php to generate 13 character password

[kaliok]

I am having some trouble protecting a folder of movie files.I am using htaccess and htpasswd  to do this. I need to have the ability to add additional users to the list, but I need to give the admin person the ability to do this. The method I thought I could use was to have a php script that would take the new username and password that are entered and then write that to the htpasswd file. I have not been able to locate a php script that generates a 13 character password. There are several places I have found that have a form to generate these types of passwords but I would like the php to do this for me.

$pwFile = "../private/.htpasswd";
$fh = fopen($pwFile, 'a') or die("can't open file");
$rawpassword = ($enteredpassword);
$password = crypt($rawpassword); 
$myNewCombo = "$UserName:$password";
fwrite($fh, $myNewCombo);
fclose($fh);

 

The above code generates a password that is too long, I am guessing it is something I am doing wrong with crypt, perhaps it is the wrong function to use. Any help advice is much appreciated.

looks like the Standard DES call with crypt would give you the 13 digits you are looking for.

Ahh. OK DES... that's what I was looking for...didn't know what it was called. Thanks.. I think I may have got it working.
