https://devzone.nordicsemi.com/f/nordic-q-a/118588/aes-128-cmacHey , I want to implement a CMAC with the AES algorithm . In the prj.conf i added CONFIG_PSA_WANT_ALG_CMAC =y but i received this error : error: #error &quot;PSA_WANT_ALG_CMAC defined, but not all prerequisites&quot; i would like to know , which prerequisitesen-USTelligent Community 13Tue, 04 Feb 2025 12:10:05 GMThttps://devzone.nordicsemi.com/thread/521294?ContentTypeID=1Tue, 04 Feb 2025 12:10:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:40eedc47-0b52-4512-a74e-3fab4868abdbSimonr<p>Hi</p> <p>The prerequisites you&#39;re missing seems to be either one or both of the following. Please try enabling these configs and see if that makes a difference:&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/kconfig/index.html#CONFIG_PSA_WANT_KEY_TYPE_AES">PSA_WANT_KEY_TYPE_AES </a>and&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/kconfig/index.html#CONFIG_PSA_WANT_ALG_ECB_NO_PADDING">PSA_WANT_ALG_ECB_NO_PADDING</a></p> <p>Potentially, by setting <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/kconfig/index.html#CONFIG_PSA_CRYPTO_ENABLE_ALL">CONFIG_PSA_CRYPTO_ENABLE_ALL</a>&nbsp;to enable all PSA crypto features should set both of these to y by default.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
