Password Generator

Remember a single password to generate repeatable, secure passwords for multiple sites.

Chrome implementation of Nic Wolff's SHA1 password generator ( http://angel.net/~nic/passwd.sha1.1a.html ).

All actual hashing code taken directly from link above.

Extension adds a 'save' button to store the master password (optionally), and will try to pre-fill the site name with the current site's root domain name.

Last three characters of password will always be "1a!" for sites that require a combination of letters, numbers and/or punctuation.
(new) Optionally, they can be set to "1a" for compatibility with angel.net.
