   These functions are intended to work with <link
   xlink:href="&url.mhash;">mhash</link>. Mhash can be used to create checksums,
   message digests, message authentication codes, and more.

  <para>
   This is an interface to the mhash library. Mhash supports a wide
   variety of hash algorithms such as MD5, SHA1, GOST, and many
   others. For a complete list of supported hashes, refer to the
   <link linkend="mhash.constants">constants page</link>. The general rule is that you can access
   the hash algorithm from PHP with <constant>MHASH_hashname</constant>. For example, to
   access TIGER you use the PHP constant <constant>MHASH_TIGER</constant>.

    This extension is obsoleted by <link linkend="book.hash">Hash</link>.

  <note>
   <para>
    As of PHP 7.0.0 the Mhash extension has been fully integrated into the <link
    linkend="book.hash">Hash</link> extension. Therefore, it is no longer
    possible to detect Mhash support with <function>extension_loaded</function>;
    use <function>function_exists</function> instead. Furthermore, Mhash is no
    longer reported by <function>get_loaded_extensions</function> and related
    features.
