+<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."/>

+<h1>Cascades of ciphers</h1>
+<p>&nbsp;</p>
+<h2>AES-Twofish</h2>
+<p>Two ciphers in a cascade [15, 16] operating in XTS mode (see the section <a href="Modes%20of%20Operation.html">
+<em>Modes of Operation</em></a>). Each 128-bit block is first encrypted with Twofish (256-bit key) in XTS mode and then with AES (256-bit key) in XTS mode. Each of the cascaded ciphers uses its own key. All encryption keys are mutually independent (note that
+ header keys are independent too, even though they are derived from a single password &ndash; see
+<a href="Header Key Derivation.html"><em>Header Key Derivation, Salt, and Iteration Count</em></a>). See above for information on the individual cascaded ciphers.</p>
+<h2>AES-Twofish-Serpent</h2>
+<p>Three ciphers in a cascade [15, 16] operating in XTS mode (see the section <a href="Modes%20of%20Operation.html">
+<em>Modes of Operation</em></a>). Each 128-bit block is first encrypted with Serpent (256-bit key) in XTS mode, then with Twofish (256-bit key) in XTS mode, and finally with AES (256-bit key) in XTS mode. Each of the cascaded ciphers uses its own key. All encryption
