Have you tried (in separate windows or otherwise concurrent, with the server started first): $ openssl s_server -nocert -cipher aNULL -accept 12345 $ openssl s_client -cipher aNULL -connect localhost:12345 If that does not crash, try with the actual certificate you're using (replace -nocert with "-cert your-cert-file.pem" and drop the "-cipher" options). -- Viktor.
