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."/> <meta name="keywords" content="encryption, security"/> <link href="styles.css" rel="stylesheet" type="text/css" /> </head> <body> <div> <a href="https://www.veracrypt.fr/en/Home.html"><img src="VeraCrypt128x128.png" alt="VeraCrypt"/></a> </div> <div id="menu"> <ul> <li><a href="Home.html">Home</a></li> <li><a href="/code/">Source Code</a></li> <li><a href="Downloads.html">Downloads</a></li> <li><a class="active" href="Documentation.html">Documentation</a></li> <li><a href="Donation.html">Donate</a></li> <li><a href="https://sourceforge.net/p/veracrypt/discussion/" target="_blank">Forums</a></li> </ul> </div> <div> <p> <a href="Documentation.html">Documentation</a> <img src="arrow_right.gif" alt=">>" style="margin-top: 5px"> <a href="Encryption%20Algorithms.html">Encryption Algorithms</a> </p></div> <div class="wikidoc"> <h1>Encryption Algorithms</h1> <div style="text-align:left;
