That isn't good example. First, there is one additional connection between server and client. Second, attacker could be get a key because in first connection it is going to client as plain text. I think, server have to get a key in other way. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
