> During TLS handshaking, the client requests to negotiate a cipher suite from a list of cryptographic options that it supports, starting with its first preference. Then, the server selects a single cipher suite from the list of cipher suites requested by the client. Normally, the selection honors the client's preference.
> Both Qpid Broker and Client need to be able influence the order of cipher suites to negotiate. At the moment, the order of cipher suites is defined in JDK implementations. For example, in Oracle 1.8 JDK GCM cipher suites (for example, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, etc) are faster then TLS_ECDHE_RSA_WITH_AES_255_CBC_SHA384 but cipher suite TLS_ECDHE_RSA_WITH_AES_255_CBC_SHA384 is selected during negotiation of TLS. Both broker and client should be able to override the order of cipher suites. Thus, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 should be considered before TLS_ECDHE_RSA_WITH_AES_255_CBC_SHA384.
> Additionally, Broker should be able to select cipher suites based on its own preference rather than the client's preference in order to mitigate the risks of using weak cipher suites.
