Security

Captcha Code Generator JQuery Script allows you to create random images.A six character code that has to be entered by the user before submitting the form. This ensures that the web forms are not automatically submitted.

"Chroma-Hash is a jQuery plugin that dynamically visualizes secure text-field values using ambient color bars. Password entry can be frustrating, especially with long or difficult passwords. On a webpage, secure fields obscure your input with ""¢'s, so others can't read it. Unfortunately, neither can you""”you can't tell if you got your password right until you click ""Log In"". Chroma-Hash displays a series of colored bars at the end of field inputs so you can instantly see if your password is right. Chroma-Hash takes an MD5 hash of your input and uses that to compute the colors in the visualization. The resulting color pattern is non-reversible, so no one could know what your password just from the colors."

Users can select the characters that don’t appear in the keyboard using the keypad widget whilst continuing typing others characters in their normal keyboards.

A modular and extensible collection of cryptography functions, for encryption and hashing. Includes Blowfish, MD5, SHA functions, XXTEA, and others, all coded from easy-to-read and object-oriented JavaScript code.

Do you want to make sure that your visitors can only access your content via your domain. This Javascript is very useful for this. This javascript verifies that the request for the page (containing the script) was made from a page on your domain.

This password generator Javascript will generate random passwords with a variety of options. You can include numerals, symbols and regular characters. There is also an option to add custom characters plus you can also define the passwords desired length.

The idea is to 3DES encrypt all content of the chat with javascript, and then send it to the server, where it is stored in encrypted form. When another chat client refreshes the chat file, it will decrypt the lines in the chat with a shared code phrase. This allows for sticky, non-refreshing pages where it is possible to store a pass phrase for key generation and encryption without sending it over the internet. Thus only the group in know of the phrase will be able to decrypt the data. - all data is encrypted before send - no version of the key exist on the server, the lines is stored as encrypted strings - on return, the encrypted data is decrypted by javascript into human readable format. The AnoChat 1.1 also comes with 20 different skins, and a tool to help you create your own. It requires only a standard php-distro to run.

Email harvesting is a real problem nowadays; publishing an email address on a web page means exposing it to automated email collection softwares. Once it's been collected there no way of getting rid of spam. The best way to avoid this is obfuscating and encoding email addresses; this simple javascript script does exactly that. It splits an address in six different parts, so that bots are not able to recognize it, and it also encode the @ symbol and the . (dot) using ascii codes, just to make it harder for bots to decode it. Even if the email harvesting software can read javascript and put the different parts of the address together, it would obtain an useless text like this: myaddress@mydomain 6;com instead of [email protected].

A very simple and powerfull Anti Text Selection javascript !!!! This script is useful if you don't want to give the possibility to your visitors to select texts on your website (avoid a copy/paste for exemple).

This is a simple JavaScript that allows you to protect your HTML source code and images of your web sites by preventing visitors from right-clicking on your sites. An specified alert box will prompt out when visitors right click their mouse.

Uses 448-bit Blowfish encryption to create password protected web pages. The encrypted pages use JavaScript to self-decrypt in a standard web browser, but only after the correct password has been entered. Tested in all the most popular browsers, including: IE, FireFox and Chrome.

Disable viewers' ability to select text on your page by installing this script. With it, dragging the mouse over text has no effect.

Encrytion of Strings with Javascript like ARCFOUR. but no trademark. Security requires that the key is used only once.

An example of a simple JavaScript encoding of an html page. When the page loads you are prompted for a password. Enter the correct password and the page displays properly - enter the wrong password and you see only an "Invalid password" message. Viewing the source of the page shows only the encoded content. The encoding is fairly basic but should stop all but the most determined script thieves, spam-bots, or spiders. Tested in Mozilla on Linux, IE on Windows, and Safari on Mac.

This encryption script make a series of consecutive encryption steps to ensure security. 11 key values are derived from a key sentence and used to hide all possible origin patterns. The encrypted result is a number raw string, which can be decoded for each one who knows the key sentence.

The algorithm is designed to transfer an encryption key between two parts electronically in a hidden fashion. This free test script simulate such an exchange beween two parts. It is written for the best owerview and understanding possible.

ExD'or is a useful JavaScript application for encrypting and decrypting .txt files. It uses a 4-bit paradigm to convert any text string into a scrambled ASCII string. Using it you can easily protect your documents from being viewed from other people, because once encrypted a decryption key of your own will be required for the reverse process.

Use hash() method of QControl class to convert a string to integer hash value. My original algorithm takes a moment to convert and guarantee secure and collision-free convolution even of short strings.
