I would like to use openssl as a basic DTLS server from the command line using: openssl s_server -dtls1_2 The catch is I want to require the TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8 cipher suite. It appears OpenSSL currently doesn?t support this cipher suite, even though it supports the both ECDHE_ECDSA and AES_128_CCM_8 individually as separate operations. Is there some small change I can make to enable support of this cipher suite? Perhaps this is already supported in an un-released version?
