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="Documentation.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="Technical%20Details.html">Technical Details</a> </p></div> <div class="wikidoc"> <h1>Technical Details</h1> <ul style="text-align:left; margin-top:18px; margin-bottom:19px; padding-top:0px; padding-bottom:0px"> <li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Notation.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Notation</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Encryption%20Scheme.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Encryption Scheme</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Modes%20of%20Operation.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Modes of Operation</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Header%20Key%20Derivation.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Header Key Derivation, Salt, and Iteration Count</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Random%20Number%20Generator.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Random Number Generator</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Keyfiles.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Keyfiles</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Personal%20Iterations%20Multiplier%20%28PIM%29.html">PIM</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="VeraCrypt%20Volume%20Format%20Specification.html" style="text-align:left; color:#0080c0; text-decoration:none.html">VeraCrypt Volume Format Specification</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Standard%20Compliance.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Compliance with Standards and Specifications</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="Source%20Code.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Source Code</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="CompilingGuidelines.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Building VeraCrypt From Source</a> <ul> <li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="CompilingGuidelineWin.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Windows Build Guide</a> </li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px"> <a href="CompilingGuidelineLinux.html" style="text-align:left; color:#0080c0; text-decoration:none.html">Linux Build Guide</a> </li> </ul> </li></ul> </div><div class="ClearBoth"></div></body></html>
