Referenced by main().

int sha1_file	(	char *	path,
		unsigned char	output[20]
	)

Output = SHA-1( file contents ).

Parameters:

	path	input file name
	output	SHA-1 checksum result

Returns:

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

Referenced by main(), and sha1_wrapper().

void sha1_finish	(	sha1_context *	ctx,
