4//! Hash functions for arcana.
5//!
6//! Every algorithm now lives in the shared [`krypteia-tessera`](tessera)
7//! crate; this module is a thin façade that re-exports the types and,
8//! via the blanket impls in [`crate`], exposes them through arcana's own
9//! [`Hasher`](crate::Hasher) / [`Xof`](crate::Xof) traits. The
10//! per-algorithm submodules (`sha256`, `sha3`, …) are kept as path
11//! aliases so existing `crate::hash::sha256::Sha256` imports keep
12//! working unchanged.
