Alex Rudyy updated QPID-7056:
-----------------------------
    Description: 
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.

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.
