MBEDTLS IMPLEMENTATION HAL SHA256 TYPES ¶

group MBEDTLS_IMPLEMENTATION_HAL_SHA256_TYPES

This file contains SHA-224 and SHA-256 definitions and functions based on STM32 HASH hardware crypto accelerator.

The Secure Hash Algorithms 224 and 256 (SHA-224 and SHA-256) cryptographic hash functions are defined in FIPS 180-4: Secure Hash Standard (SHS) .

SHA-256 context structure.

The structure is used both for SHA-256 and for SHA-224 checksum calculations. The choice between these two is made in the call to mbedtls_sha256_starts_ret().
