Struct eax::Eax

pub struct Eax<Cipher> where
    Cipher: BlockCipher<BlockSize = U16> + NewBlockCipher + Clone,
    Cipher::ParBlocks: ArrayLength<Block<Cipher>>,  { /* fields omitted */ }

EAX: generic over an underlying block cipher implementation.

This type is generic to support substituting alternative cipher implementations.

If in doubt, use the built-in [Aes128Eax] and [Aes256Eax] type aliases.

Trait Implementations

impl<Cipher> AeadInPlace for Eax<Cipher> where
    Cipher: BlockCipher<BlockSize = U16> + NewBlockCipher + Clone,
    Cipher::ParBlocks: ArrayLength<Block<Cipher>>, 

type NonceSize = Cipher::BlockSize

The length of a nonce.

type TagSize = <Cmac<Cipher> as Mac>::OutputSize

The maximum length of the nonce.

type CiphertextOverhead = U0

The upper bound amount of additional space required to support a ciphertext vs. a plaintext.

fn encrypt_in_place_detached(
    &self,
    nonce: &Nonce<Self::NonceSize>,
    associated_data: &[u8],
    buffer: &mut [u8]
) -> Result<Tag, Error>

Encrypt the data in-place, returning the authentication tag

fn decrypt_in_place_detached(
    &self,
    nonce: &Nonce<Self::NonceSize>,
    associated_data: &[u8],
    buffer: &mut [u8],
    tag: &Tag
) -> Result<(), Error>

Decrypt the message in-place, returning an error in the event the provided authentication tag does not match the given ciphertext (i.e. ciphertext is modified/unauthentic)

fn encrypt_in_place(
    &self,
    nonce: &GenericArray<u8, Self::NonceSize>,
    associated_data: &[u8],
    buffer: &mut dyn Buffer
) -> Result<(), Error>

Encrypt the given buffer containing a plaintext message in-place.

fn decrypt_in_place(
    &self,
    nonce: &GenericArray<u8, Self::NonceSize>,
    associated_data: &[u8],
    buffer: &mut dyn Buffer
) -> Result<(), Error>

Decrypt the message in-place, returning an error in the event the provided authentication tag does not match the given ciphertext.

impl<Cipher: Clone> Clone for Eax<Cipher> where
    Cipher: BlockCipher<BlockSize = U16> + NewBlockCipher + Clone,
    Cipher::ParBlocks: ArrayLength<Block<Cipher>>, 

fn clone(&self) -> Eax<Cipher>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Cipher> NewAead for Eax<Cipher> where
    Cipher: BlockCipher<BlockSize = U16> + NewBlockCipher + Clone,
    Cipher::ParBlocks: ArrayLength<Block<Cipher>>, 

type KeySize = Cipher::KeySize

The size of the key array required by this algorithm.

fn new(key: &Key<Cipher>) -> Self

Create a new AEAD instance with the given key.

fn new_varkey(key: &[u8]) -> Result<Self, Error>

Create new AEAD instance from key with variable size.
