General ideas
Single signon
The user shouldn't have to enter his password twice (once for logging in, once for opening the default wallet). The main problem is that the wallet will still have to be password protected, so we need a way to transmit the password to the daemon.
Gnome keyring provide a hack (is it?) for this:
Upon authenticating the user, or logging into the session, the PAM module checks for the GNOME_KEYRING_SOCKET environment variable. If not present it assumes that gnome-keyring-daemon is not running for that session.
- If the auto_start argument is present in in the PAM config, it then starts it as a daemon.
- The gnome-session process does the same checks, which prevents it from starting twice.
Upon authenticating the user, the PAM module tries to unlock the 'login' keyring with the password entered by the user.
- If the 'login' keyring does not exist it is created with the user's password.
- If the 'login' is the first and only keyring it will become the default keyring.
We could basically do something quite similar to this for kwallet:
- Extract the kwalletd to run standalone.
- Adapt/rewrite the gnome mini-pam module to start kwalletd and pipe the password to it using some sort of socket.
- This would probably have to be optional (default policy might be to NOT enable it and let the user choose the level of security he wants).
- It's important to consider security implications.
Sascha Peilicke will look into this matters and come up with a plan. This is a core issue so we'll have to discuss it on kcd.
Inter-desktop integration
Sascha proposed making kwallet/keyring cross-desktop so the user would need only a single authentication backend running. For this to work we'd either need a single API and multiple implementations or a common backend implementation - probably something for freedesktop.org. Coordinating that would take a hell lot of time so this is more or less a long-term goal. In the process we have to consider binary API compatibility.
It would also be nice to have software not tied to a desktop use this (ie. Firefox).
Make sure passwords are saved
This relates to Bug bug #105752. We should come up with a way to store passwords before a session crashes. Of course shouldn't disturb the user (which is why I (Lemma) don't like the timed solution proposed by a comment in this report). Complete rewrites of the kwl file should happen at points in time when the user is used to waiting (ie. opening the wallet after a crash, saving the session).
General idea: On adding new passwords, append the encrypted password entries to the kwl file without rewriting it completely. If the session crashes the passwords are still here. The kwl file could be cleaned up upon reopening the wallet. As far as I know this might work. We'll see.
Overhaul the interface
The interface will have to be reworked. We were talking about:
- Overall goal:
- Make the manager a little shinier and a breeze to use
- Make it a program that eases managing personal account data rather than an editor for account data stored by various programs (yes, I know it already is, but the emphasis is on EASES :-)).
- Using model/view classes
- Improving usability (have a look at various bugreports concerning that)
- Maybe choose a one-window solution instead of the current two-window solution
- No need to reinvent the wheel, learn from what others have done, eg:
