nrf5340 NCS 2.8 RSA 2048 example

[giun.kim]

I am developing with the nRF5340 using NCS version 2.8 and want to test RSA 2048-bit encryption. However, there is only an example for 4096-bit encryption. Could you explain how to perform 2048-bit encryption?

Hi,

Thanks for reaching us for your questions.

Make the following change in v2.8.0\nrf\samples\crypto\rsa\prj.conf and change all 4096 to 2048 in v2.8.0\nrf\samples\crypto\rsa\src\main.c should work.

CONFIG_PSA_WANT_RSA_KEY_SIZE_4096=n

CONFIG_PSA_WANT_RSA_KEY_SIZE_2048=y

Best regards,

Charlie
