Transparent encrypted virtual disks for Android (we call it IOCipher)

When using phones, laptops, computers, etc. it feels like a private experience, as if our screen was the same as a piece of paper, and when that paper is gone, then no one can see it anymore. Digital media works very differently. While the user interface portrays the deletion of files as very final, for someone with the right tools, it is actually not hard to recover deleted files. Also, digital information takes up so little space, we now regularly carry vast amounts of information in our pockets. [Read More]

Adventures in Porting: GnuPG 2.1.x to Android!

PGP started with Phil Zimmerman’s Pretty Good Privacy, which is now turned into an open IETF standard known as OpenPGP. These days, the reference OpenPGP platform seems to be GnuPG: its used by Debian and all its derivatives in the OS itself for verifying packages and more. It is also at the core of all Debian development work, allowing the very diffuse body of Debian, Ubuntu, etc developers to communicate and share work effectively while maintaining a high level of security.

Don’t Get Burned, Anonymize Your Fire

Thanks to Jesse Vincent, aka @obra of the K-9 mail project, we can say that Orbot (Tor on Android) and Orweb (Privacy Browser) work just fine on the new Amazon Kindle Fire. This means that while everything you do through Amazon’s store and browser are tracked and accounted for by Team Bezos, you can use our apps to more safely and privately access web content through the Tor network. While we are mostly Nook Color fans around here, we know that the Kindle Fire is going to be quite popular this Christmas, and are glad to see that mobile privacy now has a toehold on the device from Seattle.

Orbot Update: New Setup Wizard at Startup

We’ve been working away at the 0.0.9 release of Orbot over the last few months, and have put a decent amount of effort into usability. Specifically, we hoped to better communicate to users what it means to run Tor on your Android phone. In addition, we wanted to clearly lay out how the various configuration options help to improve your mobile web anonymity and ability to circumvent web filters and tracking by your mobile service provider.

How To: Lockdown Your Mobile E-Mail

Update 2015-04-27: _We now recommend OpenKeychain over APG, the app described in this blog post. The set up is drastically easier, so you probably don’t even need this HOWTO anymore. Start by downloading K-9 and OpenKeychain, then go into OpenKeychain and start the config there._ Over the past few years it’s become increasingly popular to sound the call that ‘email is dead{#y8a0}.’ And while many complementary forms of synchronous and asynchronous communication – from IM to social networking – have evolved since email first came on the scene, it’s hard to see email suddenly disappearing from its role as the most important way organizations communicate.
