Using Php To Encrypt Data On The Server And Decrypt Data On Client?
I am building a simple training website using php. I want to share my training material without fear of copyright infringement. I want to send encrypted documents from the server and decrypt them (on the user's machine using javascript - which means he can peek into it) and displays it. This way, the user doesn't simply get the document but needs to decrypt it.

Writing And Reading Cookies - Save / Recall?
I've looked on several websites and several threads here regarding writing and reading cookies with javascript, and I just can't seem to get it to work. All I want is a simple text box with 2 buttons: Save and Recall. Text entered into box is saved to a cookie when "Save" is pressed, and at a later date when "Recall" is pressed the saved text will show up in the box.

Encrypt (AES) And Decrypt In .NET?
I encrypted(AES) data with Javascript . I want to decrypt this in c#. While decrypting in c3 I am getting error "length of the data to be decrypt is not valid" For encryption in Javascript I am using following code,

var encByteData = byteArrayToHex(rijndaelEncrypt(strFileContent, hex2s(randomnumber), "CBC"));

For the decryption in c# I am using following code,

Calling function,

DecryptData(byteArraySignData, "91860F52E5C3A09BA3B827F28070E08D",
ref byteArrayDecryptedData);

SSL Alternative - Encrypt Password With - Submit To PHP To Decrypt
I'm building a website and my payment methods will be Google Checkout and Paypal. There will be links/buttons which will redirect the user to the secure Google/Paypal sites for processing the payments. This means I do not need the $150/year added expense and complexity of installing SSL certificates for my site.

However I would like to encrypt user's passwords as they are logging in so that if they are on a network some malicious person running FireSheep etc can't read the user's actual password as it is being sent to the server. The rest of the site doesn't need encryption as it's not really sensitive data and would probably slow the user experience down significantly.

My thoughts are this could be implemented with public key cryptography. Lets say the process goes something like this:

Public key is in the JavaScript external file, private key in PHP on the server User enters their username and password into the form and clicks submit The JavaScript runs and encrypts the password, storing it back in the text field Form is submitted to server and the password is decrypted with PHP Plain text password in PHP is salted & hashed then compared to hash in database. Possible similar process for the registration/change password functions.

I'm thinking something like RSA would do the trick. But I've hunted around the net for a working JavaScript library to do it but none seem to be compatible with the PHP libraries available. At any rate it needs to generate a set of keys that are compatible with the JavaScript and PHP.

Anyone know of an actual working solution for this? If not how about we write one then open source it. Unfortunately writing encryption/decryption code is pretty complex so I don't really know exactly what the existing libraries are doing and how to modify them to make it work. I already have protection for session fixation/hijacking so I'm not interested in that. Just interested in encrypting the data before it gets to the web server.

Reading/Writing Data From A Win7 Gadget XML?
I am trying to teach myself a little bit about Windows 7 gadgets, which as you probably know are built upon Javascript and HTML. My gadget it extremely simple. It only really has two functions:

–Read/Write a user-inputted date.–Calculate the difference between today's date and the user-given date.The date is outputted from an HTML form in this format:

dateYear = YYYY
dateMonth = MM
dateDay = DD

How would I go about saving and retrieving this data into a javascript array?

Jquery :: Reading Cookies Across Different Hosts
I have two sites - both are my projects. On site two, I need to check if the user is logged in on site one. I suppose to do this I should just create a script that puts a cookie into the body of an iframe and then read the iframe contents on site two. But I can't. Here is a code I made for testing purposes: [URL]. I got an error, that says: "Permission denied for [URL] to get property HTMLDocument.nodeType from [URL].

Reading Cookies Across Browsers
I have been using document.cookie to write and read cookies.
Unfortunately, when I open my page in Internet Explorer, I don't see
what I wrote to my cookie while in Netscape Navigator. Similarly, my
page that I opened in Netscape doesn't see what I wrote to the cookie
while in IE.

Surely there must be away for IE and Netscape to read the same
cookie information ??. Otherwise, what happens if a user just happens
to be browsing my page in both browsers? They'll expect things to be
there, and they won't be there because one browser doesn't see what
was written in the other.

Any ideas on how to get Netscape to read cookies written by IE, and
visa versa?

Cookies - Reading Them Back
document.cookie="yourdrive="+driveletter+"; expires="+"; path=/";
document.cookie="maindrive="+menuletter+"; expires="+"; path=/";

They end up looking like this in the cookie:

yourdrive E ~~local~~/ 1088 647360864 29848791 647360864 29848791 * maindrive C ~~local~~/ 1088 647360864 29848791 647360864 29848791 *

So they must be being set. I must have tried a dozen cookie reading routines and I can't read either of them back! Can anyone do it? I am sure it must be simple. But all I get is "false" all the time. Code:

Reading Cookies To Display Survey
I'm not to good at javascript. I know, but I have not learned javascript yet. I am working on a project to get a survey to pop up for new visitors on the index page of our site.

What I need to do: On load look for a cookie, if that cookie is not found run a script telling the site to pull up another page in lightview [URL] using its own "on load" command. If the cookie is there the site will not open this other page.

What I've done: I already found a way to do most of this, but I can only use a hyper link as a trigger for the site to load the other page in lightview.

