sha224Digest()

int sha224Digest	(	sha224Param *	sp,
		byte *	digest
	)

This function finishes the current hash computation and copies the digest value into digest.

Parameters

sp	The hash function's parameter block.
digest	The place to store the 32-byte digest.

Return values

0	on success.

sha224Process()

void sha224Process

(

sha224Param *

sp

)

sha224Reset()

int sha224Reset

(

sha224Param *

sp

)

This function resets the parameter block so that it's ready for a new hash.

Parameters

sp	The hash function's parameter block.

Return values

0	on success.

sha224Update()

int sha224Update	(	sha224Param *	sp,
		const byte *	data,
		size_t	size
	)

This function should be used to pass successive blocks of data to be hashed.

Parameters

sp	The hash function's parameter block.
data
size
