CyanogenMod, the free and open-source alternative Android distribution, has folded the protocols of the encrypted text-messaging app TextSecure into its latest builds, a boon for Android users concerned with privacy and security.
Android is an extremely versatile operating system, but its openness also makes it vulnerable to all manner of intrusions. CyanogenMod helps keep your Android experience basic and safe by replacing the build of Android installed by Google, device makers or wireless carriers.
There are a number of reasons to install CyanogenMod: more security fixes, faster updates to new versions of Android, features unavailable on regular Android builds, and a lack of bloatware, the junk software that comes preinstalled on many phones and tablets.
Because it allows fine control over Android and takes a little technical know-how to install, CyanogenMod is a favorite among the hard-core techie crowd. Because this audience is also very interested in matters of security and privacy, automatically encrypting text messages is the logical next step.
There's a good chance that no one's reading your text messages. Neither cybercriminals nor government security agencies have much interest in when you need to pick your kids up from school or what you thought of that abysmal Yanks-Sox game. However, by default, text messages exist in plaintext, meaning that a third party could access them without much trouble.
If you want to encrypt text messages, either on principle or because you're doing something you'd rather interlopers didn't know about, there are programs and add-ons that will do it for you, but they're generally cumbersome. The two conversers usually need to speak in real-time and wait for each message to verify a secure connection before it sends.
The CyanogenMod TextSecure protocol comes by way of Open WhisperSystems, a collaboration between security experts Moxie Marlinspike and Stuart Anderson. The protocol is extremely unobtrusive, and has no aesthetic effects on CyanogenMod's default texting program whatsoever.
TextSecure also allows asynchronous encrypted texting, meaning you can send a text to a recipient who is unavailable (due to a phone being off, for example) and have him or her receive it later. This is standard practice for unencrypted texts, but harder to pull off with secure ones.
If you want your texts to remain hidden from prying eyes, but lack either the skill or inclination to install CyanogenMod, you can also get TextSecure as a stand-alone app for most Android devices via the Google Play store. A version of TextSecure for iOS is also in the works, although it's not really worth a look yet unless you want to contribute to its open-source programming.
As of today, TextSecure is a part of CyanogenMod by default, so privacy-minded users will want to upgrade as soon as possible.
Consumers still running the version of Android their phones and tablets shipped with may want to look into CyanogenMod too. More current Android software, better security updates and encrypted texts is an attractive package, even though CyanogenMod comes with a few pitfalls as well (specialized Google software — like Gmail and Drive — work with a few hiccups, if at all).
Keep in mind that installing CyanogenMod may void your device's warranty, so think carefully about what you like better: your privacy or your customer support.
