Hashing

A tiny one‑header C++ library called CT hash wraps OpenSSL to replace its clunky allocate/init/update/finalize dance with typed value and hasher objects that avoid needless allocations and duplicate helpers. It supports SHA‑2, SHA‑3 and XX families, provides literal and streaming IO, converts to hex or base64 on demand, and lets SHAKE produce arbitrary‑length output so you can request an 8‑byte short hash or use SHAKE as RNG to stream bytes indefinitely.
