Monkey on a Keyboard

my online scrapbook of scrambled thoughts

I've been trying to make my own hashing function for this blog, with no luck at all. So, I try to find the latest hashing function which known to be super secure, and I encounter "whirlpool". This hashing function is and never will be patented, so it's free to use. In addition to the randomized multilevel encryption process which I have been adding since the early development of this blog, I add the whirlpool function to the mix.

Here's my multilevel encryption process which contain the whirlpool algorithm:

$password=$encrypted;
//the $encrypted var comes from my hand made encryption algorithm

$formation=hash("whirlpool", $password);
$array=array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l",
	"m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z");

$formation=str_replace($array, "", $formation);
$i=0;
$sementara="";
while($formation[$i] || $formation[$i]=="0")
{
	$a=decbin($formation[$i]);
	while(strlen($a)<4)
	{
		$a="0".$a;
	}
	$sementara=$sementara.$a;
	$i=$i+1;
}
$formation=$sementara;
$encrypted_password=$password;
$i=0;
while ($formation[$i] || $formation[$i]=="0")
{
	if (intval($formation[$i])==0)
	{
		$encrypted_password=md5($encrypted_password).sha1($encrypted_password);
		$encrypted_password=hash("whirlpool", $encrypted_password);
	}
	else if (intval($formation[$i])==1)
	{
		$encrypted_password=sha1($encrypted_password).md5($encrypted_password);
		$encrypted_password=hash("whirlpool", $encrypted_password);
	}
	$i=$i+1;
}

As you can see, in each level of the encryption process, there's 3 different hash functions to be executed (md5, sha1, and whirlpool). An average password will have at least 300 level of encryption. So a password cracker will have to go through at least 900 hash function executions to brute force the password, and that's only for one word. Even a super computer will be exhausted to crack it.