Here is a link of what I have so far: [URL]

Reading Browser Cookies With JavaScript...
Now, I am not talking about some kind of malicious coding, or spyware writing by any means, but I do need it to be able to read the cookies from a site other than my own. At least I think this is what is required. What I am trying to accomplish is this; I have a stats package setup on a different domain than my live website and I am using it to track the stats of the users on my site other than paying for stats service through some other company, and it seems to be working just as I need it to, only I would like for it to be able to do a little bit more. Right now, all it is capturing form the user is their IP address, browser information and host information on their ISP. But, I would like for it to be able do more. I would like for it to be able to retrieve certain cookies generated by a different site and show me the information in which the cookies hold... I am not talking about displaying passwords or any such thing like that, I just need certain information.

Reading Cookies In A Stylesheet Switcher?
So. I've been working on this stylesheet switcher for a school project, and basicly there are 3 layouts, "Standaard", "Zwart-wit" and "Printversie". What I want is that when you select one on (for example) the homepage, I want the other pages to apply the same stylesheet. I've been trying to do that with cookies, but it doesn't even work on one page.

PHP Code:
function setup() {
var current_style = read_cookie();

Reading Webpage Cookies From Firefox Extension (XUL)
I'm creating an extension for the Firefox browser. I would like to read a cookie which was set by an HTML page using JavaScript in the XUL file. Is it possible? I tried using document.cookie, but it doesn't work:

function readCookie(name) {
var ca = document.cookie.split(';');
var nameEQ = name + "=";
for(var i=0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1, c.length); //delete spaces
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
} return "";
} function createCookie(name, value, days) {
if (days) {
var date = new Date();
var expires = "; expires="+date.toGMTString();
} else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
} function eraseCookie(name) {
createCookie(name, "", -1);

Encrypt Data With Password?
I'm creating a server which can store cookies on the web that will contain application settings. The server will accept any data, but I want to encrypt all the settings before storing them in a cookie and decrypt them when reading them out. So I can store very sensitive data like Account Usernames & Passwords in the cookies and the server cannot do anything with it.

My question is now: What is the best way to encrypt such data with a password in JavaScript on the client side? What is the most secure?

Reading Txt File And Setting Cookies Based On The Words?
Is there a way to use Javascript to read a txt file, take all the words in the txt file one by one, then create a cookie out of each of them? Ideally, I'm also looking to create a prompt which asks the user if they want to set the cookie each time.The purpose of this is that I'm looking to create some basic browser based games (with information stored in txt files), so it doesn't have to be a script which works online. Everything is just run offline. If it makes a difference, it can also be, say, a doc file rather than a txt.I understand the idea of using activeX & IE to read the txt file, and after looking through this forum, I have found a way to load the entire txt into a form. I have not been able to advance my idea beyond that however.I've used Javascript before many times for webpages, but it generally comes down to me copying and pasting code, then just changing a few keys words. What I'm quickly trying to say there is that I can use js, but I'm not that much of an expert.

Ajax :: Best And Most Secure Way To Encrypt Data?
I'm developing a website where people will be able to register and access different data via Ajax (powered by jQuery). This is all simple and i shall have no problems doing. the issue is that the data showed by Ajax needs to be secure and not available to be parsed through remote scripts. I can encrypted the data through a AES (in PHP) and decrypt successfully in javascript, but the javascript code will always be visible to everyone (after login). I can use an obfuscator and javascript encryption, but both ways, even mixed, are not secure enough and decryptable. I would prefer avoiding SSL connections, since I am trying to prevent registered users from accessing the information and the SSL connection would only prevent unregistered users from accessing the data.

Registered users will be able to earn money therefore very interested in cheating the code, this is why it has to be bulletproof.

Unfortunately the system needs definitely Ajax (the whole working principle needs to be based on Ajax). The ideal solution would be a way to save the encryption key on a place that can be saved by php and accessed by javascript, but not by users, remote script parsers etc.

Does anyone know a way to create a secure Ajax connection for this purpose?

Encrypt My Data On The Server Side Using Django?
This is my demand: User content is ultimately stored on the server side, but the preservation of data is encrypted Server side, that is, site technical staff, can not have any way to decrypt the contents of the user, as the user's password as stored on the server side is a long list of md5 encrypted characters.For encryption, we can temporarily consider only the text.The same as the password I want to process the data, but these data need to output to the user, so i have to decrypt the data on the client-side ,what can i do .

Ajax :: C# - Encrypt Service Post Request Data?
I have a .net web application that post data to server from javascript via jquery in association with wcf ui services. This enables a non post back modal.

Is it possible to encrypt the data being sent to the server so that using sniffing applications such as fiddler and firebug, the POST of the data cannot be viewed. I want to achieve this for security. The data will need to be read on the server side.

Php - Encrypt String Data So That Decoded By The Computer It Resides On?
say i have strings that are sent back and forth from the client, and server via AJAX. however i wish to securely encrypt it before being sent via the client. once it's on the server, it should be decrypted, and processed. additionally, how does password encrypting work ? user signs up, and upon entering password, its encrypted on the server, and stored on the database. what about when user logs in? is the user password being encrypted again and being matched against the one in the database?
