What does enabling hardware AES in sdkconfig do?

[jsam589]

I have a working IoT Azure device and was looking at the sdkconfig.defaults settings.
There is a good bit of MBEDTLS action happening, for certificates and keys, but the following config parameter does not seem to make a difference to whether the software works or not.

Can anyone explain what is the difference of setting this to 'n', rather than allowing the default of 'y'?

CONFIG_MBEDTLS_HARDWARE_AES=y

Thanks!

It switches between doing the AES encryption in hardware and doing it in software. Both solutions work, but there may be some performance differences between the two, depending on how you use the ESP32.

I think you will do nothing right now, because it did not support aes hw acceleration for now, based on post viewtopic.php?f=10&p=56361

Note that that list is for the ESP32-S2.
