Mailvelope – OpenPGP Encryption for Webmail
I really wish I wouldn't have to store the private key together with a browser extension I don't trust (no offense to the author(s)).<p>It would be amazing if Windows, Mac and Linux all would support some sort of "safe" gpg/pgp storage. I don't remember if I'm making this up, but i believe the OS X keyring can do this. There really should be no reason why every application should roll their own storage and interaction of the private key.
