Struct miscreant::SivAead

pub struct SivAead<C, M> where
    C: NewStreamCipher<NonceSize = U16> + SyncStreamCipher,
    M: Mac<OutputSize = U16>,  { /* fields omitted */ }

The SivAead type wraps the more powerful Siv interface in a more commonly used Authenticated Encryption with Associated Data (AEAD) API, which accepts a key, nonce, and associated data when encrypting/decrypting.

Trait Implementations

impl<C, M> Aead for SivAead<C, M> where
    C: NewStreamCipher<NonceSize = U16> + SyncStreamCipher,
    M: Mac<OutputSize = U16>,
    C::KeySize: Add,
    <C::KeySize as Add>::Output: ArrayLength<u8>, 

type KeySize = <C as NewStreamCipher>::KeySize

Size of a key associated with this AEAD algorithm

type TagSize = U16

Size of a MAC tag

fn new(key: &[u8]) -> Self

Create a new AEAD instance

fn encrypt_in_place(
    &mut self,
    nonce: &[u8],
    associated_data: &[u8],
    buffer: &mut [u8]
)

Encrypt the given plaintext in-place, replacing it with the SIV tag and ciphertext. Requires a buffer with 16-bytes additional space.

fn decrypt_in_place<'a>(
    &mut self,
    nonce: &[u8],
    associated_data: &[u8],
    buffer: &'a mut [u8]
) -> Result<&'a [u8], Error>

Decrypt the given ciphertext in-place, authenticating it against the synthetic IV included in the message.

fn encrypt(
    &mut self,
    nonce: &[u8],
    associated_data: &[u8],
    plaintext: &[u8]
) -> Vec<u8>

Encrypt the given plaintext, allocating and returning a Vec for the ciphertext

fn decrypt(
    &mut self,
    nonce: &[u8],
    associated_data: &[u8],
    ciphertext: &[u8]
) -> Result<Vec<u8>, Error>

Decrypt the given ciphertext, allocating and returning a Vec for the plaintext
