#include <ra8_ota.h>

Data Fields
ra8_err_t(*	sha256_init )(void *ctx)
	Begin a SHA-256 streaming hash.
ra8_err_t(*	sha256_update )(void *ctx, const uint8_t *data, uint32_t len)
	Feed bytes to the running SHA-256 hash.
ra8_err_t(*	sha256_final )(void *ctx, uint8_t out[k_ra8_ota_sha256_bytes])
	Finalise and write the 32-byte digest to out.
ra8_err_t(*	ecdsa_verify )(void *ctx, uint32_t pubkey_handle, const uint8_t digest[k_ra8_ota_sha256_bytes], const uint8_t *sig, uint32_t sig_len)
	Verify sig is a valid ECDSA signature over digest using the public key referenced by pubkey_handle.
void *	ctx
	Opaque context passed back to every callback.

Detailed Description

Injected hash + ECDSA verification interface.

Same Dependency-Inversion pattern as ra8_ota_net_iface_t. A concrete implementation lives outside this module (mbedtls or tf-psa-crypto adapter); unit tests pass a mock that scripts happy-path / mismatch behaviour.
