nrf52832 hardware ECB decryption(AES)

[john.liu]

I use SDK15.0

 I found nrf_ecb_init(),nrf_ecb_set_key() and nrf_ecb_crypt(),this is an encryption. I didn't find the decryption of nrf52832.

nrf52832 support AES ECB encryption,but not support decryption of nrf52832?What should I do to decrypt? Thanks!

Hi,

Try using nrf_crypto library:

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_crypto.html?cp=4_0_1_3_11

AES description is here:

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_crypto_aes.html?cp=4_0_1_3_11_15_0

While you are using nrf52832 you are interested in mbedtls backend.

Examples can be found here:

examples\crypto\nrf_crypto\aes

Hi,

Thank you so much for supporting,but ECB was not found in examples\crypto\nrf_crypto\aes.

Hi,

ECB mode is included in the nrf_crypto\aes\aes_all_cli example.
