Whirlpool Encryption

[CourtezBoi]

So I have created a website in PHP which includes a blog. The website has an account system, and I am now trying to create a desktop application in java which will allow me to login and post into the blog.

The problem I have is with the encryption. The website uses a whirlpool hash and encryption, and I can't figure out how to duplicate the same in java. I have found a code on the internet which seems to have the functionality of creating the whirlpool hash, but I don't know which method to use to actually send it the password string and get back the hash.

Here is the PHP code that runs on my website:

PHP Code:

    function getPasswordSalt()
    {
        return substr( str_pad( dechex( mt_rand() ), 8, '0', STR_PAD_LEFT ), -8 );
    }

    function getPasswordHash( $salt, $password )
    {
        return $salt . ( hash( 'whirlpool', $salt . $password ) );
    }

    function comparePassword( $password, $hash )
    {
        $salt = substr( $hash, 0, 8 );
        return $hash == $this->getPasswordHash( $salt, $password );
    } 


The above functions are used in the following manner:

PHP Code:

getPasswordHash( $this->getPasswordSalt (), $password ); 


And here is a link to the java code that I found:

If anyone has any suggestions to solve the problem it'd be greatly appreciated!

Well, according to the tests in here:

PHP Code:

Whirlpool w = new Whirlpool();
byte[] digest = new byte[Whirlpool.DIGESTBITS];
w.NESSIEinit();
w.NESSIEadd("whirpool this.");
w.NESSIEfinialize(digest); 


I haven't a clue why the display method is private, but you can look at that to print a readable string if you need it for whatever reason.
