Swordfish is an experiment in builidng a group-optimized password management app. It is currently very alpha. Browse all the issues to see what features are planned.
Storing passwords on a server might seem like filling a lake in Alaska with honey and expecting to keep bears out. I don't think it's like that. Why?
Even if an attacker gets access to your server or database, all secure items are encrypted client side. The server has no idea what it is storing and no way of decrypting it.
When you sign up, a RSA public/private keypair is generated in your browser. All sensitive data is encrypted with your private key, which is password-protected and never transferred to the server. No sensitive data is ever transmitted over the wire unless it is encrypted with secrets only available on the client.
