MATH_SHA1Init

Syntax

#include <nitro/math/dgt.h>

static inline void MATH_SHA1Init( MATHSHA1Context *context );

Arguments

context

Pointer to the context structure to initialize. This structure is used for SHA-1 generation.

Return Values

None.

Description

This function initializes the MATHSHA1Context-type context structure used in calculating SHA-1. Make sure that this function is called before using the MATH_SHA1Update and MATH_SHA1GetHash 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-1 is an algorithm to find the message digest value. For details, see RFC (Request For Comments) 3174, which is published by IETF (The Internet Engineering Task Force).
