Struct Siv 

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

RFC 5297 SIV construction parameterized by two block-cipher instances.

Implementations

impl<C> Siv<C>

pub fn new(mac_cipher: C, ctr_cipher: C) -> Self

Construct from separate CMAC and CTR ciphers.

pub fn mac_cipher(&self) -> &C

Borrow the CMAC-side cipher.

pub fn ctr_cipher(&self) -> &C

Borrow the CTR-side cipher.

impl<C: BlockCipher> Siv<C>

pub fn encrypt_with_components( &self, components: &[&[u8]], plaintext: &[u8], ) -> (Vec<u8>, [u8; 16])

Encrypt using an explicit ordered vector of associated-data components.

pub fn decrypt_with_components( &self, components: &[&[u8]], ciphertext: &mut [u8], tag: &[u8; 16], ) -> bool

Decrypt/authenticate using an explicit vector of associated-data components.

pub fn encrypt( &self, nonce: &[u8], aad: &[u8], plaintext: &[u8], ) -> (Vec<u8>, [u8; 16])

Encrypt and return (ciphertext, detached_tag).

RFC 5297 treats the nonce as an associated-data component.

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

Authenticate and decrypt in place.

Returns false and leaves ciphertext unchanged on failure.

Trait Implementations

impl<C: BlockCipher> Aead for Siv<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.
