In netscape, I set following options "security info -> navigator -> No encryption with an MD5 MAC" without no other algorithm ("RC4 encryption with a 128-bit key and an MD5 MAC" ...) then, connect in apache SSL server (modssl-2.1.7-1.3.6, apache-1.3.6, openssl-0.9.2b). In server error_log, the following message appeared "OpenSSL: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher" In Client, the following message appeared "no common encryption algorithm" I want use SSL without certificate, so selected "no encryption with an MD5 MAC". It is possible?
