New subject: Query related to ARM - MbedTLS

9 Sep 2020


      Hi,
Unrelated comment from my side, adding on to Manuel's comment:
It appears that ST supplies a binary blob which does make use of their
hardware crypto accelerator.

Cheers,

Hi,
On those CPUs, the AES implementation in Mbed TLS is pure C, it doesn't use any hand-written assembly. The only platforms where it does so so far are x86-64 (to take advantage of the AES-NI extension if available), and some Via CPUs (x86) that have AES acceleration as well.
Regards,
Manuel.

Subject: [mbed-tls] Query related to ARM - MbedTLS
Hi,
I hope you are doing well. I am using the mbedTLS AES library in my projects, part of my master thesis at Uppsala University.
I would like to know whether the mbedTLS AES library uses any assemble specific code for operations? I am using this library on Cortex-M23 and Cortex M0+.
Looking forward to hearing from you.
Best regards,
Hafiz Areeb Asad
