Re : Encryption Hardening for ServiceDesk Webserver

Support for ECDSA instead of RSA?
Support for AES-256?
Support for ECDHE?
Support for SHA256?

ie:

TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384

Please confirm as most of the of stronger encryption methods are missing the from the list in the link supplied.

Thanks!  :)
