MBEDTLS IMPLEMENTATION STCRYPTOLIB SHA512 ALT FUNCTIONS

group MBEDTLS_IMPLEMENTATION_STCRYPTOLIB_SHA512_ALT_FUNCTIONS

Public API functions for STCRYPTOLIB SHA512 alternate implementation.

FIPS-180-2 compliant SHA-512 implementation

This file implements SHA512 based on STM32 crypto library.

The SHA-512 Secure Hash Standard was published by NIST in 2002.

MBEDTLS IMPLEMENTATION STCRYPTOLIB SHA512 ALT TYPES

group MBEDTLS_IMPLEMENTATION_STCRYPTOLIB_SHA512_ALT_TYPES

This file contains SHA-384 and SHA-512 definitions and functions based on STM32 crypto library.

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().
