https://devzone.nordicsemi.com/f/nordic-q-a/78583/aes128-from-softdeviceI&#39;m using a nrf52810 with limited flash size especially after adding a UART bootloader DFU and S112. I added uECC for connecting security. Now I need AES128 for my own application design. I can&#39;t afford to add any of the other crypto backend like embedtlsen-USTelligent Community 13Sat, 14 Aug 2021 12:33:41 GMThttps://devzone.nordicsemi.com/thread/324928?ContentTypeID=1Sat, 14 Aug 2021 12:33:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:15b5c5cf-5bbd-492b-b878-c02244f2794bdtran11<p>Thank you. I&#39;ll give that a try.

You don&#39;t want to use ECB directly in most cases where encryption is required.</p><div style="clear:both;"></div>
