Внимание
К настоящему времени эта функция еще не была документирована; для ознакомления доступен только список аргументов.
Список параметров
-
data -
The data.
-
method -
The digest method.
-
raw_output -
Setting to
TRUEwill return as raw output data, otherwise the return value is binhex encoded.
Возвращаемые значения
Returns the digested hash value on success или FALSE в случае возникновения ошибки.
Ошибки

Коментарии
The second argument should be one of the values returned by openssl_get_md_methods() rather than hash_algos(). ‘Hash’ and ‘OpenSSL’ are independent extensions and support different selection of digest algorithms. Notably, Hash supports some non-cryptographic hashes like adler or crc.
