Recently I have been thinking about my online security. It lead me on a brief search for portable applications which at least give me the feeling that I am more secure that I am now.
The first step was to make my e-mail traffic more secure and make it more difficult for all kind of snoopers to read in on my e-mail. There is great portable version of Thunderbird, which can easily be extended with GPG encryption. It is simply a matter of installing the GPG for Thunderbird extension and then Enigmail to encrypt and sign your outgoing traffic. Of course you need to have a strong passphrase, but once that is done, it is no longer a problem to send (and receive) encrypted e-mail messages that would give various governments some headaches.
The second step was to obscure my going arounds in the digital realm. Could I obscure the digital crumbs that I leave behind while surfing the net?
