Hi Alan,

[quote user="ekidsalan123"]As mentioned, I have successfully executed sample code on the previous nRF5 SDK, and since PCA10040 is the official development board from Nordic, I assume that AES cryptography should be supported on the nRF52832, correct?[/quote]

This is correct. I was referring previously to the sample support in NCS. This means that the sample is not fully tested to be working on nrf52832, but it might work with some additional configuration. Documentation lists nrf52832 as supported for PSA Crypto. You can look at this discussion to get some idea what might be missing.

Best regards,
Dejan

Hi Dejan,

Thank you for the information. What I need to understand is whether AES encryption and decryption are possible on the nRF52832 using the nRF Connect SDK.

As mentioned, I have successfully executed sample code on the previous nRF5 SDK, and since PCA10040 is the official development board from Nordic, I assume that AES cryptography should be supported on the nRF52832, correct?

This is the sample code directory that I have successfully executed with my nRF52832 boarad.

Hi Alan,

If you look at each of the crypto samples, you can see that there is no support for nrf52832 in any of them. You would need to have at least nrf52840, except for SHA-256 sample which can also be used on nrf52833.

Best regards,
Dejan

Hi Dejan,

In the old version of SDK, I found that AES smaple can operate normally on nRF52832. Is there any related smaple expected to be released in the new version of SDK?

This smaple code I found in nRF5 SDK.

nRF5_SDK_17.1.0_ddde560\examples\crypto\nrf_crypto\aes\aes_cbc_with_padding

Best regards,

Hi,

Based on the requirements, the sample AES CBC is not supported on nRF52832.

Best regards,
