Say hello to the NSA

gAES / hangoutAES

Your chats will look like this : U2FsdGVkX1/4B5+XAraGEF3rsf/WpYbyCsB+IKylJXc= to the eyes off all, (except your contact)

gAES is a (greasemonkey) user script that encrypts/decrypts (AES) your google chats (gTalk or hangout) with one or more contacts

• Install gAES.user.js to encrypt/decrypt your conversations with gTalk
• Install hangoutAES.user.js to encrypt/decrypt your conversations with google Hangouts (g+ and gmail if you enable it...)

---

##Installation

Both you and the contact you want to chat with have to install gAES/hangoutAES.
After installing GreaseMonkey,

• If you use gTalk click here : gAES
• If you use google Hangouts click here : hangoutAES

GreaseMonkey will suggest you to install the script, do it.

##Configuration

Both you and the contact you want to chat with have to configure gAES/hangoutAES.
After installing gAES/hangoutAES, it's time to configure it.
Click on : the GreaseMonkey icon> Manage User Scripts > gAES options > Edit this User Script

let's take an exemple:
I'm Walker Evans (on gmail) and I want to chat securely with August Sander (on gmail)

• I (Walker Evans) have to configure the begining of the script like this :

var whiteList = [{
                    user       : 'August Sander',
                    passphrase : 'abcDEF-123456-same-for-both-users'
                }]; 

• And August Sander have to configure it like this :

var whiteList = [{
                    user       : 'Walker Evans',
                    passphrase : 'abcDEF-123456-same-for-both-users'
                }]; 

Save, refresh the gmail tab, et voilà !

##Usage

gAES/hangoutAES encrypts your message on the fly, then decrypts all messages in the chatbox, every seconds (you can configure it).
When reading chat history gAES/hangoutAES adds a decrypt button to decrypt the encrypted conversation (yes).
