<script language="php">

function passgen($len)
{
$pass = "";

if($len > 5 && $len < 17)
{
srand((double) microtime() * 1000000);
for($i=0;$i<12;$i++)
{
$pass .= chr(rand(0,255));
}
$pass = substr(base64_encode($pass), 0, $len);
}
return $pass;
}

</script>

<!--
Function passgen (above) creates a random password suitable for any use. The
generated passwords are pure junk - using mixed alpha, numeric and a few symbols.

Usage:

passgen(int password_length);

Password length can be anything from 6 to 16 characters. Other length values
result in an empty string being returned.

Method:

Quite simple. A string of 12 random 8 bit characters is built up in a loop. The
resulting random 12 bytes of data are then UU-Encoded which provides a 16
character string of mixed case, numerics and a few symbols. This is then
shortened to the length requested in the parameter passed to passgen to return
a random password of the requires length.

Example usage below (you can just chuck this on a server to see what it does).
Strip out the function above to use it in your own code.
