This is a small script written in PHP which will help you to generate N passwords of N length in less than 1ms 😛
Make sure you have PHP installed, then copy this code to a file called randompass.php
#!/usr/bin/php -q
<?
// no i,l,o keep passwords easy
$chars = "abcdefghjkmnpqrstuvwxyz0123456789";
$passlen = (intval($argv[1])? intval($argv[1]):6);
$passnum = (intval($argv[2])? intval($argv[2]):1);
echo "Generating $passnum passwords of $passlen letters/numbers\n";
// feed the random God :P
srand(((int)((double)microtime()*1000003)));
for ($i=1;$i<=$passnum;$i++) _gen_pass();
function _gen_pass() {
global $chars, $passlen;
$cnt = 1;
while ($cnt <= $passlen) {
$myrand = rand() % 33;
$tmp = substr($chars, $myrand, 1);
if (rand(0,1)) $tmp = strtoupper($tmp);
$pass = $pass . $tmp;
$cnt++;
}
echo $pass . "\n";
}
?>
Now you have the file don’t forget to make it executable:
chmod +x randompass.php
How it works? See some examples:
Usage: ./randompass.php [password_length] [password_number]
# The default execution will drop 1 password of 6 letters/numbers
./randompass.php
Generating 1 passwords of 6 letters/numbers
9hBEq1
# want 5 passwords of 12 letters/numbers ?
./randompass.php 12 5
Generating 5 passwords of 12 letters/numbers

That’s all, use it for what you need, don’t try to break it or find stupid bugs 😛
