Function Documentation

int aes_wrap	(	const u8 *	kek,
		size_t	kek_len,
		int	n,
		const u8 *	plain,
		u8 *	cipher
	)

Wrap keys with AES Key Wrap Algorithm (RFC3394)

Parameters

kek	Key encryption key (KEK)
kek_len	Length of KEK in octets
n	Length of the plaintext key in 64-bit units; e.g., 2 = 128-bit = 16 bytes
plain	Plaintext key to be wrapped, n * 64 bits
cipher	Wrapped key, (n + 1) * 64 bits

Returns

0 on success, -1 on failure
