This value must be identical on ALL nodes and lighthouses. Nebula does not support the use of different ciphers simultaneously!

cipher allows you to choose between the available ciphers for your network. You may choose chachapoly to use the ChaCha20-Poly1305 cipher or aes for AES256-GCM.

Because most devices have hardware support for the AES instruction set (e.g. AES-NI), this is the recommended option.

cipher: aes
