[AEDELGOD]

Hey all, I've been re-developing a cracker for my site, and when i enter the hash to crack it displays the results 3 times.

 

Example:

Here's my source:

{

    return crypt($word, "sl");

}

function undes($word, $hash)

Your words array probably has duplicates.

 

Try this:

 

$words = array_unique(file("wordlist.txt"));
