Detailed Description

Primitive.

This cipher is only used to debug the library and does absolutely nothing, in other words, it is the identity permutation. It accepts no key, that is it only accepts a key length of zero bytes. Its block size is 128 bits and is arbitrarily chosen.

ORDO_PUBLIC int nullcipher_init	(	struct NULLCIPHER_STATE *	state,
		const void *	key,
		size_t	key_len,
		const void *	params

Return values

ORDO_KEY_LEN

if the key length is not zero.
