+                When setting up a new encrypted connection some encryption protocols allow you to have part of the
+                handshake (the 'hello') encapsulated in an SSLv2 format. The SSLv2Hello option below controls this
+                encapsulation. When disabled, all incoming data must conform to the SSLv3/TLSv1 handshake format, and
+                all outgoing data (which applies to outbound server-to-server connections) will conform to the SSLv3/TLSv1
+                format.
