note 119986 added to function.openssl-encrypt

There still seems to be some confusion about the "password" argument to this function. It accepts a binary string for the key (ie. NOT encoded), at least for the cipher methods I tried (AES-128-CTR and AES-256-CTR). One of the posts says you should hex encode the key (which is wrong), and some say you should hash the key but don't make it clear how to properly pass the hashed key. Instead of the post made by anonymous, this should be more accurate info about the parameters: data - BINARY string method - regular string, from openssl_get_cipher_methods() password - BINARY string (ie. the encryption key in binary) options - integer (use the constants provided) iv - BINARY string This is not only from my testing, but backed up by the usage of this function by https://github.com/defuse/php-encryption ---- Server IP: 208.69.120.55 Probable Submitter: 50.149.58.125 ---- Manual Page -- http://php.net/manual/en/function.openssl-encrypt.php Edit -- https://master.php.net/note/edit/119986 Del: integrated -- https://master.php.net/note/delete/119986/integrated Del: useless -- https://master.php.net/note/delete/119986/useless Del: bad code -- https://master.php.net/note/delete/119986/bad+code Del: spam -- https://master.php.net/note/delete/119986/spam Del: non-english -- https://master.php.net/note/delete/119986/non-english Del: in docs -- https://master.php.net/note/delete/119986/in+docs Del: other reasons-- https://master.php.net/note/delete/119986 Reject -- https://master.php.net/note/reject/119986 Search -- https://master.php.net/manage/user-notes.php
