Function Documentation

void sha4	(	unsigned char *	input,
		int	ilen,
		unsigned char	output[64],
		int	is384
	)

Output = SHA-512( input buffer ).

Parameters:

	input	buffer holding the data
	ilen	length of the input data
	output	SHA-384/512 checksum result
	is384	0 = use SHA512, 1 = use SHA384

int sha4_file	(	char *	path,
		unsigned char	output[64],
		int	is384
	)

Output = SHA-512( file contents ).

Parameters:

	path	input file name
	output	SHA-384/512 checksum result
	is384	0 = use SHA512, 1 = use SHA384

Returns:

0 if successful, 1 if fopen failed, or 2 if fread failed

void sha4_finish	(	sha4_context *	ctx,
		unsigned char	output[64]
	)

	)

Output = HMAC-SHA-512( hmac key, input buffer ).

Parameters:

	key	HMAC secret key
	keylen	length of the HMAC key
	input	buffer holding the data
	ilen	length of the input data
	output	HMAC-SHA-384/512 result
	is384	0 = use SHA512, 1 = use SHA384

void sha4_hmac_finish	(	sha4_context *	ctx,
		unsigned char	output[64]
	)
