/**
* Poly1305 ([PDF](https://cr.yp.to/mac/poly1305-20050329.pdf),
* [wiki](https://en.wikipedia.org/wiki/Poly1305))
* is a fast and parallel secret-key message-authentication code suitable for
* a wide variety of applications. It was standardized in
* [RFC 8439](https://www.rfc-editor.org/rfc/rfc8439) and is now used in TLS 1.3.
*
* Polynomial MACs are not perfect for every situation:
* they lack Random Key Robustness: the MAC can be forged, and can't be used in PAKE schemes.
* See [invisible salamanders attack](https://keymaterial.net/2020/09/07/invisible-salamanders-in-aes-gcm-siv/).
* To combat invisible salamanders, `hash(key)` can be included in ciphertext,
* however, this would violate ciphertext indistinguishability:
* an attacker would know which key was used - so `HKDF(key, i)`
* could be used instead.
*
* Check out [original website](https://cr.yp.to/mac.html).
