<p>Chacha20 comes in three different variants.</p>
<p>The AVX variant is found in file <code class="docutils literal notranslate"><span class="pre">Hacl_Chacha20_Vec128.h</span></code> and exposes two
functions.</p>
<div class="highlight-c notranslate"><div class="highlight"><pre><span></span>

<p>In addition to the encryption, there’s also
<code class="docutils literal notranslate"><span class="pre">Hacl_Chacha20_Vec128_chacha20_decrypt_128</span></code> but since they do exactly the same
thing I’m not sure why there’s two variants.</p>
