Random "Pronouncable" Password Generator

After looking at this password generator (http://www.javascriptkit.com/script/script2/passwordgenerate.shtml) and thinking "how on earth do i remember that" i thought it would be easier to remember something that is "sayable".

this script lists the basic elements of a word and chooses a random word structure to make the word pronouncable... or... at least 50% of them ;). I'm sure there is a way to do this to cut down on the code... but here goes anyway...


<script>

/****************************************

* Random "Pronouncable" Password Script *

****************************************/

var letters = "bcdfghjklmnprstvwxyz";
var vowels = "aeiou";

groups = new Array();
groups[0]="th";
groups[1]="ch";
groups[2]="sh";
// groups[3]="qu";

function generate(number) {

// randomize letters

var vowel1 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group1 = groups[Math.floor(Math.random()*groups.length)];
var letter1 = letters.charAt(Math.floor(Math.random()*letters.length));
var vowel2 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group2 = groups[Math.floor(Math.random()*groups.length)];
var letter2 = letters.charAt(Math.floor(Math.random()*letters.length));
var vowel3 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group3 = groups[Math.floor(Math.random()*groups.length)];
var letter3 = letters.charAt(Math.floor(Math.random()*letters.length));
var vowel4 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group4 = groups[Math.floor(Math.random()*groups.length)];
var letter4 = letters.charAt(Math.floor(Math.random()*letters.length));

// specify the structure of the words (in order for them to be pronouncable)
// feel free to add your own...

structure = new Array();
structure[0]=letter1+vowel1+letter2+letter3+vowel2+letter4+vowel3+group1;
structure[1]=group1+vowel1+letter1+letter2+vowel2+letter3;
structure[2]=group1+vowel1+letter1+letter2+vowel2+group2;
structure[3]=group1+vowel1+letter1+vowel2+"s";
structure[4]=vowel1+group1+vowel2+letter1+vowel3;
structure[5]=group1+vowel1+letter1+vowel2+group2;
structure[6]=vowel1+group1+vowel2+letter1;

var password=structure[Math.floor(Math.random()*structure.length)];

if (number==1) {
document.passform.passbox.value=password+Math.floor(Math.random()*100)
}
else {
document.passform.passbox.value=password;
}
}
window.onload=generate
</script>

or you could see a working demo (http://www.btinternet.com/~chriscaws/password2.html).

Okay... so not all of the words are sayable... and none of them make sense... but even if you dont use it as a password generator... you could have hours of fun trying to say them :D

any ideas / improvements / shortenings will be appreciated :thumbsup:

I have seen a variant of this which generates much more "pronouncable" passwords of eight characters -

consonant - vowel - consonant - vowel - consonant - vowel - consonant - vowel

e.g. votohubo tofesuma redahedu

As each syllable represents 20 x 5 = 100 numbers, an eight-letter
password is 1 of 100 million (10 to the fourth) possibles.

not hard. i made it so you could add your own structures... you could just add in this....

structure[7]=letter1+vowel1+letter2+vowel2+letter3+vowel3+letter4+vowel4

If anyone wants to see what it looks like without logging in to that yahoo thing, goto www.7324.tk (http://www.7324.tk) I just pasted the code in there so you can see it. it's good, but I would reccomend...


<script language="javascript" type="text/javascript">
function randomString() {
var chars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
var string_length = 10;
var randomstring = '';
for (var i=0; i<string_length; i++) {
var rnum = Math.floor(Math.random() * chars.length);
randomstring += chars.substring(rnum,rnum+1);
}
document.randform.randomfield.value = randomstring;
}
</script>
<form name="randform">
<input type="button" value="Randomize!" onClick="randomString();">&nbsp;
<input type="text" name="randomfield" value="NO-NAME!">
</form>

nice.. but i dont think that 8vn is pronouceble. i would remove the numbers.
with a little more testing, this would be awesome.

who are you saying that to? me or him?
if you want to remove the numbers, just take them out in your script...
