Setting up network encryption in GlusterFS

Introduction GlusterFS has supported network encryption using TLS/SSL since GlusterFS-3.5. GlusterFS-3.5 supported encryption only on the I/O connections, ie. the connections between GlusterFS clients and servers. GlusterFS-3.6 introduced support for encrypting the manangement connections, the connections between GlusterDs within a trusted storage pool. When using network encryption, GlusterFS also uses TLS/SSL for authentication and authorization, in place of the home grown auth framework used for normal connections. Though encryption has been supported for quite some time, the number of users using it has been minimal.
