+ * Ability to define "_NANO_SHA2_UPPER" to yeild upper case hashes.
+ * 2009-08-01: Added ability to attempt to use mhash() prior to running pure

+ *
+ * NOTE: Some sporadic versions of PHP do not handle integer overflows the

+ *
+ * If you do not have permissions to change PHP versions (if you did
+ * you'd probably upgrade to PHP 5 anyway) it is advised you install a
+ * module that will allow you to use their hashing routines, examples are:
+ * - mhash module : http://ca3.php.net/mhash
+ * - Suhosin : http://www.hardened-php.net/suhosin/
+ *
+ * If you install the Suhosin module, this script will transparently
+ * use their routine and define the PHP routine as _nano_sha256().
+ *
+ * If the mhash module is present, and $ignore_php5_hash = false the
