AES 256 bit keys with CC310 cryptocellhttps://devzone.nordicsemi.com/f/nordic-q-a/43980/aes-256-bit-keys-with-cc310-cryptocellThe AES tests for the CC310 cryptocell backend seem to only use the 128 bit key length. While ECDF seems to support bigger key sizes (192, 256) AES does not. Is this a hardware limitation of the CC310 CryptoCell? Is it possible to use 256bit keyen-USTelligent Community 13Sun, 24 Feb 2019 21:23:35 GMTRE: AES 256 bit keys with CC310 cryptocellhttps://devzone.nordicsemi.com/thread/172651?ContentTypeID=1Sun, 24 Feb 2019 21:23:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:88910848-8eed-484d-80c8-9bb786fe6eb0Jakub Rzeszutko<p>It is software.</p><div style="clear:both;"></div>RE: AES 256 bit keys with CC310 cryptocellhttps://devzone.nordicsemi.com/thread/172641?ContentTypeID=1Sun, 24 Feb 2019 11:23:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:08449955-10a0-414b-bae6-2bb9058bfaf9dvescovi<p>is the mbdetls backend hardware acceleerated?
