8//! # SpongeHash-AES256
9//!
10//! A [**sponge**](https://en.wikipedia.org/wiki/Sponge_function)-based secure hash function that uses [AES-256](https://docs.rs/aes/latest/aes/index.html) as its internal [PRF](https://en.wikipedia.org/wiki/Pseudorandom_permutation).
11//!
12//! This hash function has a *variable* output size and can produce outputs of *any* non-zero size (up to [`usize::MAX`]).
13//!
14//! Please see the **[`SpongeHash256`]** struct for details! &#128161;
15//!
16//! ## Dependencies
