MacOS X stores a lot of passwords in its Keychain. In theory one could use LastPass to also synchronize this store across multiple computers. What would be necessary for that? A tool for Mac that can export the Keychain Content to LastPass's storage and re-import passwords back from there.
As a long time Mac programmer, I'm quite familiar with the Keychain API (I hate it like hell, because it's ugly like hell, but I know it very well, have been using it thousand of times). Am I'm willing to offer help. What I'm missing is a developer documentation that explains detailed enough how an application could access the LastPass vault and that could read passwords from there as well as writing passwords to it.
I'm very interested in writing such a tool. I think all passwords could be easily synchronized that way across multiple Macs. I'd be giving out such a tool for free. I'm also willing to share the source code with you, if you like. However without a developer documentation I had to reverse engineer all the information of the JS code, which is possible, but hard work.
I'm also thinking about an offline version you can save onto mobile phones written in Java, so you can take your whole vault with you wherever you go encrypted on your mobile phone. Again, I need a developer documentation for that. It would be great if you can also create "sites" on the phone and sync these back to the vault (e.g. if you must create a password while away of any computer).
So here's another offer: If you provide me with the necessary information in any format of your choice, I'm also willing to help writing a developer documentation for you which I will be donating to this great project for free, so you can put it online on your web page.
So free help is available for you guys, just contact me about it and I will do my best to help you out where I can. If you want to schedule a live chat or similar, just let me know (I have MSN, ICQ, AIM, Skype). The more software there is that works with your great service, the better for the service. I want to help you making this more a community project than a 4 men show
This cuts your workload, working time, costs, etc.
