More specifically we are interested in the AES256-GCM algorithm on STM32F777.
Looking at the User Manual (http://www.st.com/content/ccc/resource/technical/document/user_manual/group0/f9/6e/f2/a2/b4/ec/49/c0/DM00215061/files/DM… ) I conclude that for the STM32F756 the crypto hardware is used when using the STM32AccHwCryptoV3.1.0_Xy_C_O.a library.
However, if I look at the actual software (library and headers) I get confused:
The STM32_Crypto library (not HW accelerated) has a Inc/AES/GCM/aes_gcm.h header.
The STM32_Crypto_AccHw variant does not include any header for GCM but Inc/AES/AccHw_aes.h contains the following:
A header with this filename does not ship with the libraries.
Does anyone have experience with AES-GCM on a STM32 with crypto accelerator?
