I am now using this ciphersuite:


I am using OpenSSL 1.0.1m, with Apache 2.2 on my Synology NAS. My problem is, that ECDHE-ECDSA ciphers are not in use. (tested on ssllabs: https://www.ssllabs.com/ssltest/analyze.html?d=sufix.cz&s=

Why does this happen? Is it just beacuse of syntax error or too old versions?

Do you have an ECDSA certificate?

    @Mat Yes. The signature algorithm in the cipher suite uses the key in your cert, so ECDSA requires a cert with an ECDSA key.
