Creating all key combinations passwords

["Lasitha Alawatta" <Lasitha.A@xxxxxxxx>]

 

Hi All,

 

 

I’m going to create all key combinations; simple-letter passwords and store those in to MySql DB.

Using = a-z (simple letters)

Password length = 6

Number of possibilities = 26 x 26 x 26 x 26 x 26 x 26 = 308,915,776

 

This is my code:

 

<?php

 

      for($i=0;$i< 500000000;$i++){

            $arrPwd[] = createPwd();

      }

 

      $arrUniqueData = array_unique($arrPwd);

 

      foreach($arrUniqueData as $key=>$val){

            // Inserting to DB

}

      function createPwd() {

            $lower = "abcdefghijklmnopqrstuvwxyz";

            $seed_length += 26;

            $seed .= $lower;

           

            for($x=1;$x<=6;$x++){

                  $ strPwd.= $seed{rand(0,$seed_length-1)};

            }

            return($strPwd);

      }

?>

 

What is the easiest way to get my output?

 

1. Because above code will stuck the PC (for($i=0;$i< 500000000;$i++){).
2. I use 500000000 instead of 308915776, because createPwd() function will duplicating the password.

 

Suggesting, comments, code samples are highly appreciate.

 

Thanks in advance,

Lasitha.
