Data Fields
ra8_err_t(*	init )(void *ctx)
	Reset the caller-owned context for a SHA-256 operation.
ra8_err_t(*	update )(void ctx, const uint8_t data, uint16_t len)
	Feed one ordered byte span to the running hash.
ra8_err_t(*	final )(void *ctx, uint8_t out[k_ra8_mdl_sha256_bytes])
	Finalise the hash into the caller-provided digest.
void *	ctx
	Hash context passed to every function.

Detailed Description

Streaming SHA-256 seam with caller-owned fixed storage.

The implementation may wrap RSIP, PSA Crypto, or a bounded software implementation. The coordinator never allocates or knows the concrete context type.

Invariant: init, update, final, and ctx are non-null.; final writes exactly k_ra8_mdl_sha256_bytes bytes.

ra8_mdl_sha256_iface_t hash = {
  .init = sha_init, .update = sha_update, .final = sha_final, .ctx = &sha,
};
