 <P>
 A <code>Hash</code> implementation that allows any <A HREF="http://java.sun.com/javase/6/docs/api/java/security/MessageDigest.html?is-external=true" title="class or interface in java.security"><CODE>MessageDigest</CODE></A> algorithm name to
  be used.  This class is a less type-safe variant than the other <code>AbstractHash</code> subclasses
  (e.g. <A HREF="../../../../../org/apache/shiro/crypto/hash/Sha512Hash.html" title="class in org.apache.shiro.crypto.hash"><CODE>Sha512Hash</CODE></A>, etc), but it does allow for any algorithm name to be specified in case the other subclass
  implementations do not represent an algorithm that you may want to use.
  <p/>
  As of Shiro 1.1, this class effectively replaces the (now-deprecated) <A HREF="../../../../../org/apache/shiro/crypto/hash/AbstractHash.html" title="class in org.apache.shiro.crypto.hash"><CODE>AbstractHash</CODE></A> class.  It subclasses
  <code>AbstractHash</code> only to retain backwards-compatibility.

 <DD>Creates an new instance with only its <code>algorithmName</code> set - no hashing is performed.

  Because all other constructors in this class hash the <code>source</code> constructor argument, this

  you can then immediately call <A HREF="../../../../../org/apache/shiro/crypto/hash/SimpleHash.html#setBytes(byte[])"><CODE>setBytes</CODE></A> to have a fully-initialized instance.
