void sha2	(	const unsigned char *	input,
		size_t	ilen,
		unsigned char	output[32],
		int	is224
	)

Output = SHA-256( input buffer )

Parameters:

input	buffer holding the data
ilen	length of the input data
output	SHA-224/256 checksum result
is224	0 = use SHA256, 1 = use SHA224

int sha2_file	(	const char *	path,
		unsigned char	output[32],
		int	is224
	)

Output = SHA-256( file contents )

Parameters:

path	input file name
output	SHA-224/256 checksum result
is224	0 = use SHA256, 1 = use SHA224

Returns:

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