There are several elements that make up OpenVPN encryption: server authentication, the data channel, the control channel, and HMAC authentication: Server authentication verifies that the server you are talking to is trustworthy. OpenVPN authenticates servers in the same way as HTTPS, using TLS certificates.
OpenVPN supports the CBC, CFB, and OFB cipher modes, however CBC is recommended and CFB and OFB should be considered advanced modes. Set alg=none to disable encryption . This may effect other elements of your VPN ..

When it comes to encryption, the devil is in the OpenVPN's default encryption algorithm BF-CBC (Blowfish, block-cipher) with a 128-bit (variable) key size. While it's certainly not a terrible or 'broken' cipher like RC4 or single-DES, I prefer a more modern and widely used cipher like AES. Out of all other strong options, I've chosen AES-256-CBC for interoperability with OpenVPN-NL. Openvpn 2.4 introduced a new feature, enabled by default for negotiating crypto parameters. I'm not sure if this was a reaction to sweet32 or a result of general concerns about the implications of being effectively locked into a single cipher-suite.

Apr 04, 2018 · OpenVPN. OpenVPN uses open-source technologies like the OpenSSL encryption library and SSL v3/TLS v1 protocols. It can be configured to run on any port, so you could configure a server to work over TCP port 443. OpenVPN encryption is comprised of two parts: data channel and control channel encryption. The former consists of a cipher and hash authentication – both of which will be discussed later in this article – and is used to secure the data itself.
