Function Documentation

struct DigestContext* digest_new	(	const struct DigestInfo *	impl,
		CxMem *	cx
	)		[read]

Allocate and initialize new algorithm instance.

void digest_update	(	struct DigestContext *	ctx,
		const void *	data,
		size_t	len
	)

Hash more data.

void digest_final	(	struct DigestContext *	ctx,

	)

Get final result.

To re-use same instance, digest_reset() must be called first.
