note 20128 added to ref.mcrypt

Does anyone know of a RSA implementation in php? I'm trying to securely transfer information from the browser to the server without using SSL. I got a javascript in the client encrypting the data and posting it to the server, but I need the php script to be able to decrypt the data. Yes, I know this is very much vulnerable to man-in-the-middle attacks, but at least it prevents passive sniffing. Does anyone know of such a beast, or should I spend a couple of hours converting an existing implementation to PHP? -- http://www.php.net/manual/en/ref.mcrypt.php http://master.php.net/manage/user-notes.php?action=edit+20128 http://master.php.net/manage/user-notes.php?action=delete+20128 http://master.php.net/manage/user-notes.php?action=reject+20128
