Ciphers (algorithms) are used to encrypt and decrypt data as it traverses a VPN connection. Algorithms based on AES are common and secure, and are widely supported by VPN implementations. AES-GCM, or AES Galois/Counter Mode is an efficient and fast authenticated encryption algorithm, which means it provides data privacy as well as integrity validation, without the need for a separate integrity algorithm. Additionally, AES-based algorithms can often be accelerated by AES-NI.
TNSR supports a number of common, secure encryption algorithms including 3DES, AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-ICV16-GCM-128, AES-ICV16-GCM-192, AES-ICV16-GCM-256, Camellia-128,Camellia-192, Camellia-256 and CHACHA20-POLY1305.
