bl_sha256_verify()

int bl_sha256_verify	(	const uint8_t *	data,
		uint32_t	data_len,
		const uint8_t *	expected
	)

#include <include/bl_crypto.h>

Calculate a digest and verify it directly.

Parameters

[in]	data	The data to hash.
[in]	data_len	The length of data.
[in]	expected	The expected digest over data.

Return values

0	If the procedure succeeded and the resulting digest is identical to expected.
-EHASHINV	If the procedure succeeded, but the digests don't match.

Returns

Any error code from bl_sha256_init, bl_sha256_update, or bl_sha256_finalize if something else went wrong.
