A user friendly, strong password generator PHP function.
<?PHP
// Generates a strong password of N length containing at least one lower case letter,
// one uppercase letter, one digit, and one special character. The remaining characters
// in the password are chosen at random from those four sets.
//
// The available characters in each set are user friendly - there are no ambiguous
// characters such as i, l, 1, o, 0, etc. This, coupled with the $add_dashes option,
// makes it much easier for users to manually type or speak their passwords.
//
// Note: the $add_dashes option will increase the length of the password by
// floor(sqrt(N)) characters.
function generateStrongPassword($length = 9, $add_dashes = false, $available_sets = 'luds')
{
$sets = array();
if(strpos($available_sets, 'l') !== false)
$sets[] = 'abcdefghjkmnpqrstuvwxyz';
if(strpos($available_sets, 'u') !== false)
$sets[] = 'ABCDEFGHJKMNPQRSTUVWXYZ';
if(strpos($available_sets, 'd') !== false)
$sets[] = '23456789';
if(strpos($available_sets, 's') !== false)
$sets[] = '!@#$%&*?';
$all = '';
$password = '';
foreach($sets as $set)
{
$password .= $set[array_rand(str_split($set))];
$all .= $set;
}
$all = str_split($all);
for($i = 0; $i < $length - count($sets); $i++)
$password .= $all[array_rand($all)];
$password = str_shuffle($password);
if(!$add_dashes)
return $password;
$dash_len = floor(sqrt($length));
$dash_str = '';
while(strlen($password) > $dash_len)
{
$dash_str .= substr($password, 0, $dash_len) . '-';
$password = substr($password, $dash_len);
}
$dash_str .= $password;
return $dash_str;
}
