a very important feature for many of us to protect IP contained in our images. Please consider adding/enabling this support as a high priority for the next release and let the community know if/when it will be available.
Thanks!
