Module sha256 

Minimal pure-Rust SHA-256 (FIPS 180-4) for the blind-test manifest hash. Deterministic, dependency-free (scc-cli has no crypto dep), panic-free. Public only so the roundtrip unit test can exercise it directly.

Functions

digest

SHA-256 digest of data as 32 raw bytes.

hex

Lowercase hex of the SHA-256 digest.
