Shiro's default HashFormat implementations (as listed by the <a href="../../../../../../org/apache/shiro/crypto/hash/format/ProvidedHashFormat.html" title="enum in org.apache.shiro.crypto.hash.format"><code>ProvidedHashFormat</code></a> enum) will

Configuring this property is not as efficient as configuring a <a href="../../../../../../org/apache/shiro/crypto/hash/format/DefaultHashFormatFactory.html#getFormatClassNames--"><code>formatClassNames</code></a>
map, but it may be more convenient depending on the number of <code>HashFormat</code> implementations that
need to be supported by this factory.</div>

Check to see if the token argument is itself a fully qualified class name. If so, try to load the class

<div class="block">Heuristically determine the fully qualified <code>HashFormat</code> implementation class name in the specified
package based on the provided token.
<p/>
The token is expected to be a relevant fragment of an unqualified class name in the specified package.
A 'relevant fragment' can be one of the following:
<ul>
<li>The <code>HashFormat</code> implementation unqualified class name</li>
<li>The prefix of an unqualified class name ending with the text <code>Format</code>. The first character of
this prefix can be upper or lower case and both options will be tried.</li>
<li>The prefix of an unqualified class name ending with the text <code>HashFormat</code>. The first character of
this prefix can be upper or lower case and both options will be tried.</li>
<li>The prefix of an unqualified class name ending with the text <code>CryptoFormat</code>. The first character
of this prefix can be upper or lower case and both options will be tried.</li>
</ul>
