Hi, i am a newbie in programming. Please how can i change this mhash code 		
	
		
 to hash code. This code is from the function.php file in the liberty reserve mass payment tool. Presently, on my server if i want to make use of the tool it gives me this error.. Fatal error: Call to undefined function mhash() in /home/dollarsc/public_html/includes/LibertyReserve/functions.php on line 117. 
Please kindly help me. I think the solution is to change the mhash variables to hash variables. If you feel you know any other solution, please post it here. Thanks

$sha256 = bin2hex(mhash(MHASH_SHA256, $authString));

	$sha256 = bin2hex(mhash(MHASH_SHA256, $authString));
return strtoupper($sha256);
}
