+Generic hashing framework for PHP
+
+Simplest usages:
+
+$digest = hash($algoname, $message);
+$digest = hash_file($algoname, $filename);
+
+Examples:
+
+$digest = hash('md5', 'The quick brown fox jumped over the lazy dog.');
+
+Feeder usage:
+
+$context = hash_init($algoname);
+hash_update($context, $message);
+$digest = hash_final($context);
+
+hash(), hash_file(), and hash_final() each support an optional boolean parameter $raw_output which behaves in the same 
+manner as sha1()'s optional parameter.
