Struct rabbit::Rabbit

pub struct Rabbit { /* fields omitted */ }

Rabbit stream cipher state.

Implementations

impl Rabbit

pub fn setup_without_iv(key: [u8; 16]) -> Rabbit

Creates an empty rabbit state, then setups the given key on it.

See RFC 4503 3.2. Initialization Vector (page 5).

pub fn setup(key: [u8; 16], iv: [u8; 8]) -> Rabbit

Creates an empty rabbit state, then setups the given key and iv on it.

pub fn reset(&mut self)

Restores master state (iv will be lost).

pub fn reinit(&mut self, iv: [u8; 8])

Restores master state, than setups initialization vector iv on it.

pub fn encrypt_inplace(&mut self, data: &mut [u8]) -> bool

Encrypts bytes of data inplace.

Returns:

• true – OK;
• false – max message length (16 * 2⁶⁴ bytes) was exceeded. data is not affected.

pub fn decrypt_inplace(&mut self, data: &mut [u8]) -> bool

Decrypts bytes of data inplace (see Rabbit::encrypt_inplace).

Trait Implementations

impl Debug for Rabbit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl NewStreamCipher for Rabbit

type KeySize = U16

Key size in bytes

type NonceSize = U8

Nonce size in bytes

fn new(key: &Key<Self>, iv: &Nonce<Self>) -> Self

Create new stream cipher instance from variable length key and nonce.

fn new_var(key: &[u8], nonce: &[u8]) -> Result<Self, InvalidKeyNonceLength>

Create new stream cipher instance from variable length key and nonce.

impl SyncStreamCipher for Rabbit

fn try_apply_keystream(&mut self, data: &mut [u8]) -> Result<(), LoopError>

Apply keystream to the data, but return an error if end of a keystream will be reached.

fn apply_keystream(&mut self, data: &mut [u8])

Apply keystream to the data.
