<div class="textblock"><p>A default implementation for password strength validation. </p>
<p>This implementation uses <a href="http://www.openwall.com/passwdqc/,">http://www.openwall.com/passwdqc/,</a> a password checker commonly used to validate user account passwords in Linux/BSD distributions.</p>
<p>The default settings are not as restrictive as those used originally by passwdqc (which could be frustratingly restrictive for a web application). You may want to make it change the settings to demand stronger passwords for sensitive applications. </p>

<p>Enumeration for a password type. </p>
<p>An entered password will be classified as one of these types, based on the different characters used.</p>
<p>The classification uses the concept of character classes, and defines five classes:</p>
<ul>
<li>lower case letters</li>
<li>upper case letters</li>
<li>numbers</li>
<li>other ascii characters</li>
<li>unknowns (i.e. multi-byte UTF-8 sequences)</li>
</ul>
<p>For determining the number of classes, capitializaiton of the first letter of a word, or appending a number, does not count as an extra class. </p>
