How To Get The Private Key For Digital Signature?
Mar 31, 2007
My web application does user authentication through X.509 digital
certificates in combination with user name and password.
When the user applies for a digital certificate from my certification
authority (CA), I have a VBScript code that generates a public/private
key pair with the RSA algorithm, as well as the certificate signing
request (CSR) in PKCS#10 format. I assume that the key pair should be
maintained by the browser (my application support Internet Explorer
only at this moment). Am I right?
Now, when the user tries to log into his account, I would like to have
my web application receive a digitally signed token from the client.
The token can be the client's username signed with his/her private
key.
Since this signing process will happen on the client side, it can only
be handled by client side script, for example, JavaScript.
But, how do we get access to the private key with JavaScript?

I am by no means a JS programmer, but I like to exhaust all avenues when attacking an issue. A signature fired off on a piece of javascript that came across the wire, with an odd "var unescape" inside of it. I am hoping to throw this code out there, to see if anyone has any insight on what this might be.
I am assuming this is double encoded, but I am not certain. Here is the snippet of code the signature fired off from:
var ibdf=unescape("%u0b0b%u0b0"+"b");
var fdofdopf="xcvb9090";

I have to make a digital clock (which i did figure out) but the number needs to be images with the numbers on them. (ex.: (an image of the number 1+an image of the number 2+image of number 0+images of number8) would be 11:08))
Here's what I have so far. Do I need to use <img src=""> in a function then call the function for my images?

I want to ammend it so that it displays a different color image between 8am and 5pm automatically.

What do you think about emulating private variables for a class this
way?
function Something() {
var private;
Something.prototype.getPrivate = function() { return private; }
Something.prototype.setPrivate = function(newPrivate) { private =
newPrivate; }
}
var some = new Something("My private");
alert(some.getPrivate());
alert(some.setPrivate("Nyah nyah"));
alert(some.getPrivate());
That way the accessor methods instances are shared among instances of
Something. What do you think?

I'm trying to create an extensible class with private members.
Suppose I have the following:
Code:
Obviously, only "y" should be available to instantiations:
Code:
But how can I now extend this class and still access the private properties inside the extension?
Code:
How do I access x there? The someOtherFunction extension is part of the prototype, so it should be in the same scope as someFunction, no?

I want to be able to set a property on a private object by giving the not notation path to the value. The difficulty is that this object is within closure so I can't access it directly to set the value the normal way (eg. dot.notation.path = 'new value'). This seems weird but I can't think of the obvious way.
Example:
// setter function
function set(path, change){
var privateObject = {
a: 'a',
[Code]....

I am using the module pattern and private/public methods. I'm having a problem where the private method is using setTimeout() to call itself recursively, but I can't get the syntax right. Code:

I've got a plugin which is structured as follows:
(function($) {
$.fn.MyFunction = function(o) {
// Here we have some parameters
return this.each(function() {
[Code].....
So what I'm looking for is how to reference MyExternalFunction from my html script. I've tried simply using MyExternalFunction(index) but I get function undefined.

This question applies to javascript generally as opposed to jQuery specifically. I want to be able to structure my scripts into classes, then create them using the "new" keyword, but here is the important bit: How do I make a js function private (or public for that matter)?

I have some confusion about the scripts below:
1) is getRule a local variable or global variable, as it has no var keyword, yet it is an inner function of Validation? So without var, I think global, but being an inner function, I think local. So I'm not sure which.
2) In this line of code: var rule = $.Validation.getRule(types[type]), getRule returns rules, which is just a local variable in Validation. I always see that you return functions, but how does returning a local variable that's just an object literal and not a function be able to return true or false? Now the value of rules is an object literal, and this object returns true or false. So we are basically allowed to use return keyword with local variables that are object literals and not functions?
3) In this line, is foo(age) being called, or is it just being assigned to bar OR is it being called and THEN assigned to bar: var bar = foo(age);
4) Now for the most confusing: age is obviously an object reference as opposed to a literal in the example. Does that make a difference in regards to closures?
Note that I read a number of books, including JavaScript Programmer Reference and Object Oriented JavaScript and jQuery cookbook, which compare primitives vs reference types and how primitive types store directly in memory whereas reference tpyes reference memory, so if one reference changes, they all change where primitive remains ingrained. But when assigning a function as a reference like this, how does that affect the object "age" when passed into bar?
Code:
(function($) {
/*Validation Singleton*/
var Validation = function() {
var rules = {
email : {
check: function(value) {
if(value)
return testPattern(value,".+@.+..+");
return true;
}, .....
$.Validation = new Validation();
})(jQuery);
Code:
function foo(x) {
var tmp = 3;
return function (y) {
alert(x + y + tmp);
x.memb = x.memb ? x.memb + 1 : 1;
alert(x.memb);
}}
var age = new Number(2);
var bar = foo(age); // bar is now a closure referencing age.
bar(10);

I am trying to create a private chat from hacking some opensource chat room.I am trying to use some basic AJAX (noobie) to insert a field into a mysql db.It is doing what I want it to do mysql wise but it also changes the url.
my site runs like this. There is a page called private.php with all the php in. private.php has a switch statement to call other pages (the default is home.php).so if a user say clicks contact the link would be private.php?mode=contact.and then in the private page the switch statement would
case "contact":
require("contact.php");
break;
so the user has searched another user and wants to chat.the url at the moment is private.php?mode=full_profile&id=101 in the full_profile.php page I have the ajax in the head and a submit form to call the ajax function.
here is the ajax code
<script language="javascript" type="text/javascript">
<!--
//Browser Support Code
function ajaxFunction(){
[code]....
now the mysql query runs fine. the problem I have is that when I click the submit the url changes to private.php?x=18&y=28 . (the x and y vales are different everytime I click the submit).can anyone tell me where the x and y values are coming from and also why the ajax function is changing the url as the whole point of using ajax is to avoid that.

I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

I'm trying to do something, but I don't know if it's possible.
Basically, I want to have a public static class method that could
access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing
something like
function method(param) {
param.privateMethodOfClass();
}
I've done a lot research and experimentations but just can't come up
with a solution... I don't even know if what I'm trying to do is
possible.
