Secure IO

The sio crate implements provable secure authenticated encryption for continuous byte streams.
It splits a data stream into L bytes long fragments and en/decrypts each fragment with an unique key-nonce combination using an AEAD. For the last fragment the construction prefixes the associated data with the 0x80 byte (instead of 0x00) to prevent truncation attacks.

The sio crate follows semantic versioning and hasn't reached a stable v1.0.0, yet. So newer versions may cause major breaking API changes. However, we try to avoid such changes - if not really needed.

How to use sio?

1. Add it as dependency to your Cargo.toml: sio = "0.2.0".
2. Use it within your application or crate:

   extern crate sio
   
   use sio;
