Integrating Crypto Identities with Android

ver the past couple of years, Android has included a central database for managing information about people, it is known as the ContactsContract (that’s a mouthful). Android then provides the People app and reusable interface chunks to choose contacts that work with all the information in the ContactsContract database. Any time that you are adding an account in the Settings app, you are setting up this integration. You can see it with Google services, Skype, Facebook, and many more. [Read More]

Keys, signatures, certificates, verifications, etc. What are all these for?

For the past two years, we have been thinking about how to make it easier for anyone to achieve private communications. One particular focus has been on the “security tokens” that are required to make private communications systems work. This research area is called internally Portable Shared Security Tokens aka PSST. All of the privacy tools that we are working on require “keys” and “signatures”, to use the language of cryptography, and these are the core of what “security tokens” are. [Read More]

Getting keys into your keyring with Gnu Privacy Guard for Android

Now that you can have a full GnuPG on your Android device with Gnu Privacy Guard for Android, the next step is getting keys you need onto your device and included in Gnu Privacy Guard. We have tried to make it as easy as possible without compromising privacy, and have implemented a few approaches, while working on others. There are a few ways to get this done right now. Gnu Privacy Guard registered itself with Android as a handler of all the standard OpenPGP MIME types (application/pgp-keys, application/pgp-encrypted, application/pgp-signature), as well as all of the OpenPGP and GnuPG file extensions (.

Modernizing Expectations for the Nouveau Secure Mobile Messaging Movement

The tl;dr of this lengthy (tho entertaining and immensely important!) post is this: Stopping with “We support OTR” or “We support PGP” is not enough anymore. There are at least seven, if not more, very important security features that any app claiming to provide secure messaging must implement as soon as possible, to truly safeguard a user’s communication content, metadata and identity. Note: The names “Gibberbot” and “ChatSecure” are used interchangeabley below, as we are in the midst of an app rebrand. [Read More]

GnuPG for Android progress: we have an command line app!

This alpha release of our command-line developer tool brings GnuPG to Android for the first time! GNU Privacy Guard Command-Line (gpgcli) gives you command line access to the entire GnuPG suite of encryption software. GPG is GNU’s tool for end-to-end secure communication and encrypted data storage. This trusted protocol is the free software alternative to PGP. GnuPG 2.1 is the new modularized version of GnuPG that now supports OpenPGP and S/MIME. [Read More]

Introducing InformaCam

These are interesting times, if you go by Times Magazine as an indicator. The magazine’s person of the year for 2011 was The Protester, preceded in 2010 by Facebook founder Mark Zuckerberg. Both entities partners with equal stake in freely sharing the digital content that shows the world what’s going on in it, at any time, from behind any pair of eyes.Also casting in their lot with the others is Time Magazine’s 2006 person of the year, You: the You that puts the “you” in “user-generated content;” the You whose miasma of bits, bytes, and the powerful images they express are becoming increasingly problematic.

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.
