+Use the incorrect behaviour of older OpenSSL implementations when computing
+endpoint-pair shared secrets for DTLS/SCTP. This allows communication with
+older broken implementations but breaks interoperability with correct
+implementations. Must be used in conjunction with B<-sctp>. This option is only
