Crate prikk_hash 

Hash primitives used by Prikk.

sha256 runs on the audited sha2 crate. Prikk originally shipped a first-party SHA-256 implementation for the initial source drop; DC-50 concluded the ROI no longer favoured maintaining it (identity-bearing maintenance cost, a measured ~5.8x throughput gap, and no remaining supply-chain benefit once sha2 was already trusted for Ed25519 signing via ed25519-dalek), and DC-55 performed the swap after an equivalence campaign proved it changed no existing identity. The outgoing implementation is retained test-only, frozen, as an independent differential reference — see tests::frozen_outgoing.

#![forbid(unsafe_code)] remains true of this crate’s own source, but hashing now happens inside sha2, whose accelerated backends use unsafe internally for CPU-specific instructions. This crate no longer provides an unsafe-free guarantee for hashing by itself.
