The openvpn man page suggests using "openvpn --genkey"

       --tls-auth file [direction]
              Add an additional layer of HMAC authentication on top of the TLS
              control channel to protect against DoS attacks.

              In  a  nutshell, --tls-auth enables a kind of "HMAC firewall" on
              OpenVPN's TCP/UDP port, where TLS control channel packets  bear-
              ing an incorrect HMAC signature can be dropped immediately with-
              out response.

              file (required) is a file in OpenVPN static key format which can
              be generated by --genkey
