<p class="phpdocumentor-summary">Pure-PHP implementation of RC4.</p>
<section class="phpdocumentor-description"><p>Uses mcrypt, if available, and an internal implementation, otherwise.</p>
<p>PHP version 5</p>
<p>Useful resources are as follows:</p>
<ul>
<li><a href="http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt">ARCFOUR Algorithm</a></li>
<li><a href="http://en.wikipedia.org/wiki/RC4">- Wikipedia: RC4</a></li>
</ul>
<p>RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at Wikipedia. This class is named RC4 and not
ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.</p>
<p>Here's a short example of how to use this library:
<code class="prettyprint"></p>
<?php
include 'vendor/autoload.php';
$rc4 = new \phpseclib3\Crypt\RC4();
$rc4->setKey('abcdefgh');
$size = 10 * 1024;
$plaintext = '';
for ($i = 0; $i < $size; $i++) {
$plaintext.= 'a';
}
echo $rc4->decrypt($rc4->encrypt($plaintext));
?>
