/**
 * GHash from AES-GCM and its little-endian "mirror image" Polyval from AES-SIV.

 * Implemented in terms of GHash with conversion function for keys
 * GCM GHASH from

 * SIV from
 * [RFC 8452](https://datatracker.ietf.org/doc/html/rfc8452).
 *
 * GHASH   modulo: x^128 + x^7   + x^2   + x     + 1
 * POLYVAL modulo: x^128 + x^127 + x^126 + x^121 + 1
