An Erlang implementation of the Noise protocol
enoise provides a generic handshake mechanism, that can be used in a couple
of different ways. There is also a plain gen_tcp-wrapper, where you can
"upgrade" a TCP socket to a Noise socket and use it in much the same way as you
would use gen_tcp.
When using enoise to do an interactive handshake, enoise will only take
care of message composition/decompositiona and encryption/decryption - i.e. the
user has to do the actual sending and receiving.
An example of the interactive handshake can be seen in the noise_interactive
test in test/enoise_tests.erl.
There is also the option to use an automated handshake procedure. If provided with a generic Communication state that describe how data is sent and received, the handshake procedure is done automatically. The result of a successful handshake is two Cipher states that can be used to encrypt/decrypt a RX channel and a TX channel respectively.
The provided gen_tcp-wrapper is implemented using the generic handshake, see
src/enoise.erl.
