/**
 * <p>MD5 implementation of PasswordEncoder.</p>
 * <p>If a <code>null</code> password is presented, it will be treated as an empty <code>String</code> ("")
 * password.</p>
 * <P>As MD5 is a one-way hash, the salt can contain any characters.</p>
 *
 * This is a convenience class that extends the
 * {@link MessageDigestPasswordEncoder} and passes MD5 as the algorithm to use.
