 Everyday we have a lot of passwords to manage corresponding to a lot of accounts we use. It's hard to remain all of these, moreover if we don't use it often. So, what we most people do is to generate only a subset of passwords easy to remain. This implies two common errors :
+
  * Password are not very strong
  * We use them for multiple accounts
 
 The best way to avoid these errors is to have a unique strong password for each account. gPass helps to reach this goal : you keep a subset of passwords and for each login/password tuple you chose, gPass returns the real password by querying a password server.
 
-To have a high level of security, all information is stored encrypted. The decryption is done on the fly when it's needed and only with user input. So, a hacker can get your password database, it will not be able to see any information !

 Usage
 -----
 
-The first thing to do is to populate your database (from your/a password server) with login/password/master key values. If you want to make strong password, there is a password generator. After that, configure your addon in addons -> gPass -> preferences to point to your password server.

 Technique
 ---------
 
-The only two columns in database are "login" and "password".
+The two columns in database are "login" and "password".
 login is compounded by "@@domain;login" encrypted with AES 256
-password encrypted with AES 256
+password is salted and encrypted with AES 256
 
 The key that encrypt these fields is sha256(masterkey)
 
+For now the only addons is done for firefox. Server side is written in PHP (with SQLite3 for database component).
+
+
+Server
+------
+
+You just have to copy server files in a directory read/write for www-data. A sample apache2 configuration file is available in ressources.
+
+You can activate/deactivate view of ciphered passwords by setting $VIEW_CIPHERED_PASSWORDS in index.php
+
+A demonstration server is available [here](http://gpass-demo.soutade.fr). It's the default server of XPI package.
+
+
+Client
+------
+
+Just install xpi package. You can have debug information by setting DEBUG in main.js.
