+<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>
+<meta name="description" content="VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/>

+<p>Designed by Bruce Schneier, John Kelsey, Doug Whiting, David Wagner, Chris Hall, and Niels Ferguson; published in 1998. It uses a 256-bit key and 128-bit block and operates in XTS mode (see the section
+<a href="Modes%20of%20Operation.html"><em>Modes of Operation</em></a>). Twofish was one of the AES finalists. This cipher uses key- dependent S-boxes. Twofish may be viewed as a collection of 2128 different cryptosystems,
+ where 128 bits derived from a 256-bit key control the selection of the cryptosystem [4]. In [13], the Twofish team asserts that key-dependent S-boxes constitute a form of security margin against unknown attacks [4].</p>
