Hmac in MIGS payment in php and Node.js different

Question

I'm trying to convert the MIGS payment gateway code from PHP to NODE.js
Everything else is fine except this hmac hash code generation
PHP CODE

strtoupper(hash_hmac('SHA256',$this->hashInput, pack("H*",$this->secureHashSecret)));

Javascript/NODE.js code

var binKey = new Buffer(SecureSecret,"hex");

var hasheddata = new Buffer(    
    crypto.createHmac('SHA256',binKey).update(hashvalue).digest('hex')                            
).toString().toUpperCase();   

hashInput and securesecret is same for both the above code , but i'm always getting different values .

Answer 1

Sorry i messed up the Order of Hashvalue .. The code is working fine
So if anyone want to convert the same here it is.. Enjoy
