1Generic hashing framework for PHP 2 3Simplest usages: 4 5$digest = hash($algoname, $message); 6$digest = hash_file($algoname, $filename); 7 8Examples: 9 10$digest = hash('md5', 'The quick brown fox jumped over the lazy dog.'); 11 12Feeder usage: 13 14$context = hash_init($algoname); 15hash_update($context, $message); 16$digest = hash_final($context); 17 18hash(), hash_file(), and hash_final() each support an optional boolean parameter $raw_output which behaves in the same 19manner as sha1()'s optional parameter. 20
