| Question : | How can I create random passwords? | |
| | Answer : |
<?
function Random_Password($length) {
srand(date("s"));
$possible_charactors = "abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ";
$string = "";
while(strlen($string)<$length) {
$string .= substr($possible_charactors, rand()%(strlen($possible_charactors))),1);
}
return($string);
}
echo Random_Password(8);
?>
A good Random Pronounceable Password Generator can be done like this (http://www.zend.com/codex.php?id=215&single=1):
<?
function genpassword($length){
srand((double)microtime()*1000000);
$vowels = array("a", "e", "i", "o", "u");
$cons = array("b", "c", "d", "g", "h", "j", "k", "l", "m", "n", "p", "r", "s", "t", "u", "v", "w", "tr",
"cr", "br", "fr", "th", "dr", "ch", "ph", "wr", "st", "sp", "sw", "pr", "sl", "cl");
$num_vowels = count($vowels);
$num_cons = count($cons);
for($i = 0; $i < $length; $i++){
$password .= $cons[rand(0, $num_cons - 1)] . $vowels[rand(0, $num_vowels - 1)];
}
return substr($password, 0, $length);
}
?>
examples:
include("genpassword.function")
echo genpassword(10);
makes a password on 10 chars
