Crypto filesystems keep your data safe – even if someone steals your computer. The recent popularity of portable PCs has brought increased awareness about the need for protection, but even users with desktop systems have reasons for wanting to ensure that their data stays secret. Linux offers a number of encrypted filesystem options – each with a different approach to the encryption problem. We took a look at some of the alternatives, with the goal of providing some insights on encryption techniques, code quality, and the relative merits of the various solutions. We examined the following encrypted filesystems: • Loop-AES • DM-Crypt • Truecrypt • Crypto-FS • Enc-FS In addition to looking at technologies and techniques, we will also examined some performance parameters for these encryption options.
