If you think data is more precious than ever, you should certainly consider its security to be a priority. And with more and more businesses working with multiple platforms, you have to be prepared to work with encryption on just about every business-ready operating system available. Including Linux. Fortunately, you have plenty of encryption-ready tools to choose from.
But which tools should you be looking at? If you open up, say, the Ubuntu Software Center, you'll find the majority of tools available (under the "encryption" search results) to be nothing more than libraries to resolve dependencies. Dig a bit deeper, though, and you'll find everything you need for easy-to-use encryption. I've uncovered five such tools for encryption on the Linux platform.
