How secure is Blackbird?
The security of Blackbird depends on what kind of encryption is in use, and the overall security of the machine on which it is used. A machine that is infected with a virus that logs keystrokes, or some other eavesdropping measure, cannot be deemed safe. Blackbird deals mainly with information as it resides on the internet (such as a blog posting or an online article) and decrypts it when it reaches the browser. Additional measures of the overall security of the client machine, and password management, are up to the user.
