!!! Overview
[{$pagename}] has a file system centric approach towards [Encryption], and a data centric approach.

[{$pagename}] is one of the [Data States] for [data]

!! Lets start with the first one.
[File System] centric approach is not about the [data] itself, but the storage it is stored in. It is about encrypting disks, [Disk Partitions] and volumes (that span multiple disks or [Disk Partitions]). It is also about an encrypted file in which the actual data is stored in the form of files and folders. And also your temporary files in the hibernation and swap space (pagefile) can be encrypted. These last two are especially important if you want to secure your environment for forensic analyses.

The data-centric approach is the [encryption] of the data itself. Storing passwords is probably the most common known variant of it. But it is also possible to encrypt entire databases or specific records and/or attributes in a database. The focus here is the data it self, and not the [File System] it is stored on.

There are tons of examples for implementation here to choose from. There is an extensive list of disk encryption software on Wikipedia. When selecting your tool for the job, consider your policy towards [Hashing] and [Encryption]. There might be also other corporate policies that state whether you should or should not use open source tools. There is no right or wrong here, other then it is __not__ wise to use software which uses outdated algorithms.
