PHP Random Pass Generator Script
« on: January 09, 2009, 10:35:03 pm »
I've enhanced my script a bit and included the "form" that you all are asking for. I also added a built-in error handling system and options to use numbers, upper case letters, lower case letters, and symbols.

Code: [Select]
<?php
// Password Generator v1.2
// Created by ccbtimewiz (ccbtimewiz@jeunosky.net)

$limit = 100;
function generate_pass()
 {
 global $limit;

 $pass = '';
 $length = '';
 $nums = array();
 $caps = array();
 $lowers = array();
 $symbols = array();

 if ($_REQUEST['usenums'])
 $nums = range('0', '9');

 if ($_REQUEST['usecaps'])
 $caps = range('A', 'Z');

 if ($_REQUEST['uselower'])
 $lowers = range('a', 'z');

 if ($_REQUEST['usesymbols'])
 $symbols =  array_merge(range("{", "~"), range(":", "@"));

 $chars = array();

 if (!empty($nums) )
  {
 foreach ($nums as $value)
 $chars[] = $value;
  }

 if (!empty($caps) )
  {
 foreach ($caps as $value)
 $chars[] = $value;
  }

 if (!empty($lowers) )
  {
 foreach ($lowers as $value)
 $chars[] = $value;
  }

 if (!empty($symbols) )
  {
 foreach ($symbols as $value)
 $chars[] = $value;
  }

 if (empty($chars))
 $chars = array_merge(array_merge(range('a', 'z'), range('A', 'Z')), range('0', '9'));

 $count = count($chars);

 if( is_numeric($_REQUEST['value']) && (abs($_REQUEST['value']) < $limit) && (!empty($_REQUEST['value'])) )
 $length = abs((int) $_REQUEST['value']);
 elseif (empty($_REQUEST['value']) && ($_REQUEST['value'] != '0') && !isset($_REQUEST['value']))
 $length = 'keepalive';
 else
 show_error();

 mt_srand((double)microtime() * 1000000);

 if ($length != 'keepalive')
  {
 for($i = 0; $i < $length; $i++)
 $pass .= $chars[mt_rand(0, $count - 1)];
  }

 if (!empty($pass))
 echo "Your password is:<br /><tt><strong>$pass</strong></tt>";
 }

function show_error()
 {
 global $limit;

 if ($limit <= abs($_REQUEST['value']))
 $error = "
<strong>The following errors were processed during your request:</strong>
<br />
<em>&bull; Length input is over or equal to $limit characters.</em>";
 elseif( !is_numeric($_REQUEST['value']) && (!in_array($_REQUEST['value'], array('', '0', 'keepalive'))) )
 $error = "
<strong>The following errors were processed during your request:</strong>
<br />
<em>&bull; Length input contained non-numerical characters.</em>";
 elseif ($_REQUEST['value'] == '0')
 $error = "
<strong>The following errors were processed during your request:</strong>
<br />
<em>&bull; Length input was submitted as 0.</em>";
 elseif (empty($_REQUEST['value']))
 $error = "
<strong>The following errors were processed during your request:</strong>
<br />
<em>&bull; Length input was left empty.</em>";
 else

A random password. Eg, a pass you could use for something if you can't think of anything good.

I've completely revamped the script to be more "user friendly" and feature-esque. View the first post to see the updates.
