*
* ChaCha20 and the ChaCha20_Poly1305 construction are defined in RFC 7539.
*
* Implementations must support 12-byte nonces, may support 8-byte nonces,
* and should reject other sizes.
* \note For ChaCha20 and ChaCha20_Poly1305, Mbed TLS only supports
* 12-byte nonces.
*
* \note For ChaCha20, the initial counter value is 0. To encrypt or decrypt
* with the initial counter value 1, you can process and discard a
* 64-byte block before the real data.
