Password manager type application, is this tough stuff?

There is a password manager application for the MAC, and I was curious as to how one would go about developing such a fine piece of software.

I don't know much about the mac, just getting into xcode and iphone development actually.

The idea is, when you are at a website, and login it pops-up and asks if you want to save the login/password to the application.

You can also click on a previously saved login, and it will open up firefox and login for you.

How would you know when a browser is open, and when a form gets submitted?

Wh开发者_JAVA技巧at kind of application would this be i.e. project type in xcode?

I'd start by reading up on KeyChain, since that already does most of the work 1password is doing (i.e. securely storing passwords). As for bring up a prompt in web browsers etc, that's just a plugin for each browser it works with, so you'd have to dive into the plugin documentation for each web browser you wanted to support.

In short, it's not mind bogglingly difficult, but it's not a small task by any means. If you don't care about the browser integration you could probably write a thin wrapper around KeyChain quite easily, though I've never done it, so don't take my word as gospel.
