<div class="snap_preview">REDHAT에서 지원되는 알고리즘은 <a href="http://en.wikipedia.org/wiki/Data_Encryption_Standard">DES</a>, <a href="http://en.wikipedia.org/wiki/MD5">MD5</a>, and <a href="http://en.wikipedia.org/wiki/SHA_hash_functions">SHA-256/512</a> 이다. <a href="https://www.redhat.com/archives/anaconda-devel-list/2008-February/msg00134.html">Rawhide</a> 로 업데이트 한 후에 가능할 것이다. <p> 새로운 알고리즘은 단지 Kickstart를 통해 설정이 가능할 것이다.<span id="more-813"></span><br></p>
<h2>DES</h2>
<pre>authconfig --enableshadow --passalgo=descrypt<br>rootpw fedora<br></pre>
<h2>MD5</h2>
<pre>authconfig --enableshadow --enablemd5<br>rootpw fedora<br></pre>
<p>or</p>
<pre>authconfig --enableshadow --passalgo=md5<br>rootpw fedora<br></pre>
<h2>SHA-256</h2>
<pre>authconfig --enableshadow --passalgo=sha256<br>rootpw fedora<br></pre>
<h2>SHA-512</h2>
<pre>authconfig --enableshadow --passalgo=sha512<br>rootpw fedora<br></pre>
<p>만약 위의 예에 있는 암호화된 root패스워드를 제공한다면, 다시 암호화되지는 않을 것이다.</p>
