pbkdf2 generating pwd
Generate a unique secure password for a website: The password is generated from the website's domain, a password key you give and a salt (set when first starting the extension). To connect on the website, simply regenerate the derived password from the domain name and your password key. Nothing except the salt and number of iterations of the hash function is stored: you have to remember your password key and enter it each time you use this extension. Please use a relatively secure password even if the key derivation function will protect it against most attacks.
