Viktor and Michael have already provided some excellent advice on this
so I won't cover the same ground. Just one note on this line though -
this is actually unnecessary in modern versions of OpenSSL (anything
from OpenSSL 1.1.0 and above). It's a no-op in modern versions - "auto"
ecdh is the default.
