note 110047 added to function.openssl-encrypt

For security reasons, if NOT encrypting using a (cryptographically) random IV, then the IV itself must be entryptet as well ( this is not handled behind the scene). the reason is that it leads to predictable IV's, which then breaks semantic security. [this kind of attack can already be done on ssl/ TLS 1.1]. ---- Server IP: 69.147.83.197 Probable Submitter: 84.238.54.123 ---- Manual Page -- http://www.php.net/manual/en/function.openssl-encrypt.php Edit -- https://master.php.net/note/edit/110047 Del: integrated -- https://master.php.net/note/delete/110047/integrated Del: useless -- https://master.php.net/note/delete/110047/useless Del: bad code -- https://master.php.net/note/delete/110047/bad+code Del: spam -- https://master.php.net/note/delete/110047/spam Del: non-english -- https://master.php.net/note/delete/110047/non-english Del: in docs -- https://master.php.net/note/delete/110047/in+docs Del: other reasons-- https://master.php.net/note/delete/110047 Reject -- https://master.php.net/note/reject/110047 Search -- https://master.php.net/manage/user-notes.php
