Changes/New default cipher in OpenVPN - Fedora Project Wiki
Blowfish is the default cipher used in OpenVPN, though it can be configured to others. The most commonly used version is Blowfish-128, but it theoretically can range from 32 to 448 bits. The cipher is generally secure but does sport some vulnerabilities. It should generally only be chosen when AES-256 is unavailable.

It is set to AES-256-GCM:AES-128-GCM by default and overrides the --cipher parameter when used with an OpenVPN 2.4 client. For the sake of simplicity, the script set both the --cipher and --ncp-cipher to the cipher chosen above. Control channel. OpenVPN 2.4 will negotiate the best cipher available by default (e.g ECDHE+AES-256-GCM) OpenVPN -cipher vs -tls-cipher? - Information Security OpenVPN uses TLS to protect control channel packets. The 'data channel'. This is the channel over which the actual VPN traffic is sent. This channel is keyed with key material exchanged over the control channel. Both these channels are duplexed over a single TCP or UDP port.--tls-cipher controls the cipher used by the control channel.
New default cipher in OpenVPN Summary. Since the discovery of the SWEET32 flaw, ciphers using cipher-blocks smaller than 128-bits are considered vulnerable and should not be used any more. OpenVPN uses Blowfish (BF-128-CBC) as the default cipher, which is hit by the SWEET32 flaw.This proposal changes the default cipher to AES-256-GCM while in parallel allowing clients to connect …
The clear winner in the battle of VPN protocols is OpenVPN which provides speed and security, but is not an out of the box feature in most operating systems. We recommend OpenVPN because it often offers the best of both worlds (speed and security) when it comes to VPNs services.
