"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."

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.
