+- Build enable-ec_nistp_64_gcc_128, ecdh is many times faster
+  but only works in x86_64.
+  According to the openSSL team
+"it is superior to the default in multiple regards (speed, and also
+security as the new implementations are secure against timing
+attacks)"
+It is not enabled by default due to the build system being unable
+to detect if the compiler supports __uint128_t.
