<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>Kuznyechik</h1>
<p>Kuznyechik is a 128-bit block cipher first published in 2015 and defined in the National Standard of the Russian Federation&nbsp;<a href="http://tc26.ru/en/standard/gost/GOST_R_34_12_2015_ENG.pdf">GOST R 34.12-2015</a> and also in
<a href="https://tools.ietf.org/html/rfc7801">RFC 7801</a>. It supersedes the old GOST-89 block cipher although it doesn't obsolete it.</p>
<p>VeraCrypt uses Kuznyechik with 10 rounds and a 256-bit key operating in <a href="Modes%20of%20Operation.html" style="text-align:left; color:#0080c0; text-decoration:none.html">
