Why go nuts and use somebody's service when it's so easy to stick one
in there via javascript? Making psuedorandom numbers ain't hard.

<script type="text/javascript">
function generatePassword(length) {
    var password = "";
    for (i=0; i < length; i++) {
        num = (parseInt(Math.random() * 1000) % 94) + 33;
        while (checkPunc(num)) { num = (parseInt(Math.random() * 1000)
% 94) + 33; }
        password = password + String.fromCharCode(num);
    }
    return password;
}

function checkPunc(num) {
    if ((num >=33) && (num <=47)) { return true; }
    if ((num >=58) && (num <=64)) { return true; }
    if ((num >=91) && (num <=96)) { return true; }
    if ((num >=123) && (num <=126)) { return true; }
    return false;
}
</script>
