Skeleton Key is an alternative way to manage passwords. Rather than keeping a database for every website, you merely have one master password that is used in combination with a "site key" and your username. The site key is a site-specific string. All three pieces of data are cryptographically hashed repeatedly using the ultra-secure PBKDF2 algorithm. Changes in v3: - Fixed bugs with site key suggestion. Changes in v2: - Use current tab's URL as a suggestion for the site key.
