MATH_SHA256Init

Syntax

#include <nitro/math/dgt.h>

static inline void MATH_SHA256Init( MATHSHA256Context *context );

Arguments

context Pointer to the context structure to initialize. This structure is used for SHA-256 generation.

Return Values

None.

Description

This function initializes the MATHSHA256Context context structure used for SHA-256 calculations. Make sure that this function is called before using the MATH_SHA256Update and MATH_SHA256GetHash functions.
You can re-apply this function to a context structure that is already initialized. In this case, it will return the context structure to its initial state. SHA-256 is an algorithm to find the message digest value. For details, refer to the Federal Information Processing Standard, FIPS PUB 180-2.
