Struct Eax 

pub struct Eax<C> { /* private fields */ }

EAX AEAD with a full 16-byte detached tag.

Implementations

impl<C> Eax<C>

pub fn new(cipher: C) -> Self

Wrap a 128-bit block cipher in EAX mode.

pub fn cipher(&self) -> &C

Borrow the wrapped cipher.

impl<C: BlockCipher> Eax<C>

pub fn encrypt(&self, nonce: &[u8], aad: &[u8], data: &mut [u8]) -> [u8; 16]

Encrypt data in place and return a detached 16-byte tag.

pub fn decrypt( &self, nonce: &[u8], aad: &[u8], data: &mut [u8], tag: &[u8; 16], ) -> bool

Verify and decrypt data in place.

Returns false and leaves data unchanged on authentication failure.

Trait Implementations

impl<C: BlockCipher> Aead for Eax<C>

type Tag = [u8; 16]

Detached authentication tag type.

fn encrypt_in_place( &self, nonce: &[u8], aad: &[u8], data: &mut [u8], ) -> Self::Tag

Encrypt data in place and return its authentication tag.

fn decrypt_in_place( &self, nonce: &[u8], aad: &[u8], data: &mut [u8], tag: &Self::Tag, ) -> bool

Decrypt data in place after authenticating tag.

fn encrypt( &self, nonce: &[u8], aad: &[u8], plaintext: &[u8], ) -> (Vec<u8>, Self::Tag)

Encrypt plaintext and return (ciphertext, tag).

fn decrypt( &self, nonce: &[u8], aad: &[u8], ciphertext: &[u8], tag: &Self::Tag, ) -> Option<Vec<u8>>

Decrypt ciphertext and return plaintext on successful authentication.
