Here's How to Best Secure Your Data Now That the NSA Can Crack Almost Any Encryption
Reports suggest the NSA is capable of cracking many of the encryption protocols being used today. Here are tools that minimize that risk.

PC World — The latest Snowden-supplied bombshell shook the technology world to its core on Thursday: The NSA can crack many of the encryption technologies in place today, using a mixture of backdoors baked into software at the government's behest, a $250 million per year budget to encourage commercial software vendors to make its security "exploitable," and sheer computer-cracking technological prowess.
To some extent, it's not surprising to hear that the U.S. spy agency is doing spy agency stuff but, given theA recentA surveillancerevelations and the fact that other countries likely have similar capabilities, the news is certainly worrying. To make matters worse, it came just a day after Pew reported that 90 percent of Internet users have taken steps to avoid surveillance in some way.
All is not lost, however. While the stunning reports failed to name exactly which companies and encryption technologies have been compromised by the NSA, you can minimize the chances that your encrypted communications will be cracked by the government--or anyone else. Read on.
Embrace open source
Now that we know that corporations--or at least individuals in corporations--have worked with the NSA to build backdoors into encryption technology, privacy buffs should give commercial encryption technology (such as Microsoft's BitLocker) the hairy eye.
You're better off using tools that employ open-source or public-domain encryption methods, as they need to work with every vendor's software and, in the case of open-source encryption, can be scrutinized for potential security flaws.
With that in mind, here are some tools worth checking out:
- Truecrypt for encrypting sensitive files, folders, and entire drives on your PC.
- GPG, an open-source implementation of the OpenPGP protocol used to encrypt email communications. Be sure to read up on why standard-compliant email messages can never truly be secure, though.
- TAILS, a.k.a. The (Amnesic) Incognito Live System, a Linux distribution built with security and anonymity in mind. TAILS comes packed with numerous privacy and encryption tools baked in, including Tor, which allows you to browse the web (mostly) anonymously and access a Darknet of so-called "Hidden Services" that grant anonymity to both web servers and web browsers. Bruce Schneier--a longtime security guru who has actually read the documents detailing the NSA's encryption-busting methods--recommends using Tor and Hidden Services toA thwart NSA surveillance. TAILS is meant to be used as a live CD, which means you can boot it from a disc or USB drive, and your data is wiped when you power off your system.
- Off-the-record messaging, or OTR, a cryptographic protocol for encrypting and authenticating instant-messaging communications. The protocol uses AES and SHA-1 standards and comes baked into TAILS and is recommended by Schneier even in the wake of the NSA revelations. Here's a list of IM software that supports OTR.
