The next step is to create the keys for the server../build-key-server server Again, you can confirm the settings you’ve already defined in vars by hitting enter. This time, though, there will be two additional prompts: port 1194 proto udp dev tun ca ca.crt cert server.crt key server.key # This file should be kept secret dh dh.pem server 10.8.0.0 255.255.255.0 push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 208.67.222.222" push "dhcp-option DNS 208.67.220.220" keepalive 10 120 tls-auth ta.key 0 # This file is secret cipher AES-256-CBC user We will do the key generation in next step. dh dh2048.pem Next, uncomment the push “redirect-gateway def1 bypass-dhcp” line, which tells the client to redirect all traffic through our OpenVPN. OpenVPN Client Key Generator. GitHub Gist: instantly share code, notes, and snippets. May 13, 2020 · $ openvpn --genkey --secret ta.key Once generated, we move the ta.key file to /etc/openvpn: $ sudo mv ta.key /etc/openvpn Our server keys setup is now complete. We can proceed with the actual server configuration. Step 6 - OpenVPN configuration. The OpenVPN configuration file doesn’t exist by default inside /etc/openvpn. Once the OpenVPN peers are sure about each other's identity, DH can be used to create a shared secret key for the hash function and the cipher algorithm. By combining a DH private key with the other OpenVPN box DH public key, it is possible to calculate a shared secret that only the two OpenVPN peers know. While pre-1.5 versions of OpenVPN generate 1024 bit key files, any version of OpenVPN which supports the direction parameter, will also support 2048 bit key file generation using the --genkey option. (snip) --key-direction Alternative way of specifying the optional direction parameter for the --tls-auth and --secret options.

Using tls-auth requires that you generate a shared-secret key that is used in addition to the standard RSA certificate/key: openvpn --genkey --secret ta.key. This command will generate an OpenVPN static key and write it to the file ta.key. This key should be copied over a pre-existing secure channel to the server and all client machines.
