TorGuard software is powered by OpenVPN, an open source VPN protocol that offers many encryption choices. We have now added new encryption cipher selections to all VPN servers, allowing users the power to pick their own VPN encryption settings. Cipher (Data Encryption)
AES-256-CBC is probably "the best". AES-128-CBC is roughly 2x the speed however, at least according to openssl, and is perfectly fine for all but the highest security traffic.

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. The Comprehensive Guide to VPN Encryption Ciphers Encryption Ciphers. Here are the main types of encryption ciphers you will see VPN providers use: The Blowfish Cipher – Blowfish is normally accompanied by a 128-bit key. It is deemed safe, but there are some online users that worry about its reliability. Blowfish is the default cipher used in OpenVPN, though it can be configured to others networking - Which openvpn cipher should I use? - Server Fault
Aug 28, 2018 · The default encryption for the transport protocol of OpenVPN is Blowfish – a 64-bit cipher – with the CBC mode. Meaning, the default encryption of OpenVPN prior to version 2.4 is BF-CBC which doesn't provide enough security in recent times.
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. vyos@vyos# set interfaces openvpn vtun1 encryption cipher Possible completions: des DES algorithm 3des DES algorithm with triple encryption bf128 Blowfish algorithm with 128-bit key bf256 Blowfish algorithm with 256-bit key aes128 AES algorithm with 128-bit key CBC aes128gcm AES algorithm with 128-bit key GCM aes192 AES algorithm with 192-bit key CBC aes192gcm AES algorithm with 192-bit key OpenVPN Ciphers. Encryption is a method of securing your securing by scrambling it into an unreadable format. The job of encryption data is handled by a cipher. The stronger the cipher, the stronger the encryption, and the tougher it is to crack into it. The most commonly used cipher today is AES (Advanced Encryption Standard). The trick used by NordVPN is the AES-256-CBC (Cipher Block Chaining) encryption that is applied not once, but twice. It also supports OpenVPN , PPTP , L2TP and IPSec protocols and extra security features such as safety notes and an encrypted chat. Oct 03, 2018 · The packet is then forwarded to the userspace OpenVPN process, where the headers are stripped. The packet is encrypted and signed using OpenSSL calls. The encryption and signing algorithms can be configured using the '--cipher' and '--auth' options. Jun 26, 2020 · Camellia is an innovative cipher the users can consider in place of AES cipher. However, it does not offer the level of security as AES provides to the users. Handshake Encryption. OpenVPN, a VPN protocol uses handshake encryption that enables the OpenVPN client and VPN server to create secret keys. Mar 29, 2017 · OpenVPN uses the 128-bit Blowfish cipher. It is generally considered secure, but there is also a push to move towards Twofish instead. Other options include the various AES ciphers such as AES-128, AES-192 and AES-256. All of the AES ciphers are considered secure, but it is recommend that you use AES-256 if you have serious security concerns.
