 The `sio` package 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 unqiue
-key-nonce combination using the *AEAD*. For the last fragment the construction prefixes the associated
-data with the `0x80` byte (instead of `0x00`) to prevent truncation attacks.
