int	sha256Reset (sha256Param *sp)
	This function resets the parameter block so that it's ready for a new hash.
int	sha256Update (sha256Param *sp, const byte *data, size_t size)
	This function should be used to pass successive blocks of data to be hashed.
int	sha256Digest (sha256Param *sp, byte *digest)
	This function finishes the current hash computation and copies the digest value into digest.

int sha256Digest (  sha256Param *  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.

void sha256Process (  sha256Param *  sp  )

This function performs the core of the SHA-256 hash algorithm; it processes a block of 64 bytes. Parameters: sp  The hash function's parameter block.

int sha256Reset (  sha256Param *  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.

int sha256Update (  sha256Param *  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  Return values: 0  on success.
