Struct Aes128Kwp 

pub struct Aes128Kwp;

SP 800-38F KWP with AES-16*8, per RFC 5649.

Implementations

impl Aes128Kwp

pub const KEY_LEN: usize = 16

Key-encryption key length.

pub const fn wrapped_len(plaintext_len: usize) -> usize

Output length for a given input length: padded up to a multiple of eight, plus the eight-byte header.

pub fn wrap(kek: &[u8], plaintext: &[u8], out: &mut [u8]) -> Result<()>

Wrap data of any length from one byte upwards.

The length is carried in the check value, so unwrapping recovers it exactly. It is not hidden: an observer learns the length to within eight bytes from the ciphertext size alone.

pub fn unwrap(kek: &[u8], ciphertext: &[u8], out: &mut [u8]) -> Result<usize>

Unwrap, returning the recovered length.

out must be large enough for the padded data; the return value says how much of it is real.

Trait Implementations

impl Algorithm for Aes128Kwp

const ID: &'static str = "aes-128-kwp"

Stable ontology identifier for this algorithm.

const NAME: &'static str = "aes-128-kwp"

Human-facing display name (for example "SHA-256").
