Cryptographic
Task 5 / 47
crypto_sha256
Implement or tune the SHA-256 compression function for speed on representative message lengths with bit-exact agreement on standard vectors. The task stresses bitwise rounds, unrolling, and memory behavior—typical hash primitive optimization in TLS and blockchain stacks.
