Struct Rabbit 

pub struct Rabbit { /* private fields */ }

Rabbit stream cipher.

The new constructor applies both the key setup and the RFC IV setup. without_iv leaves the cipher in the key-only state used by the RFC’s key-setup test vectors.

Implementations

impl Rabbit

pub fn new(key: &[u8; 16], iv: &[u8; 8]) -> Self

Create Rabbit from a 128-bit key and 64-bit IV.

pub fn without_iv(key: &[u8; 16]) -> Self

Create Rabbit from a 128-bit key without applying the optional IV setup.

pub fn new_wiping(key: &mut [u8; 16], iv: &mut [u8; 8]) -> Self

Create and wipe the caller’s key and IV buffers.

pub fn without_iv_wiping(key: &mut [u8; 16]) -> Self

Create without IV setup and wipe the caller’s key buffer.

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

XOR the Rabbit keystream into buf in place.

pub fn fill(&mut self, buf: &mut [u8])

Fill buf with keystream bytes by XORing into the existing contents.

pub fn keystream_block(&mut self) -> [u8; 16]

Return the next 16 bytes of keystream.

Trait Implementations

impl Drop for Rabbit

fn drop(&mut self)

Executes the destructor for this type.

impl StreamCipher for Rabbit

fn fill(&mut self, buf: &mut [u8])

XOR keystream bytes into buf in place.

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

Alias for Self::fill for callers that prefer this terminology.
