I ran openssl s_server with an ECC certificate signed by an RSA Root CA. When I try to connect using s_client and a TLS 1.2 ECDH-RSA cipher suite (eg ECDH-RSA-AES128-SHA256 or ECDH-RSA-AES128-GCM-SHA256), the connection fails with s_server printing the following error: "3086918464:error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher:s3_srvr.c:1353:". Can someone please tell me why this doesn't work? Here are the commands I used:
Starting s_server: openssl s_server -accept 4433 -key ./key.pem -cert cert.pem Connecting with s_client: openssl s_client -connect localhost:4433 -cipher ECDH-RSA-AES128-SHA256 Thanks Abhi
