MBEDTLS IMPLEMENTATION HAL SHA512 TYPES

group MBEDTLS_IMPLEMENTATION_HAL_SHA512_TYPES

This file contains SHA-384 and SHA-512 definitions and functions based on STM32 HASH hardware crypto accelerator.

The Secure Hash Algorithms 384 and 512 (SHA-384 and SHA-512) cryptographic hash functions are defined in FIPS 180-4: Secure Hash Standard (SHS) .

struct mbedtls_sha512_context

#include <hal_sha512_alt.h>

SHA-512 context structure.

            The structure is used both for SHA-512 and for SHA-384
            checksum calculations. The choice between these two is
            made in the call to mbedtls_sha512_starts_ret().
