https://devzone.nordicsemi.com/f/nordic-q-a/57549/aes-ecb-decryption-on-nrf52832-with-sdk-14-2Hi All, I am trying to decrypt some data coming in on my board with AES ECB mode. I know that there is no decryption function for ECB and you have to use the same sd_ecb_encrypt function and XOR the resulting ciphertext with the encrypted data.

Note that the ECB peripheral does not do encryption in HW (see <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/ecb.html?cp=4_2_0_27#concept_vnj_kgy_xr">ECB peripheral documentation</a>), but that may not be a problem, depending on how you&nbsp;intend to use it.</p><div style="clear:both;"></div>
