<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."/>

<h2>Volume Clones</h2>
<p>Never create a new VeraCrypt volume by cloning an existing VeraCrypt volume. Always use the VeraCrypt Volume Creation Wizard to create a new VeraCrypt volume. If you clone a volume and then start using both this volume and its clone in a way that both eventually
 contain different data, then you might aid cryptanalysis (both volumes will share a single key set). This is especially critical when the volume contains a hidden volume. Also note that plausible deniability (see section
<a href="Plausible%20Deniability.html"><em>Plausible Deniability</em></a>) is impossible in such cases. See also the chapter
<a href="How%20to%20Back%20Up%20Securely.html">
<em>How to Back Up Securely</em></a>.</p>
