nRF52832 libraries for AES

[Sai Kiran]

Hi

I am working on cryptography algorithms. I am trying to write my own implementation of main function. Inside the main function, I wish to call AES functions. I want AES functionality in ".a" format. How do I get ".a" file for AES functions? Is there any method for compiling and getting ".a" files? Or is ".a" file already present in the SDK? If it's there, may I know where it is there and how to use in my main code?

Thanks in advance.

The AES peripherial is restricted - so there are softdevice functuions for AES usage.

Look at sd_ecb_block_encrypt () and sd_ecb_blocks_encrypt() documentation (infocenter, softdevice API docs).

The AES peripherial can only do aes block encrypt (as used in bluetooth) - everything else must be done in software on a nRF52832.
