IMPORTANT: Please understand the risks of password generators: https://crypto.stackexchange.com/a/5691/291

Create strong passwords for different websites (or anything else) using a single secret key. If you lose your password for a website, you can regenerate it if you remember your secret key, username, and address of the web site. There's no need to remember or store multiple passwords if you can derive them from your master key.

How to use
----------------

1. Make up a secret master key (at least 16 characters for better security) and remember it. Keep it secret! You will use it every time you need to generate a password.

2. Click on the extension icon.

3. Enter your username for the website. It can be anything, you just need to remember it.

4. Enter URL of the website (it is prefilled).

5. Click a button: "Show" to generate and show password, or "Fill" to generate password and try to fill form on the current webpage with username and password (pressing Enter does "Fill").

Examples
--------------

For example, your secret key is: "my super secret" (do not actually use this, think of something better and longer)

Username: tester
URL: google.com

Your generated password will be: Juq5MzGrXU7zivT13MHdpXGzq
Use it for your account.

Username: somebody_else
URL: twitter.com
Generated password: ydPFMc7isTa1mBlFOFiYSmjXV

Every time you enter "my super secret" plus "somebody_else" as username and "twitter.com" as URL, you will get exactly the same generated password as above.

Algorithm
--------------

password = base64(pbkdf2(secret, username@url))

PBKDF2 uses SHA-256 and 5000 iterations. Cuts password to specified length (25 by default).

This extension doesn't use any web services, everything is done on your computer.

Warning for reasonably paranoid: there is a security risk in how Chrome handles autoupdates of extensions: if somebody gains access to Google servers or my developer account, they could put backdoor in this extension and re-upload it. You would get this modified version, and Chrome would not notify you. If you want to avoid this risk, use the source code linked above to install the extension on your own.
